Why You Need Professional Virus Removal

by

“Your computer has a virus.” Such a dreaded five words! We don’t want to come down with a human virus; we’ll feel awful and miss work. But when a virus hits our computer, we could lose valuable information or be vulnerable to attack. Chicken soup won’t cut it.

Perhaps you have an antivirus product installed on your computer. This computer software is intended to prevent, detect, and remove viruses. Antivirus tools are designed to keep infections out. They can also delete any viruses that may already be on the computer when the software is installed.

The software provides protection by tracking malicious code and other computer threats via:

  • classifying the actions the file or code drives (as malicious or OK);
  • inspecting file signatures for matches to an existing signature in its virus dictionary;
  • scanning for rootkits that can change how your operating system functions.

However, antivirus software isn’t that good at cleaning up. When it detects a malicious file, it will delete it. But what if the virus spread before discovery? If the infection spreads before virus deletion, it can do all sorts of damage.

Think of it this way: you have a cyst on your knee. Doctors decide it is pre-cancerous and operate to remove the cyst before it spreads. But, that’s all they do. They have seen the cyst. They go for the cyst. However, they don’t notice the cancer that’s in your shin or femur, because they were only working on the cyst. The rest of your leg remains unhealthy, and you don’t even know it!

Getting a Second Opinion on Viruses

If the antivirus software is your primary physician, a computer professional is the specialist you go to for an expert second opinion. For one thing, antivirus products don’t always remove all the malicious files. Many viruses start as one thing but can mutate into several different strains. The antivirus software may not be programmed to identify all of the virus variants. A professional actively looks for undetected strains on your computer.

Viruses are always evolving. A recent strain of malware, SquirtDanger, let hackers take computer screenshots, capture passwords, download files, and empty out cryptocurrency wallets.

Some viruses can change the settings of your computer. For instance, a common virus changes your computer’s DNS, which is like a bit like the Yellow Pages for the internet. On a virus-free computer, when you type in “Google.com”, your browser goes to Google’s servers located at the IP address “216.58.203.100.” However, an infection can make Google.com on your computer go to a different address. Perhaps a server address cybercriminals use to capture your personal data. It still looks to you like Google, but it’s no longer safe. These settings can still remain after the infection is long gone.

Viruses can also leave behind browser toolbars, extensions, and other nasties designed to spy on your Web browsing habits. If you’re consistently redirected to unwanted sites, or seeing unwanted pop-up advertisements, it’s likely your computer’s infected with a browser hijacker.

Ultimately, if you detect a virus on your computer, check with a professional. Don’t trust that your antivirus software is going to do the same, thorough job an expert can offer. Sometimes your computer isn’t fully safe until the operating system is reinstalled, but you can’t know that until someone can go in and see what the virus did and what remnants are still there, lurking.

Cybercriminals are growing more sophisticated and better able to design viruses that disguise their tracks. Avoid being an unwitting victim. A computer security expert can diagnosis when your computer gets a virus, or determine if there are strains on your device you don’t know about.

What Hackers Target In Small Businesses

by

Hackers today have many ways to attack small businesses and business owners. Many attempt to use technology to send malware, viruses, or phishing attacks; or use information to con owners and employees into handing over more information than they should.

One or more of these techniques can be combined with gaining physical access to steal from vulnerable firms. Identifying precisely how criminals target businesses and what they deem most valuable can help to protect from the most devastating attacks out there.

Remaining vigilant and informed is one of the most vital things you can do as a business owner to protect your assets and reputation.

Extortion

Different types of attacks tend to rise and fall in popularity. Fifteen years ago, computer worms were the most common attack that businesses faced. Security software wasn’t as advanced or as widely used at it is today. Computer worms were, at the time, an exceptionally low-cost and efficient way to inflict the maximum amount of damage for minimum cost.

Today ransomware has seen an unfortunate boom in popularity. This technology aims to encrypt the target’s files on their personal computer. This technique denies the victim access and charges a large fee in exchange for the key to retrieve the victim’s own data.

The attack has worked so often because it requires minimal effort and can be used again and again. Many businesses have no option but to pay because the data is worth far more than the ransom demand the hackers have made.

The best defense against ransomware attacks, in addition to strong online security, is an up-to-date offsite backup — one that is tested to work reliably.

Targeting Customer Records

One of the most important things for your firm to take care of is your customer data records. Records which include names, dates of birth, and other personally identifying details. These details are extremely valuable to hackers or criminals who, either use them personally or sell them on to someone who will.

Many regions have strict laws and guidelines about how this information must be stored, accessed and protected. Failing to follow these can result in severe penalties that could devastate any company.

Targeting Financial Information

Like personal information, a small business must take extreme care when storing customer financial information. Sensitive details such as credit card or banking information are a key target for hackers looking to steal money fast.

The impact on your business reputation following a breach of financial data will be severe and devastating. Even a simple mistake can require years of advertising and great PR to repair. Many firms have failed to recover after losing the trust of their customers.

Social Engineering

Most firms today run good IT security packages to protect against online attacks and other forms of malware. Attackers often know to take their methods offline to achieve the best results.

Whether posing as a supplier, customer, or interested party; attackers can seek to gain information that you may be less than willing to hand over to a stranger. Small businesses can often be used to gather information on vendors and suppliers they do business with in order to attack them too.

Be particularly cautious of the information you provide when discussing business with individuals you haven’t spoken to before.

Keeping Small Business Safe

Each of these targets and attacks are just some of the most popular and hard-hitting attacks out there now. The list is forever changing, and the methods we use to protect against them always needs to change too.

Some can be defended against with great security, backups, and software. Others, such as social engineering, need you and your staff to stay up-to-date and remain vigilant about the major attacks affecting small business today.

More Than A Virus, Common Malware to Watch Out For

by

The term “virus” is often used to describe many different types of infection a computer might have. Virus, when used as a blanket term, can describe any number of potential computer programs. What these programs have in common are they are typically designed to cause damage, steal data, or spread across the network.

Malware describes software designed to act maliciously on a personal computer. The name ‘malware’ is a shorthand for ‘malicious software’ and describes exactly what it is. A computer virus is a single type of malware that can cause harm to your PC, but it is only one of many.

Adware

Short for advertising-supported software, adware is a type of malware that delivers advertisements to your computer. These advertisements are often intrusive, irritating, and often designed to trick you into clicking something you don’t want. A common example of malware is pop-up ads that appear on many websites and mobile applications.

Adware often comes bundled with “free” versions of software that uses these intrusive advertising to make up costs. Commonly it is installed without the user’s knowledge and made excessively difficult to remove.

Spyware

Spyware is designed to spy on the user’s activity without their knowledge or consent. Often installed in the background, spyware can collect keyboard input, harvest data from the computer, monitor web activity and more.

Spyware typically requires installation to the computer. This is commonly done by tricking users into installing spyware themselves instead of the software or application that they thought they were getting. Victims of spyware are often be completely unaware of its presence until the data stolen is acted on in the form of fraudulent bank transactions or stolen online accounts.

Virus

In technical terms a computer virus is a form of malware that is installed inadvertently, causing damage to the user. A typical virus may install a keylogger to capture passwords, logins, and bank information from the keyboard. It might steal data, interrupt programs, and cause the computer to crash.

Modern virus programs commonly use your computers processing power and internet bandwidth to perform tasks remotely for hackers. The first sign of this can be when the computer sounds like it is doing a lot of work when no programs should be running. A computer virus is often spread through installing unknown software or downloading attachments that contain more than they seem.

Ransomware

A particularly malicious variety of malware, known as ransomware, prevents the user from accessing their own files until a ransom is paid. Files within the system are often encrypted with a password that won’t be revealed to the user until the full ransom is paid.

Instead of accessing the computer as normal, the user is presented with a screen which details the contact and payment information required to access their data again.

Ransomware is typically downloaded through malicious file attachments, email, or a vulnerability in the computer system.

Worm

Among the most common type of malware today is the computer worm. Worms spread across computer networks by exploiting vulnerabilities within the operating system. Often these programs cause harm to their host networks by consuming large amounts of network bandwidth, overloading computers, and using up all the available resources.

One of the key differences between worms and a regular virus is its ability to make copies of itself and spread independently. A virus must rely on human activity to run a program or open a malicious attachment; worms can simply spread over the network without human intervention.

How to Tell if Your Computer Has a Virus

by

Sometimes computers do wacky things that ring alarm bells and make us dive for cover. Next thing you know, you’re running scans on repeat and demanding everyone come clean about their browsing habits. Fortunately, not all weird occurrences are caused by viruses – sometimes your computer is simply overloaded, overheating or in desperate need of a reboot. Here are the tell-tale signs of a malware attack:

Bizarre error messages

Look for messages popping up from nowhere that make no sense, are poorly worded or plain gibberish – especially if they’re about a program you don’t even have. Take note of anti-virus warnings too, check that the warning is from YOUR anti-virus software and looks like it should. If a message pops up that isn’t quite right, don’t click. Not even to clear or cancel the message. Close the browser or shut down the computer instead, then run a full scan, preferably with a DIFFERENT scanner than what you have installed. After all, if the bug got past what you have installed, it probably won’t be detected the second time around! A great free malware scanner that you can use is Malwarebytes Antimalware available for free at the link below:

Suddenly deactivated anti-virus/malware protection

You know the best way to get past the guard? Send him for a coffee break! Certain viruses are programmed to take out the security systems first, leaving you open to infection. Most security software will warn you if your protection has stopped. If you reboot and your protections aren’t back on the job, you are more than likely under attack. Attempt to start the anti-virus manually through its control panel and you’ll know for sure.

Social media messages you didn’t send

Are your friends replying to messages you never wrote? Are you getting lots of ‘undeliverable’ messages in your inbox? Your login details might have been hacked and your account is sending out spam or scam messages. Your friends may now be tricked into giving up personal information or money. Change your email or social media password immediately, scan your computer for infections, and then advise your friends of the hack so they can steer clear!

Web browser acting up

Perhaps you’ve noticed your homepage has changed, it’s using an odd search engine or opening/redirecting unwanted sites. If your browser has gone rogue, it’s definitely a virus, usually one intended to serve you ads or steal your personal or financial details. Skip the online banking and email until your antivirus scans come up clear and everything is working normally again.

Sluggish performance

If your computer speed has dropped suddenly, boot up takes an eternity, or even moving the mouse has become a chore, it could be a sign that something is wrong. But, not necessarily a virus. Run your anti-virus scan and if that resolves it, great. If not, your computer likely needs a tune-up or repair. You may want to bring the computer in for a diagnostic.

Constant computer activity

You’re off the computer but the hard drive is going nuts, the fans are whirring, and the network lights are flashing like a disco? It’s almost like someone IS using the computer! Viruses and malware attacks use your computer resources, sometimes even more than you do. Take note of what’s normal when the computer is not infected so you can tell when something is out of the ordinary.

Why Do People Create Viruses?

by

 

You’d be right in thinking it’s hard to program a computer virus that can spread across the world in a flash – we’re talking days of constant desk-jockey nerd-work. So why do they bother? Well, it generally comes down to 3 reasons: Money, showing off their skill, or to simply being a jerk. While showing off or being a jerk is pretty self-explanatory, the money side is fascinating.

Here’s how people are making money with computer viruses:

Bank account theft: Virus creators are more than happy to help themselves to your bank details, sneaking in to grab your login details or credit card info. They can either transfer your funds away or use your credit card details to go on a shopping spree. Sometimes they’ll leave the fun to another person though, and simply sell your details to the highest bidder.

Ransomware: Rather than a financial snatch and grab, sometimes a virus will encrypt your files and demand money for the unlock code. Without a true backup plan in place beforehand, you’re at their mercy. You’ll be given very helpful information on how to pay, plus a firm deadline before your files are destroyed permanently.

Ad swappers: A cheeky technique, this is when they create a virus that either puts annoying ads on websites you visit, or places affiliate codes on pages so that when you buy something legitimately – eg, from Amazon – they get a percentage as a ‘referral fee’. Their kickback doesn’t make your purchase cost more and you may not even know you’re supporting their activities.

Bitcoin mining: You might have heard of digital currencies being used for payment, but did you know you can also earn them with your computer processing power? Unfortunately, ‘renting’ out your computer’s processing power means paying more in running costs than you’d make – unless you were very clever and sneaky, and used a virus to rent out other people’s computers.

Botnets: Certain infected computers can be remotely controlled to do whatever the virus creator wants. In this case, they’ll usually set the infected bot computers to overwhelm a target web server, like an e-commerce store. Sometimes it’s done as revenge, but more often it’s blackmail. The ‘Botmaster’ says “pay me thousands of dollars or I’ll crash your site during the biggest shopping day of the year.”

Account stealing: Subscription accounts like Netflix and Hulu are often hijacked, leaving you to pay the bill for someone else’s entertainment. But sometimes, virus creators go one step further with online gaming accounts. All those digital items that you fought so hard for (special clothing, weapons etc.) can carry real world value and be stolen from your account and sold on a black market. Yes, that’s cheating!

Finally, I have heard many of my customers say “I dont need anti-virus protection, I don’t have anything important on my computer”. Well, I would argue that a number of the reasons above are enough to want to protect your computer anyway. Even if you dont have any important files ON your computer, you most likley do have something valuable enough to steal, such as account passwords (so the bad guys can spam your contacts) or even just processing power.

How Much Could A Ransomware Attack Cost You?

by

How Much Could A Ransomware Attack Cost You?

Have you ever thought about how much your data is worth? Information is possibly the most valuable part of your business – there’s your client database, accounting software and inventory management, and of course, any intellectual property you may own.  When the ransomware, WannaCry, tore through the world recently, many businesses were suddenly forced to re-assess the value of their data: was it worth saving, and what would be the deeper cost of the attack?

Most ransomware attacks cost $150-$600 to get your files released, but that’s only IF the cyber-criminals honor the payment and actually give you the decryption key. Meanwhile, new client calls are still coming in and you may find yourself unable to operate with your systems down. Paying the ransom or restoring from an unaffected backup seems like a quick fix, but it doesn’t end there. There’s still the downtime involved to restore all your data – possibly days – and that’s a lot of lost productivity.  Plus, if word gets out that your data has been compromised, you may find confidence in your business plummets and your existing clients head elsewhere.  That $150 ransom may end up costing well over $150,000!

 

Prevent Ransomware Attacks on your Business

Keep your systems up to date: WannaCry took advantage of a flaw in older versions of Windows, one that was since patched by Microsoft. But to be protected, businesses had to be up to date with their patches AND be running a supported version of Windows. Delaying patches and updates puts your business at risk – we can help you update automatically.

Lock down employee computers: Very few staff will require full administrator access to your business network. The higher their level of permissions, the more damage a person can do – either accidentally with a whoopsie click, or by inadvertently installing malware. By locking down your employee computers, you have a better chance of containing a malware attack to non-vital systems. Our experts can design an access management plan that gives you best of both worlds: flexibility PLUS security.

Educate your workplace: Most employees believe they’re being cyber-safe but the reality is quite different. Many malicious links and embedded malware have become hard to spot in an instant – which is all it takes to click and regret. We can work with your staff to establish procedures around checking links for authenticity before clicking, awareness around verifying the source of attachments, and the importance of anti-virus scanning. We’ll help get the message through!

Have a solid backup plan: When ransomware hits, a connected backup = infected backup. Unfortunately, synced options such as Dropbox immediately clone the infected files, rendering them useless. The only safe backups will be the ones both physically and electronically disconnected, with systems designed to protect against attacks like this. Our experts can set you up with a backup system that makes recovery a breeze.

Be proactive: The best way to avoid the financial cost of a ransomware attack is to prevent it from happening in the first place. Remember, many businesses were able to watch WannaCry from the sidelines, completely unaffected and seizing opportunities while their competitors were down.

Our managed services can help protect your business against the next cyber-attack. 

WannaCry Ransomware Explained: Is Your Business At Risk?

WannaCry Ransomware Explained: Is Your Business At Risk?

You’d be hard-pressed to miss last week’s biggest headline, the WannaCry cyber-attack sent shockwaves around the globe. Businesses of all sizes and even police departments found themselves crippled without warning.

Among the most prominent victims were many NHS hospitals in the UK, affecting up to 70,000 individual devices such as essential MRI scanners and blood-storage refrigerators. But by the time it hit the news, it was too late – either your system was protected, or it was infected. Here’s how it all went so wrong.

What is WannaCry?

The WannaCry cyber-attack was a type of malware (the collective name for computer viruses & bad juju) called ‘ransomware’. Just like the name suggests, it’s actually a demand for money. Like all ransomware attacks, WannaCry encrypts your files and holds them hostage until you pay. In this case, the price was set at $300, payable with internet currency Bitcoin, and you had 3 days to pay before it doubled. If you didn’t pay, the ransomware threatened to delete your files permanently. It’s yet unknown how much money the WannaCry hackers have earned with their latest attack, but you can be sure plenty of people have paid the ransom. Even the FBI recommends paying the ransom, especially if the ransomed files are of a sensitive nature or weren’t backed up.

 

How It Spread So Fast

It seems WannaCry may be a ‘computer worm’ that self-replicates and spreads, rather than a phishing attack that needs to be activated with a click. So far, no common trigger has been identified, as is normally the case with phishing links. WannaCry moved rapidly from system to system, spreading out through the entire network, including all connected backups and storage devices. At the same time, it spread out to infect other networks, who then spread it further, and so on. Given the nature of the internet, it was everywhere within hours.

Why Some Businesses Were Safe

WannaCry could ONLY infect systems that have fallen 2 months behind in their Windows updates. This is because it was created to take advantage of a specific vulnerability in Windows, one which Microsoft patched months ago. Without that patch, the ransomware could waltz right past the firewall, past the anti-virus and directly into the system (the NHS were reportedly running Windows XP – no longer supported). Those running Windows 10 or a fully patched, recent version of Windows were completely unaffected – the virus literally had no way in

It just goes to show the importance of staying up to date. We haven’t seen a second spike in WannaCry attacks yet, but that doesn’t mean there won’t be one. A quick update could protect your business from weeks of downtime and lost revenue, making attacks like this a non-issue.

With our managed services, we can make sure you stay up to date – and protected. Give us a call today at 515-422-1995
