Exterminate It! Antimalware


Known threats:700,085 Last Update:March 01, 12:55


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.

Spyware is designed to gather data from a computer and transfer it to a third party without the consent or knowledge of the computer’s owner. This includes collecting confidential information (passwords, credit card numbers, PIN numbers, etc.), monitoring key strokes, gathering e-mail addresses, or tracking surfing habits. Such resource-consuming activities slow down the system and generally impact the computer’s performance.

“Spyware” is an umbrella term for a diverse group of malware-related programs, rather than a clear-cut category. Most spyware definitions apply not only to adware, pornware and ‘riskware’ programs, but to many trojans as well.


Of all trojans, backdoor trojans pose the greatest danger to users’ PCs because they give their authors remote control over infected computers. They are downloaded, installed, and run silently, without the user’s consent or knowledge. Upon installation, backdoor trojans can be instructed to send, receive, execute and delete files, gather and transfer confidential data from the computer, log all activity on the computer, and perform other harmful activities.

Be Aware of the Following Backdoor Threats:

Delf.cg.Server, MiniLD, Lisbon, Tobort, Viper.
