There are viruses on my computer. I am not too sure how to fix it. I tried reading some of the solved posts here to see if I could do it myself. When I try to download AVG antivirus I keep coming up with an error when I try to install it.(wondering if this is an effect of the virus). Also I have xp security on here now(but it's unregistered/useless). Please help if possible. Thank you for your time.
