Alright Well just recently i had to get rid of av security suit one of the ones that hold your pc hostage until you buy there product. I have no idea were it came from ok i have some what of an idea. Please tell me if im wrong in doing this. So i decided to add a website blocker to my computer because my gf my step sis my mom and step dad use this computer. I warned and warned them to be careful but know they click things and what ever. I tired of having someone or me to remove theme its so tiring.
There's a wonderful thing called Spybot Search & Destroy. Can be found here. It automatically add like 1000s of bad sites to your hosts file and you can scan for malware and stuff. Hope I helped. 🙂
