Specs: Windows XP, 256 MB
Im pretty positive those are the correct names. AVG reported them after a scan. They were also reported by AVG when I turned on my computer. the first time (after the scan) AVG fixed the problems. However, the second time, it could only remove one and said that the others were in files crucial to the system running or something like that... If it helps my computer is a 32 bit Dell 8200
1.89 GHz
256 MB of RAM
Service Pack 3
I also repartitioned it about 3 months ago (it was a "zombie" or so to speak...) and did a system restore back to March 3rd yesterday to get rid of MS Removal Tool. I know this computer is slow and ancient but I wanna keep it running for as long as I can.

Thank you for your time and help! :D

1: Go to Control Panel > Programs and Features and uninstall Malwarebytes.
Next redownload Malwarebytes but rename it before you download it to your desktop. As you are in the process of downloading when you get to the point that the "enter name of file to save to" box appears, in the "filename" slot, rename mbam-setup.exe to something.exe, then click Save.
