Exterminate It! Antimalware


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


Over the past six months I had a lot of trouble surfing the Internet and working on my PC. I tried different free and pay antivirus software, but they were all of little help. I scanned with Exterminate It! It turned out that my computer was infected by five different viruses and Trojans, and your tool found them all! Now my PC is perfectly fine. I am really impressed.

Exterminate It is also very simple to use, which is essential for computer novices like me. I like it so much that I recommend it to my family and friends.
