Have you considering wiping it and using a linux distro instead? It would be better suited to the older hardware I expect.

Download, update and run Run Malwarebytes' and Hitman Pro, although you may have some infected OS files that can not be removed...

Best of luck.

Not the answer you want to hear but a re-install would definitely be the best way to go - even cleaned up it doesn't sound as though it's going to be a trustworthy machine. Also if it's that full of crud then a fresh install is likely to improve performance somewhat, especially with limited RAM.

Is it a recognised brand? You might be able to get system recovery disks from the original manufacturer.

The other thing to check for is a system recovery partition on the hard drive.

Malware Bytes ...

Once you have it clean (ish) recover the various keys for XP &c, and do a re-install from a borrowed set of disks.

MHC,

"...recover the various keys for XP &c, and do a re-install from a borrowed set of disks."

Could that be done after the cleanup by running SFC.EXE/SCANNOW with any XP installer cd disk in the drive?

If re-install is the plan, is there any point in cleaning it beyond checking for MBR viruses?

If the OP needs to recover keys for XP or anything else then it may be necessary.

May need to download and run RogueKiller also if any running rogue processes prevent the installation and scans by MalwareBytes/Hitman Pro.

Is there a "COA" sticker on the case somewhere that includes the OEM key for XP? if so, all you need is an XP OEM (Probably XP Home) installation CD.

If you can't reinstall from scratch, use another machine to download the Kaspersky Rescue ISO and burn it to CD. Boot the affected PC from this CD, do a full scan and fix everything that's found.
The Falcon Four boot CD will allow you to update and run MBAM, SAS and others from it.
Be warned that whatever you use, if operating system files are infected and untreatable, you will need to reinstall anyway.

OK, although I'd expect the key to be on the Microsoft sticker on the machine if from a recognised brand or reputable OEM.

Hello Steve,

Is this computer a big brand name computer?

I'm guessing from the specs that the computer dates back to around 2000-2002, in that period was the time the manufacturers didnt supply a restore disk. They had a hidden restore partition on the hard drive, which would format and install a fresh copy of windows on the main part. Can you check the computer to see if you have a restore partition.

Also, how do you know the computer is full of malware and virus's if you dont have malware and virus software installed telling you?
