Difficulty Removing Personal Antivirus!

I got the Personal Antivirus application to hack into my computer last night. This morning I tried using multiple programs, (including MalwareBytes' Anti-Malware). I did this in Safe-Mode with Networking, it seemed to do the trick. As it rebooted, it booted up normally and I wanted to do a Full Scan just in case to make sure everything was removed. During the scan, I noticed that the PA has came back, but I was quickly able to delete the file. By the time the Full Scan was done, an additional ~46 files were infected. So I pressed to have it removed, it had the computer start. Here's where the problem starts. Now most of all the .exe files WILL NOT work. Including, firefox.exe, mbam.exe, C:\Windows\system32\rundll32.exe, etc. Is there anyway to fix this now? I am trying to run on safe-mode but unsure of the next steps.

Thank you for your help.

Edit: Ok, so putting the computer back into Safe Mode with Networking, the .exe files continued to not work. It would open up a box saying Open Programs With.. and if you'd match the program, it would work. I got the MBAM to work again, did another quick scan, found more infected files, rebooted, and the .exe files now seem to work properly again. However, it seems that my computer has taken a significant toll in slowing down. Can the computer still be infected?

Probably is still infected.

Sorry to bump this, but I've been away for college and left this computer home to collect dust. But the unfortunate thing is that during break, it's the only computer available and I realize that it's VERY slow. It refuses to even turn on, or it restarts as soon as it hits the welcome screen. Can this still be the likely effect of the virus? Things like this have never happened before my computer was infected. I was thinking of reinstalling the hard drive (but I would have to purchase a new CDROM drive since it's broke, and not sure if it's worth it). Would it work fine if I was able to reinstall it?

Well, I would say it's worth getting a new CDRom, they don't fail too often and last at least a few years.

Formatting would fix everything, formatting it means going back to the basics, Windows only.

Great, thank you. Wasn't sure if it's probably just the computer getting old (it's not even that old, maybe soon 3 years?) But just that after the damn virus, everything got shitty.
