Is there some built-in MS anti-virus scanner, or something that gets automatically downloaded on certain occasions? I'm sorry if part of this question is vague. My ex-gf was annoyed at her computer and impatient with me and I got a discription in dribs and drabs, and incompletely. She seems to have a virus. When she started winXPSP3, she got a green shield and a message that she may have a virus, and it gave 4 or 5 suggestions of what to do. I don't know what the other suggestions were. She chose to run some anti-virus that it suggested, and hten changed her mind and called me. The only anti-virus she has is AVG, and I suggested she do a full scan with that, but it wouldn't start. When she clicks on AVG icon in systray it says: "application can not be executed if avgui.exe is infected" Restarting gave the same first message. This time she told me about the green shield and that the message was in an IE box. Should she have let that anti-virus run to completion? At first I thought it was one of the web scan/scams, but maybe it's good??? Last night I dl'd the latest copy of Bit Defender Rescue Disk, and it is far different from last December's version. I'm going to give her the CD at work today, but it would be simpler if the suggested scan was a good thing to run. Separate question: Why don't Dell computers have a reset button? Thanks.
