There are several free anti-virus solutions you could try. Avast!, Avira, and AVG all have a free AV, available from their websites or from C-Net's download site.
Problem is, installing an anti-virus over top an existing infection. This can make the infection hard to find, or even make the AV not install correctly. While it is very important to get an anti-virus on your system yesterday, I would say at least run the free version of Malwarebytes first to try to get rid of any existing infection before you install whichever resident protection you choose.
I believe I have a keylogger or some other type of virus on my computer.
One of my youtube accounts has been hacked and the password changed. I think this was a keylogger because other people on youtube were getting hacked by this as well.
But then last night I was talking to some friends on skype (IM-ing) and my messages were getting delted, and edited, and I wasn't doing this. This makes me think he can see my screen and do whatever he wants. I'm not sure if a keylogger can do this.
Is there any way to track/remove this virus so I can get rid of it?
I currently don't have a virus software because my Norton expired so if someone could find a free one it would be helpful, because all the free ones I have found never worked.
I am on windows vista 32 bit, if that helps at all.
