MBP major virus I think I am sure I have got some virus(s) in my Mac book &amp; I have no idea what to do about it. I download torrents on a regular basis. When I am in Safari, every time I click a link of any kind a new, extra tab opens that has nothing to do with what I have clicked. Usually it opens to mackepper or similar type "junk sale" web site.

Help!
This sounds like you're experiencing MacKeeper and similar website ads.

What worked for me is a Safari extension called AdBlock Plus.
