There is a particular malware hitting many systems and has been for a few months now. Some of my clients have unknowingly allowed this malware onto their computer because it looks like a legitimate anti-virus upgrade request.
Please be aware of this and if you see a "pop up" asking you to install or allow the Anti virus 2008 or Anti-virus 2009 to install on your system do not let it.
If you are one of the unlucky recipients of this malware and it has indeed infected your system and just will not go away there is a removal tool that works. It called malwarebytes and it is a free download.
It has saved us a lot of time and our clients a great deal of money and hartache.
Here is the link.
If you have any issues with it post them here or email me and I will get you squared away.
