Desktop Defender 2010 is a rogue security program from the Contraviro family. When installed this program will be configured to start automatically when Windows starts and will then create fake malware files that will be detected during the program's scans. Desktop Defender 2010 will not, though, remove any files that it states are malware until you first purchase the program. In reality, the scan results from this program are false and Desktop Defender 2010 is not actually finding any infections. Instead it displays the same scan results regardless of the computer that is run on. Therefore, please do not act upon anything that this program states are infections as it is possible you may delete a legitimate program.
While Desktop Defender 2010 is running you will also see security alerts appearing on your desktop. These alerts will include messages stating that there is spyware running, that you are at risk for losing data, or that your computer is sending SPAM. An example of one of the alerts you may see is:
You have been infected by a proxy-relay trojan server with new and danger "SpamBots".
You have a computer with a virus that sends spam.

Your computer has been used to send a huge amount of junk e-mail messages during the last days.
You IP will be marked in the Police log file as mass-mailing spam assist.
Upgrading to the full version Desktop Defender 2010 it will eliminate the majority of Spam attempts.
