Dear Matt and Exterminate it,

Thank you so much. This seems to have fixed the problem. Wow. That virus was in there pretty deep. A*G didn't even identify it. S****t would just freeze up when I tried to run it. But the update from Exterminate It, removed it.

Again, thanks.

Kind Regards,
Rev. Mel C. Montgomery

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.

Be Aware of the Following Spyware Threats:

Free.Keylogger.Common.Components, Computer.Spy, ESP, Bancos.Variant, Small.ad.


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:

AnonIRC, Perl.Backdoor.RevTunnel.A!Trojan, SB, Zhengxi, Zdemon.

Downloading and Installing Freeware or Shareware

Small-charge or free software applications may come bundled with spyware, adware, or programs like Der.Spaeher.
