About two days ago, I noticed that my internet browser (Firefox) kept crashing. I reinstaled it and optimised its memory usage, but that didn't help. When I switched to IE, the same thing happened. I rebooted the computer, and this time none of the normal applications (Skype, MSN, McAfee 'active' icon) loaded correctly. The computer also seemed to be going a lot slower than usual.
I am using Windows XP, Home Edition (2002), SP2. I tried to update to SP3, but on restarting the System menu still tells me I'm running SP2.
I downloaded FreeXPpro to make sure that a memory leak wasn't to blame, and it indicates that at least half of my RAM is free most of the time.
Then, I downloaded ProcessExplorer to check to see if any of the system processes weren't what they should be (everything seemed fine).
I tried to run McAfee, but the scan went so slowy that about 7 hours later at 70% the computer locked up. It didn't find anything in that time.
Then I downloaded Clean40 to clean my temporary files.
Next I downloaded the latest version of a Malwarebytes. It crashed when I tried to update it, and went very slowly otherwise. I decided to run it in Safe Mode, and it discovered 9 registry keys were infected with WebDir and MiniBug.
However, on restarting my computer, the programs still won't load correctly on startup, windows update / Malwarebytes update doesn't work and I still get random crashes.
I'm really stuck and I don't know what to do to get my computer back to normal, so any help would be greatly appreciated.
