Exterminate It! Antimalware


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


Hello, bought a license for your antivirus tool and I must say it was totally awesome! It cleaned TDSServ trojan which was a real pain in the ass for the last 8 months and it also found and killed Virtumonde together with all its files and a few other low level infections. I was already thinking about formatting and losing tons of information when I found your tool on the internet.

Thanks and please put this message where people can see 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.
