XP Defender Pro Analysis and Removal
XP Defender Pro belongs to the family of Trojan:Win32/FakeRean infecting users running Windows XP. It is installed by a trojan dropper file which is capable of installing a rogue with any one of the names from its stable, with a matching fake Windows Security Center.
It uses any one of the following names: XP Smart Security, XP Smart Security 2010, XP Antimalware 2010, XP Antimalware, XP Security Tool 2010, XP Internet Security, XP Defender Pro, XP Security, XP Security Tool, Antivirus XP.
A rogue security software such as XP Defender Pro belongs to a family of software products that call themselves as antivirus, antispyware or registry cleaners and often use deceptive or high pressure sales tactics and deliberate false positives to convince users into buying a license/subscription. They are often repackaged and renamed. They do not actually remove malware instead many of them add more malware of their own. Users should not fall for the fake alerts and must not buy the scareware. They need to be removed immediately from your system.
When ran the Trojan drops a hidden, system file named ave.exe in the %AppData% folder which in turn drops a hidden, system file named y7V11 in multiple directories including %AppData% and %Temp% folders. You may need to enable viewing hidden folders and protected operating system files in folder options control panel to see them. The scareware modifies the registry so that:
- The scareware executes (ave.exe) every time a .exe file is run, an innovative way to autostart with Windows or to restart when killed via TaskManager. It also makes it difficult to install and run security programs.
- Makes Internet Explorer as the default browser and promptly hijacks it to display a scare message whenever it is run.
- Hijacks Firefox normal mode and Firefox safe mode (no addons), so that the scareware starts whenever Firefox is run and a fake alert is displayed.
- Disables Windows Firewall
- Disables genuine Windows Security Center notifications
