Today I visited a dubious site with an ad that attempted to open Adobe Acrobat. I immediately closed the window as soon as the splash screen appeared, but the damage was done. My computer started to lag pretty badly and checking Task Manager revealed IEXPLORE.EXE was open and using as much memory as Firefox. I closed everything and restarted, sure enough Internet Explorer showed up in the Task Manager again and now I was getting popups in both it and Firefox. IEXPLORE.EXE continued to show up again after repeatedly closing it from the Task Manager.

I searched on Google and ended up here, registered and searched the forum for anyone with similar problems, ended up getting Malwarebytes' Anti-Malware. I repeatedly ran it and restarted my computer, managed to bring down the number of infected items from 29 to 3, but can't get it completely clean, and IEXPLORE.EXE still opens on it's own. Also, after the first scan and restart this started poping up after logging in:

RUNDLL
Error loading C:\WINDOWS\System32\yevilido.dll
The specified module could not be found.

Everything I have is really old, I'm still using SP1, Firefox 1.0.7, IE5, Acrobat Reader 5.0.5, and the only anti-malware I had was Norton 2002, and I hadn't scanned my computer in ages before now.

Here's the log of the most recent MBAM scan:

Is my system beyond hope, or am I just beyond hope?

To protect yourself from these types of attacks it is suggested that you disable javascript from running within PDF documents. For the vast majority of users, this will have no affect on the reading of legitimate PDF documents. It will, though, give a warning when a PDF document is trying to execute javascript and you can then decide if you would like to allow it. To protect yourself, open Adobe Reader and once it is open, click on the Edit menu option and then select Preferences. When the preferences screen opens, click on the javascript category. Then uncheck the checkbox labeled Enable Acrobat javascript. When done, your screen should look like the image below. Then press the OK button to save your settings.

Ugh, I shouldn't be such a packrat. The program erroring half halfway through the first try didn't help.

This got rid of the "Error loading C:\WINDOWS\System32\yevilido.dll The specified module could not be found." message, but I caught IEXPLORE opening again. Seems to randomly happen when I use Google or click on links.

Going to the next step and using ATF and SAS now.

Also, seems my Acrobat Reader is so old there's no Javascript option under Preferences. Guess this means it's always on until I upgrade it and turn it off?

Used ATF with no problem, but left SAS to run overnight, suddenly woke up just now to find the affected computer off. Feared the worst and tried to turn it on, it refuses to boot, even into Safe Mode, it just hangs on the black screen after selecting "Microsoft XP Home Edition" after selecting "Safe Mode".

Guess it's dead?

Should I try reinstalling XP?

Will I be able to get any of the files or programs from the computer?

It sounds like the MBR got hosed. If you have an original XP CD you can run the Recovery Console and repair the MBR:

Should I try reinstalling XP?

That is always the best thing to do

Will I be able to get any of the files or programs from the computer?

You run the risk of reinfecting the computer. We didn't get everything
