Hey everyone, I have an issue with my computer that I've been struggling to fix for a while now. I have a Dell Vostro 1500 laptop running Windows XP Professional SP3. I use Firefox 4 to browse the internet. I have two problems which I think are closely related. First, sometimes when I search something on Google, and then click on one of the search results, a new tab opens up in my current browser window and takes me to some random website, usually advertising local listings. I often see the phrase "google-analytics" in the URL of the site to which I get redirected. Second, when I am browsing certain sites (for example, cracked.com, a perfectly legitimate website), I frequently get popups in the form of new browser windows opening up on top of my current one. This usually happens when I click on a link, and sometimes the first time I click my mouse anywhere on a newly opened page. Both of these things are abnormal, since I have gone long periods in the past without having to deal with them.
The problem didn't appear until I moved back in with my parents after my college graduation a few weeks ago, and started using their wireless network. Apparently, the other computers on my family's network have been having this problem since before I came back, and my dad thinks it might be an infection of the network itself. I don't know if his theory is correct, or if it even makes sense.
I normally run the free trial version of either AVG or avast! on my laptop. When the 30 day trial of one program ends, I uninstall it and install the trial version of the other one. Alternating back and forth between the two has worked pretty well for my internet security for about a year and a half now. I'm currently running AVG, and its scans aren't finding anything. I also have the free version of Malwarebytes as a passive anti-malware program. Malwarebytes doesn't yield anything either. Finally, I have Kaspersky's TDSS Killer program, which helped me solve a similar problem at one point in the past. It also doesn't find anything, although I have the most recent update.
That's my situation. If anybody needs any more clarification, please let me know and I'll provide any information that I can. Thanks in advance for any insight you guys can give me into this problem. Also, as a bonus, I was wondering if anyone has any favorites as far as internet security programs. Let me know what you think, and thanks again.
