Go to this link and you will be able to download and install all the security programs you need to scan and remove your problems if you have them.
And before the Applebores jump on here with the “Just buy a Mac crap”, remember these things do not jump out of thin air and infect your computer. You are letting them get on your computer with your computing habits. These include opening spam e-mails (even those from friends), going to websites that are flagged by your anti virus program as being dangerous, and the biggest one I still see is file sharing through Limewire, If you have this program uninstall it and use Torrents, but scan all downloaded files before running.
Never ever run two anti-virus programs on your computer. If you are running McAfee or Symantec, you are better off with Avira AntiVir Personal Edition (free) or AVG Free version.

Gad, I can’t tell you how many times I’ve worked on a home computer that is running slow....only to find out they’ve installed Limewire.
I usually tell them the fastest and best way to fix it is get out the recovery CD, format and reload.
I then tell them not to allow their kids to install Limewire.
Yeah, I know, I can scan and remove, however, from a cost standpoint, running the recovery CD is quicker, and I tend not to get a call back telling me they’re having problems again. At least, not until the kids install Limewire again.
