Ok so after all the updating i did and cleaning of my computer, i went to school yesterday with malewarebytes, comodo firewall and avira antivirus on my computer, so i turn my computer on and it trys to connect the the school network which supposedly it does successfully, but then i go to open up google chrome and i can only access some websites but then it stops and i cants get on any websites and then my avira stops having the guard up and then it wont let me update it. So at first not knowing what it could be, i try a system restore to the night before but it doesnt help any. so now after comming home and uninstalling both comodo and avira i try to reinstall avira which now it says the guard is active but it still wont let me update. Any ideas on what i can do? Pleaseeeee help
