If you use Interent Explorer, consider this your initiation to the wonderful world of spyware.
You get to do all sorts of fun activities as a result, which includes learning all about spyware -- what it is, what it does, and how to clean it up. Then, if you're smart, you find an alternative to Internet Explorer to use on a regular basis.
My home computer has been acting very weird lately. I have a screensaver loaded for unattended use (which is just a blank screen). At intervals while the computer is on, the screen will come on, the hour glass will be running (although no program is activated). My question is do I currently have a "ghost" in my home or has my computer been inadvertently hacked into?
