Hi people I have two problems that may be related and couldbe viral. Firstly - on shut down my pc goes through all the usual steps but instead of automatically switching off a dash appears at the top of the screen and I have no option but shutting the pc down by switching it off. on restart it always wants to do a scan disk. Fearing a virus I opened norton and to my surprise after 10-20 seconds the norton program shuts down and disappears. The same happens with mcfee ?????????? Now I'm stumped all other programs operate without problem but I know there is something somewhere upset or infected. Please help.
