Seven years is probably pretty good by todays standards. I, however, run computers for ever. I haven't had my current laptop for a year yet. I replaced my 12 year old laptop. My old lappie still works but it is 32 bit, 512k memory, can't run the newer operating systems and has a failed cooling fan. I need to replace that fan and then see if I can continue to use it with linux or something.
Well done with posting in the Windows Forum. You're in good hands with Paws.
Good luck over there. I'm going to close this thread as there isn't anything more to do as far as malware is concerned. The information will still be available, you just won't be able to post in it anymore.
