Clean an Infected PC

Computer infections can cause major computer errors, such as pop-ups, audio voices, and an overall slower computer. Some computer infections are easy to remove, while some are almost impossible.

Steps

  1. Backup files that you know are safe onto a disk or other external media source if possible. Do not use system restore since when you create a restore point the viruses file's are also backed up.
  2. Turn off the system restore and delete all of the restore points. That way you will be sure once yo remove the virus it will be off your computer.
  3. Download free anti-virus and anti-spyware software. Some good choices for anti-virus software are Bitdefender Free Edition, Avast Home Edition, and Avg Free Edition. Only have one of these installed at a time and make sure to update them before you run them. For anti-spyware software you can download Ad-Aware Free Edition or Spybot Search and Destroy.
    • Note: You might have to download your anti-virus and anti-spyware software on a non-infected PC then put the file's on a disk and bring them to the infected PC.
  4. After installing your anti-spyware and anti-virus software update them and run a scan with them. Make sure you write down the name of the infection it finds before you remove them.
  5. Restart your computer in safe mode. Use the (F5 or F8) keys depending on which OS you are running.
  6. Repeat the scanning step to make sure your PC is clean
  7. If your computer is still infected download and run Trend Micro's Hijack this. Copy and paste a copy of your Hijack This log to one of the forums the Hijack This website recommends.
