I've made a google search and found something interesting about your problem.
Go to Start > Control Panel > System > Hardware > Device Manager > View > Show Hidden Devices.
Scroll down to “Non-plug and Play Drivers” and click the plus icon to open those drivers.
Then search for “TDSSserv.sys”
Right click on it, and select “Disable”
Note: If you select Uninstall, it will install itself again when you reboot the system, so DON’T select Uninstall.
Restart your pc.
Now use every antivirus you have or any suggested by XpUser4Real.
Don't know if it works, anyway it is worth trying;)
