Seems no one has had this problem for a while. I installed Avast! on a friends' system awhile ago and she called me up today to say that she got this message when she went to the yahoo main page. I assured her it was a mistake but to make sure, I told her to scan her whole computer. She did and came up with no viri or malware. I advised her to try to go to other websites. She successfully went to 5 or 6. She even went to other Yahoo! websites. It was just when she typed in "
http://www.yahoo.com/" that she got the warning and the option to "Abort Connection". Just because I was curious, I did it myself. I too got the message that a "virus" was found when I went to the site. It's funny that the URL showing is "
http://www.yahoo.com/" but the Avast Warning indicates "
http://www.yahoo.com/\unp34785754". Fooling around, I find the numbers at the end change every time I connect to this page. I believe I have the latest VPS version (080622-0, 06/22/2008) even though in previous posts on this thread indicate it was a False-Positive and would be fixed in the next VPS version - and that was months ago.
The reason this is important is because this friend knows just about enough about computers to ask the most stupid questions (a la, "What kind of bait do I use to get rid of that mouse pointer?") You know, you've met computer users like that. It took 20 minutes to get her off the phone after I showed her how to do a scan. She has a 250GB drive and wanted to stay on the phone until it was done. This is even though I told her what to expect if she FOUND a virus/malware and told her to call me back if that happened. Anyway, I'm stuck with her for another 11 months (contractual phone/home technical AND hardware support), but she's driving my nuts.
