There currently is a major outbreak of malicious, fake, viruses appearing in emails and on websites. Please do not click on anything that indicates an update is required or recommended. While there are legitimate updates you will see from time to time, the majority in the wild today are very dangerous. If in doubt on what to do, "pull the power" from your PC and give us a call immediately.
One we are seeing often is the Fake "Microsoft Security Essentials" that looks very similar to an actual Microsoft update window. Remember this if nothing else, "if in doubt, don't click". Below are a few pictures of what a malicious, fake virus may look like. Be assured, if you click on any of these anywhere in the window, you are giving your permission to destroy data and terminate any type of legitimate protection you may have on your PC. Please be safe and exercise caution any time an unsolicited window appears on your PC.
