Exterminate It! Antimalware


Known threats:700,086 Last Update:March 16, 12:51


Just want to let you know this is a great product. We bought it but it didn't get rid of the CID popups. We let you know and within 2 days we had a fix. Now we are CID free. My husband says this is the best money we've spent on a software product in recent years. We had been trying for 2 years (on and off) to get rid of these annoying CID popups and now we are CID free. Highly recommend Exterminate it. My husband says and I quote I am a believer!

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.
