I have Symantec AntiVirus 10.2.1.1000 installed on Windows 7 x64.
I want to uninstall the antivirus.
When I try to do it a window appears: Enter password for uninstall.
But I forgot the password.

Is it any way to remove the antivirus correctly?

Try the password

open task manager

look for Msiexec.exe under loggged in user name. 

Kill only that msiexec. after that the uninstall should run..
