Time passed, and ignoring it became more annoying then trying to fix it, so my first try was to download the installer from another computer onto an SD card and then bring it to my computer and use it there.

After some rage grunts I decided to just wait and ignore it. I found the 'Fix for Failed Update' and tried it, but I use a wireless keyboard and mouse so I couldn't get into safe mode. Cursed, shut down, restart, cursed some more, and then came to the forums. I tried the chat client and my computer froze trying to load it. The rest of the webpage was loaded fine, but just that one part would not load. I logged into my account, clicked download, clicked agree, clicked download, and IE8 told me that it could not display the webpage. My first try was to reinstall McAfee, as the error advised. It became clear that I would have to do something to fix it, and that is when things started to get weird. I wasn't too worried at first, since that error popped up from time to time, and it had always just disappeared on it's own before, but this time it stayed.

After several scans, it seemed like the trojan was gone, but then McAfee started giving me the failed update error.

Despite McAfee, I downloaded a trojan a few days ago.
