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.
This is a mass-mailing worm with backdoor thus allowing un-authorized access to the infected system.
It spreads by mass-mailing itself to e-mail addresses harvested from the local computer or by querying on-line search engines such as google.com.
The IP address that YOU are getting from Internet Service Provider (ISP) for YOU personal computer is on some major blacklist, like SpamHaus.
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.

This infection has morphed recently to show the above screen right after you login, and if you close it, may cause your computer to reboot. This effectively ransoms your computer so that if you do not purchase it, or use a guide like below to remove the infection, you will not be able to use your computer properly.

If you are infected with Desktop Defender 2010, then please do not purchase the program. If you have already purchased the program, then we suggest you contact your credit card company and dispute the charges while explaining that the program is fraudulent. To remove this infection and any related malware, please use the removal guide below.
