I almost got caught by one of those a couple days ago, on my wifes computer. I clicked "NO" on the question that was presented and got put into an endless loop....finally had to reboot to get out of it. In the future, I'll just click on the X to close the window instead.

I use AdSubtract and SpySubtract on my main development computer, so, normally I don't see the pop-ups.

>She has XP and I believe SP 2 has been already installed on her pc. And I doubt very much that MSFT updates this way: a pop up window with offer to update without a company name or what or cancel button. I have seen these pop ups and will always answer No. But my daughter was naive (I should have warned her about these things).
>And they have a very fast network on campus, so I think it is a trojan or some other of those types.

>>If she has XP, it could be the XP 2 update. It takes quite a while to install but shouldn't be all night. Her connection speed could be a factor??

>>>My daughter called me this morning (from college) and said that last night when she was online a window popped up and asked if she wanted to install an update. She said Yes. The "update" has been "installing" all night. I told her to shut off the notebook. She did but when she starts the notebook again, after a little while, she gets the window that "update" is being installed, still.

>>>I have two questions:
>>>1. What possible are they doing to her pc while "installing" update?
>>>2. What link or program I should send to her to get rid of this "program" that is probably installed on her pc?

>>>Thank you for any suggestions.
