I doubt its a virus problem, possibly hardware, or like the above suggested internet, obviously if youve tried on several pcs its not hardward, but a system restore point may help on either machine, or you may have got a virus from elsewhere, if youve not got protection. if you can log in to other sl things its not your account. Try logging in at Smith or a sim you know that is empty, it may be the place youre trying to enter that is causing the problems.
