6 computers in our home all acquired the search redirect problem on Saturday. 3 XP machines, one Vista, two Windows 7 64-bit (lots of kids)
I have tried virtually everything on each machine. That includes on most running RKill and Combo Fix, per some advice on other posts here. If that was a no-no, I apologize, but I was desperate. I encountered no problems doing so, and in some case RKill did appear to find a few things. I cannot tell if ComboFix did anything or not.
I have tried virtually every AV that exists, including Malwarebytes (more in a moment), SuperAntivirus, Prevx, and Spybot. I did try the Kalwaski TDSS thing (think that isn't quite right but hopefully clear) and it found nothing.
These efforts somehow do seemed to have tamed the beast but I do not believe eliminated it (still unsure on a couple of computers).
The virus has several effects:
1. When clicking on a link on a search page in any browser (IE, Firefox, Chrome) it will take you to another page - those pages are all over the map in terms of what they are. Many are strange.
2. Now, esp. on the W7 machines, it seems to open the right link, but open another tab and page as well. Just recently got a StopZilla page when clicking on some search regarding this problem.
3. It blocks certain sites. Initially, we could not even get to Malwarebytes.org, but now largely can.
However, we could not download the latest updates, automatically or in the relatively new manual mode (generally, a "page not found error" was encountered). That, however, was through a Roadrunner modem/router. Just now, I got on-line through my Verizon wireless card, and the auto update worked just fine. Unfortunately, the scan with the new definitions is not finding anything, as I was very much hoping.
There doesn't seem to by any even real knowledge as to how serious this is out there.
So, 6 computers infected seemingly at once - what does that say?
Can get to M-bytes to auto update with USB card but not through regular wireless or cabled connection - ditto
Is there any other approach to removing the thing? Though based on recent threads, I am not optimistic, at least right now. Most seem to still be up in the air.
I did talk to Roadrunner level 2 support, but they would not look into the router. They did reboot the modem, and I rebooted the router. But I am wondering if the router has been compromised, given my experience (same computer doesn't update with RR, but does with USB broadband card - is it bloked at the router?)?
I realize this is two problems, maybe, but seem integrally intertwined.
Would love to be test case to find a way to address this. I am pretty good with this stuff, but don't know what else to do at this point.
Will note that the hosts file on one XP machine looked to have problems (some extra lines) and was restored. Just restored hosts file on W7 machines without really looking at it. Some XP machines seem to still have normal hosts file.
