After scanning my computer many times using big name anti-virus and malware programs I still had several problems. Finally Exterminate It found multiple infections from NetSky. I sent Exterminate It a sample and the next day I received an e-mail instructing me to update and rescan. After following the instructions ZAP the worm/trojan was gone. My computer seems to be completly back to normal now. Good Job Exterminate It!

Why Is It Important to Remove Malware Files?^

It is imperative that you delete malware-associated files as soon as possible because they can be used - or are already being used - to inflict serious damage on your PC, including:

  • Disrupting the normal functioning of the operating system or rendering it completely useless.
  • Hijacking valuable private information (credit card numbers, passwords, PIN codes, etc.)
  • Directing all your Web searches to the same unwanted or malicious sites.
  • Dramatically slowing down your computer.
  • Gaining total control of your PC to spread viruses and trojans and send out spam.
