Sometimes broken softwares, viruses, adwares and spywares sometimes tend to make things worse for you by disabling the Task Manager so that you cannot access it in anyway. Sometimes it is also done by network adminstrators so that you do not meddle with the precious company hardware

The only solution, which in fact is very simple. Just Click on Start > Run > and type the following or copy paste it.

REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableTaskMgr /t REG_DWORD /d 0 /f

This works on windows XP as confirmed by my friends at a corporate biggie Thats all!!!

Disguised as a anti-virus, this software calls itself Drive Cleaner 2006 and claims to remove all the viruses in your system. How ironic since this itself is a adware trojan and specifically a virus! Here is how the installation click looks like.

If your computer has files like

C:\Program Files\DriveCleaner 2006 Free\UDC2006.exe

C:\Program Files\Common Files\DriveCleaner 2006 Free\udcsdr.exe

C:\Program Files\Common Files\DriveCleaner 2006 Free\udcpas.exe

C:\Program Files\DriveCleaner 2006 Free\UDC6cw.exe

To remove Drive Cleaner 2006, it is fairly simple process and to remove this virus, just uninstall it from the control panel (There will be a entry called DriveCleaner) and use Hijack This and remove the above named entries for DriveCleane. Hopefully you are clean now!!!
