Testimonials

Dear Jean, Thank you for your response. I had a Windows 2003 Server down because of the USBroot trojan. I purchased Exterminate It! and it corrected the problem. I am very pleased with your product! I’m going to purchase it for other workstations with problems in our company.

Trojan

A trojan is a program that is disguised as legitimate software but is designed to carry out some harmful actions on the infected computer.

Unlike viruses and worms, trojans don’t replicate but they can be just as destructive.

These days trojans are very common. Trojans are divided into a number different categories based on their function or type of damage.

Be Aware of the Following Trojan Threats:

URLHook, Deletall, Bancos.GOM, Pigeon.AVHW, Win32.PSW.Barrio.

Backdoor

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:

FG.Server, Kaitex, Mordor, Singularity, Chameleon.
