Hi,
I am trying to uninstall BitDefender Internet Security 2010 from my Windows 7 OS, but during the uninstallation an error arouses:
Service VSSERV "Bitdefender Virus Shield" could not be deleted.
I am the admin, with the only account on the PC. I saw that the BitDefender uninstall tool does not support 2010.
I saw that the owner of the vsserv.exe file was the "SYSTEM", and couldn't get it changed.
Any suggestions? 
ps. I have the same problem as this user: http://forum.bitdefender.com/index.php?showtopic=7145
