I have only had my laptop a short while and a friend of mine installed avg free for me.The past week or so there has been a sheild with a cross in it and when i go to security settings and click on malware it is saying my avg reports that my virus protection is off but windows defender is on.I clicked defender and it says i also need another virus protection but when i try to turn avg on it goes straight back to security settings.Also on sunday i couldn't get on the internet or my msn so on monday i had to delete me as the administrator and re-create a new user was this a virus?Can anyone help me sort this out please?
