Hi Dean,
Considering you do not have an XP CD, the best option might to be manually clean up everything..
Remove all users accounts bar one, this in turn will delete all their documents, music, etc.
Also, go through the Add and Remove programs and delete everything that is not needed. I'd guess you would be able to remove most programs that are installed apart from applications like Office, DVD Player Software, Windows Updates etc??
Once done run the items listed below to make sure there is no Malware on the system.
- Malware is software designed to infiltrate or damage a computer system without the owner's informed consent.
It is a combination of the words malicious and software.
The expression is a general term used by computer professionals to mean a variety of forms of hostile, intrusive, or annoying software or program code.
- Required Cleanup Steps
- Disable the Spybot Search & Destroy TEA TIMER if you use it and if it is enabled
- Run a Temporary file and cache cleaner (ATF)
- Run 2 Anti-Malware scanners (Listed Below)
- Run an Online Anti-Virus / Anti-Malware Scanner (Listed Below)
- Clear out old System Restore points
- If continued Malware type activity is present you may be asked to post a TrendMicro™ HijackThis™ Log file, do not do so unless requested.
The reason to run multiple scanners is to ensure that no single scanner is missing something.
The time it takes will vary depending on your system and your internet connection speed.
Typically the SUPERAntiSpyware and Malwarebytes scanners will take between 10 to 90 minutes.
The ESET online scan should take between 1 to 3 hours.
In most cases, these scans will suffice to clean and disinfect your computer.
Heavily infected systems or slower PCs can take much longer to scan and clean.
