I've been experiencing a browser hijack on my main desktop computer as well as my laptop computer and on my kids' computer. The hijack occurs with both Firefox 3.6.6 and Internet Explorer 8, but it's much worse with IE (at least with Firefox, after one or two redirects, I can use the browser again whereas with IE, it's a never ending string of redirects).
Here are some of the sites that I'm redirected to when searching with Yahoo on IE:
I've had all three computers looked at and cleaned, but as soon as I get them home and put them on my network, the hijacks start again. At one point, I did a clean reformat and installation of the operating system on my laptop, only to have my very first search on Yahoo be redirected.
Malwarebytes is used regularly on all three computers, and McAfee is installed on all three as well. Spybot S&D is on two of them, and none of those software suites are detecting anything (in fact, I just installed Spybot today and ran it - according to the instructions in the tutorials on this very site - and got a clean bill of health. My searches are still redirected.)
I have Verizon FiOS as my internet service provider; one computer is connected by network cable, two others are wireless. All computers are running Windows XP SP3. The most recent time I had my laptop cleaned, I tried it on other people's networks first and had no problem, but as soon as I got it home, the redirects started. As a result, I still haven't hooked the main desktop back up since I got it back from being serviced since I don't want it to get reinfected - or whatever is happening to them.
I'm starting to think that the network itself is infected, but I wouldn't know how to go about proving that, much less remedying it. Anyone have any ideas?
