No clue, but she's got a history of unsafe surfing habits, (56 now) I was surprised that her moms computer that she brought over last night wasn't bad. Issue was shutting down and had a "Antispyware Doctor" issue, That was a persistent rogue spyware app, but before I could remove it I needed to fix the shutdown issue.
I opened it up (Compaq from the late 90's BTW, yea, moms a cheap ass) and found 12+ years of dusty cat hair clogging everything. All the power supply vents were clogged, the back vent, couldn't hardly recognize the vid card or memory and the CPU fan was just a brown blob. Pulled the CPU fan off and the heatsink was absolutely packed. All together I bet I vacuumed,blew, brushed and tweezed about a softballs worth of crap out of it.
