Early today i was on my cpu and it was doing fine up until the point i tried to access my online game. A message came up stating to me that widows cannot access the specific device, path or file. You may not have the appropriate permissions to access them. So me being simple i rebooted. When i logged back on i couldn't even get on the net, access my security center, change settings in the firewall and a number of other things. Now mind you i did recently upgrade my AVG which i cannot access for some reason. this is frustrating to me as this is the first time it has happened and i'm not all that computer savvy. Can anyone please help me remedy this.
