Watch out for these Computer Viruses!


Be extremely careful of these viruses. They can completely destroy your critical business data and close your business quickly. We have seen cases where these viruses have spread over an entire network and caused serious damage. In one instance, the Cryptolocker virus wiped out a business client’s server, workstation and backup drive.

What are these viruses? What do they do?
Typically, they infect a server or workstation and encrypt all of the files and data on it. You will see a popup that your data has been locked up and you need to send a payment to receive a password to unlock it. Usually, you are given a time period to respond. Unfortunately, if you send a payment it is unlikely that you will receive a password. Instead, we have seen cases where the virus creators will even ask for more payments. Once your data has been locked, it is impossible to find the password. Usually, it is held on external servers that are very hard to track down.

How do you get these viruses?
Usually, the Gameover Zeus and Cryptolocker viruses come through email links and attachments. Once you click on an attachment, the virus will begin to run and install itself. For this reason, it is very important that you do not open any links or attachments from unknown or suspicious senders.

What should you do if you see a message about your data being locked?
The best thing to do is to turn off your business computer immediately. Also, you can disconnect it from the Internet. The sooner you do this, the more likely your data will not be lost. We have seen cases where this message has popped up and clients have immediately turned the computer off. We have run some scans and removed these viruses. Fortunately, our business clients’ information has not been affected.
