Defense Center is a malicious program that is related to the notorious rogue program Protection Center. It tries to trick users into paying for a license to its ‘full’ version. Defense Center gets installed on user systems via Trojan viruses that get downloaded from malicious websites which claim to contain malware scanning services. Once installed, it immediately blocks any legitimate security software that the user may have installed on their computer. Defense Center also runs endless fake virus scans and reports that the user’s system is infected with dangerous malicious software. It also displays fake warning pop-ups from the Windows taskbar. Meanwhile it constantly requests the user to upgrade to the ‘full’ version of Defense Center by paying for a software license, claiming that the currently installed ‘trial’ version is incapable of properly removing the detected false ‘threats’. However, no user should allow him to be tricked into buying this software, as the ‘full’ version of Defense Center is just as incapable of cleaning a computer system as the ‘trial’ version is.

It is extremely important to initiate Defense Center removal as soon as you find any signs of it being installed on your computer. In order to remove Defense Center properly, it is needed to stop its processes, unregister its DLLs, delete its files and folders and remove its registry entries.
