Testimonials

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.

  • 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.
