I used Bitdefender for a year, it worked well until a keylogger was detected, it couldn't remove the keylogger without the password. Then I restored my PC which was really complicated to me, so I wanted to try some other softwares to protect my computer, here are some softwares I searched on google. Kaspersky, Webroot, Norton Security. Which one is better?What about its price? Any information will be thanked.
