I used trial version cannot unistall

I used trial version cannot uninstall since i forgot settings password. I cant break it because its a 7 or 8 lettered pass with all characters - Uppercase lower case ad numeric how to recover such password. tried regedit tried searching in application data all files related to stored settings password. now i cant uninstall as i forgotten my settings and trial period has expired and want to install other A/v .since i have virus and don't want to format my pc tell me what to do

 

I cannot access the settings - I'm being asked for a password. What should I do? Basically it says you need to contact costumer care to give you a unlock code and utility.

 

thank you

 

i dont have internet at home . i just use AV to protect me from usb virus
