Cleaning

These instructions are intended as a useful process for cleaning computers infected with malware and protecting them from future problems. This process is in no way endorsed or guaranteed and I make no claims about its reliability. These steps are good for remediation, but there is no substitute for preparation and responsible computing practices.

The Short Version (Preparation)

  1. Turn on Windows Firewall to prevent intrusion
  2. Turn on Automatic Updates to block security holes
  3. Install/update/run anti-virus software regularly (should already be installed, see the long versions for suggestions)
  4. Install/update/run anti-adware and anti-spyware software, including the following (which each have a preventive element)
  5. Install Microsoft Updates http://update.microsoft.com

The Long Version (Remediation)

  1. Turn on Windows Firewall to block unwanted network or Internet traffic
  2. Turn on Automatic Updates to patch security holes faster in the future
  3. Disable System Restore, as infestations may regenerate themselves from the restore points
  4. Uninstall known spyware or risky software. If a program is questionable, try a web search for reviews or check a rogue anti-malware guide for malicious or useless tools
  5. Install/update/run only one good anti-virus program, such as:
  6. Install/update/run anti-adware and anti-spyware software, including the following, in Safe Mode and then in a regular boot until both read clear
  7. If applications do not install, run Web-based scanners, like
  8. Repeat any scans above that gave results, to assure removal.
  9. If the infection still remains, use the following to obtain detailed system status
  10. If there is a specific suspicious file to check (i.e. an expected but suspect email attachment), examine it at Virus Total
  11. Install Microsoft security updates
  12. If the infection still remains at this point, running scans from outside Windows may work better. To do this create a bootable environment with scanners like those in the Ultimate Boot CD for Windows (UBCD4Win) or Hiren's boot CD. Remember to check licenses to be sure that software used is legitimate.
  13. If the infection persists, back up critical data, completely erase the hard drive, and reinstall Windows. See the Short Version (Preparation) above to help prevent future infestations.

Network/hardware issues

  1. If the network is not working and all settings appear correct, run Winsock XP Fix
  2. To identify devices better than Device Manager, try

System optimization

  1. Remove unneeded programs(Start > Control Panel > Add/Remove Programs)
  2. Run Disk Cleanup(Start > All Programs > Accessories > System Tools > Disk Cleanup)
  3. Find and remove large unneeded files easily with Space Monger
  4. Run Disk Defragmenter(Start > All Programs > Accessories > System Tools > Disk Defragmenter)
  5. Remove unneeded startup entries(From System Tray or via Start > All Programs > Startup)
