I believe my computer has a rootkit on it. Any ways I could get rid of it?
Erase the hard drive and reinstall Windows.
;)
More seriously, though. This page (http://www.techrepublic.com/blog/data-center/rootkits-is-removing-them-even-possible/) seems informative. The #1 thing that you want to do is make sure that any software you get is from a reliable source. Don't just pick up the first app you see; look around a bit and get something that's recommended by people who are in the know, and always look at reviews from multiple sources before you install anything.

Worth trying this free download and see if anything is found.
My family has Kaspersky too.
So, checked this out, and I don't think I actually had a rootkit. Wouldn't be surprised if I had had one though, with all the scum my computer has gotten off the Internet....
