Just got off the phone with my Dad after trying to diagnose a possible virus on his computer. Every time he starts up Firefox it goes nuts saying there’s a virus incoming and to abort the connection. We set up a Remote Assistance so I could see what was going on and indeed every time he tried to go to his homepage he got a virus warning. That homepage just happens to be Yahoo.com. Here’s the popup he was getting:
Seeing that there was something being appended to the end my first stop was to see what his homepage was configured for in his browser. Sometimes when you install malware on your system it’ll change the default webpage of your browser so it can install even more junk, but pulling up the options screen it was clear that last bit wasn’t part of the URL. That seemed odd so on a lark I tried to pull up Yahoo myself and, sure enough, my Avast went nuts warning me of a virus and showing the same URL. I’m pretty sure both our PCs aren’t unknowingly infected with the same virus so the only logical conclusion is that it must be coming from Yahoo! directly. Either they’re trying to pull something over on their users or their servers have been hacked.
Anyone else experiencing the same thing at the moment? Dad says it was fine earlier today and there’s nothing on any of the tech sites I frequent about it so it must be something that’s happened only recently.
Update: It appears that it’s a false positive with Avast. Manually telling it to update the .dat files cleared up the issue.
