First, a few specs on my operating system: I live alone and use one single computer. It is an E-Machine T4010
, equipped with Windows XP
. My ISP is Verizon
and my modem is a Westell VersaLink model 327W
. I am using Avast Anti-Virus Home Edition
, as well as Spybot Search & Destroy
Something very disturbing has started happening recently. I'll be on-line, and apparently somebody else starts accessing my computer from a remote location. Suddenly I am unable to type anything into the URL window (it just drifts to the side), and the computer is for the most part, under the control of someone else.
Whenever I notice this happening, I immediately shut off the modem. When I try to shut down the computer, a screen pops up that reads something to the effect of: "There are two parties currently logged into Windows. Do both of you wish to log off?" Needless to say, this is quite unsettling. Somebody could very well be using my computer to conduct illegal activity. No viruses turn up after a thorough avast scan.
My Windows firewall is always on, and last evening at around midnight, it happened even while my security and privacy settings were both on HIGH. It almost always happens during the wee hours of the morning, while I'm listening to an internet radio program. If I happen to be looking at the screen, I can instantly tell when it starts, because the screen saver never pops up.
Any help you can give me in preventing this from continuing would be much appreciated. I'm not even sure if it's something to do with Windows or the Verizon people. Is there some button I can push on this thing that will specifically forbid access from any location other than this one?
