I believe that I have a virus that is disabling my antivirus protection. I had mcafee, which i deleted because I thought there was an issue with McAfee, and now I can't download it again. It says that the page cannot be found. I have tried to install other antivirus software from the internet, and the same thing happens. I have downloaded what I could in an attempt to 'find' this thing, but everything I have is coming up clean. Any help would be greatly appreciated! Please help me if you can!!! Thank you in advance for your time.
