Thank you for your reply, even though it wasn't what I wanted to hear
I tried to follow the directions you provided and ran into a couple of snags. First off, the spyware programs you recommended scanned my computer, but require a paid subscription to remove what they find. I have a program that "supposedly" looks for the same things but comes up empty after scanning. This is my parent's computer and I hesitate to install anything until they ok it (I am house sitting while they play snow birds).
Second, I was in the process of scanning with Housecall when the window spontaneously shutdown. Hmm . . .
I should mention my first attempt at scanning with Housecall (just minutes before) froze up the computer and I had to reboot.
I have had bad experiences with Panda freezing up computers in the past.
Never tried Bit Defender.
I haven't tried the McAfee AVERT Stinger yet, and do not have time to do so as I must go to work soon and won't be back until late Sunday night.
Shall I go ahead and DL HijackThis as my next course of action? Any other suggestions?
