You may be right.

microsoft antivirus is this: http://www.2-spyware.com/remove-microsoft-antivirus-has-found-critical-process-activity-on-your-pc.html

BTW, take no action on any advice on this website. Wait for essexboy to come back. This link provided just fyi.

[EDIT:] Site recommends downloading and running SpyHunter. Do not run this program, not worth the trouble, and it may make things worse.

Microsoft is the vendor of this program: http://windows.microsoft.com/en-us/windows/security-essentials-download

Not the same thing.

Again, I’d wait 'til essexboy comes online again, to see what he says, as you are in the best of hands here.
