All my sphincters are in lockdown. Normally my mother is extremely suspicious of strangers calling, but for some reason, this slipped by her. She apparently spent quite a bit of time the other day on the phone with someone "trying to help her fix technical problems with her Microsoft" system. She obviously gave them access to her system, since she said that they were manipulating her cursor and accessing various places on her computer. She's away for a few days, so I dropped by to check out the damage. As far as I can tell, there are no obvious lasting effects. No software installed that I can see. I ran a virus check, turned on the Windows Firewall, and searched the drive to what has been installed during the time in-question. Still nothing. I am highly dubious that they would put their grubby paws all over her system, yet not install anything. Maybe there's something on there that's invisible, or simply looks innocuous to my eye. Does anyone have any suggestions for a deeper search?
