My sister's laptop has a problem where when she tries to open a Hotmail attachment it says it contains a virus. She doesn't have any anti-virus software and since we both are Comcast customers I decided to get the Norton package they provide. When I tried to download it I also received a message saying it contains a virus and was deleted! It had the red shield with a white X so I started looking around. I checked her Windows Firewall and when I try to do anything with it (turn off or on, change settings), a window pops up saying "Windows firewall can't change some of your settings. Error code ox8007042. I did some Google searches on this but see all kinds of info, but not sure which one I want to follow. Looking if there is a fairly straight forward & current procedure to deal with this.
The specifics are:
Toshiba Satellite L755
Windows 7 Home Premium, Service Pack 1
I.E. 10.0.9200.16660CO
Any guidance appreciated, thanks.
