Bad ware and other computer nightmares to avoid.

[DSL]

When i web search for some websites sometimes i get hit with an
( Adobe Reader license agreement popup window ) when i try to close it
it will install some nasty addware virus program that will take over your system and turn everything upside down! even when i click no on the
adobe reader it will install it any way and you can't get rid of it without
formatting your hard drive!. if you know a removal tool that can get rid of that bad apple without formatting my hard drive or anyone else.
i don't have the virus now but its out there and can be a pain in the ass.
thanks.

i also get a fake virus window saying that your system is under attack! and now scanning.

i do have McAfee security center too.
