To try and make a long story (sort of) short, I stupidly clicked on a link I shouldn't have, and managed to get myself infected. I ended up purchasing and installing Bitdefender plus 2012. Finally my scans came back clean, but I was still getting random firefox pages opening, etc, so I decided to try a system restore, this morning. Everything seems to be grand now, aside from having to repair the programs that were affected (my old antivirus icons came back, as well as games that had been uninstalled, etc). The problem now concerns my Bitdefender.
I downloaded and ran the uninstallation tool to remove it, then redownloaded and reinstalled. I've done this three times now, and everytime, I end up with the same window popping up:
bdagent.exe - Unable to locate component
This application has failed to start because mfc100u.dll was not found. Re-installing the application may fix this problem.
I've also had this error come up saying it couldn't locate seccenter.exe.
HEEELP??? Aside from uninstalling and reinstalling, I really don't know what else to do!
