My colleague Henry asked to scan his USB he suspect a virus is lurking in there. I have both Kaspersky and MSE running in real-time. MSE detects and Kaspersky snoozed!. It was Win32/Vorus.CV And MSE cleans it. I am confident with this product. Since it’s gonna be free, i am a full supporter and advocator of MSE. Use it try and have a trouble free computing environment. PS> Want a copy of MSE? I can give it to you but you have to write to me for with your email addy.
