Visiting the in-laws, so on a foreign wireless (but that may not matter). I don't want to over-analyze the steps leading up to this problem, so first, the problem.

Upon waking Windows 7 (Dell) laptop up from sleep mode, opened Firefox 5.0beta and rather than www.google.com (my homepage) I saw an error 404 nginx error. Only saw that once, but now any attempt to browse to google's front page with either Firefox or Chrome yields a "Welcome to nginx!" white page. Sub-pages of google are no problem. IE has no problem (very suspicious). I note that my default search engine in my FFX toolbar has also switched away from Google to Yahoo.

I always have Symantec AV 10 running, but this startled me enough to run a full scan. Found some things lurking in my Thunderbird trash - those were deleted. Problem still there.

Installed Malwarebytes and it found a couple of things. Those were deleted. Problem still there.

Installed IOBit 360. *It* found a couple of more things, those were deleted. Problem still there.

Unfortunately, found ComboFix at Download.com before seeing instructions here and so I already downloaded and ran it. It thinks it found one thing and deleted it. But at that point I connected here and now am going through the instructions posted in the pinned forum. But for now, is this an obvious thing? I suspect from what I've seen online that it's a rootkit thing (but am not sure what that is, exactly) nor how to fix it.

Don't want to step on toes by doing things out of order. What's next to get some help?

thx.

A few weeks ago, when I attached to a (trusted) wireless connection at the in-laws house I started getting a blank "welcome to nginx" screen only when I tried to go to www.google.com via Firefox or Chrome (IE worked). Higher pages of google worked, just the front page was bad. Ran Norton (which I always have running) and it found nothing. Malwarebytes found a couple of suspected "trojans" which I deleted, I scanned using iobytes 360. Without having found this site yet :( I found reference to GMER and had run that as a scan. Then, suddenly, a few days later, it just stopped. Now, I've connected with a "foreign" wifi again (testing a demo phone from Verizon and using the hotspot feature) and IT'S BACK. Can someone help me with the ghost lingering in my machine?

<sigh> I'm not sure I can find the very first Malwarebytes scan... I'm looking now. I was a bit (cough) freaked out, so I ran it more than once... I found a log from the first evening (this started in the morning) showing nothing, so I'm worried the original was overwritten. I do know it originally claimed to have found three trojans, but I'm not sure they were "real". I will attach the IOBit 360 log, which found an HP printer driver that it thought was a trojan.

As I backtrack (it has now been a couple of weeks and since I didn't get help on my first post here I unfortunately tried a bunch of stuff on my own) I see I ran combofix and it produced this quarantined file log:

Does this help? I'll wait to hear what is suggested to do next. Thanks!

Since you have ran Combofix, Please follow the instructions in ==>This Guide<==.

Once the proper logs are created, then make a NEW TOPIC and post it ==>HERE<== Please include the link to this topic in your new topic and a description of your computer issues and what you have done to resolve them.

If you can produce at least some of the logs, then please create the new topic and explain what happens when you try to create the log(s) that you couldn't get. If you cannot produce any of the logs, then still post the topic and explain that you followed the Prep. Guide, were unable to create the logs, and describe what happens when you try to create the logs.

Once you have created the new topic, please reply back here with a link to the new topic.

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/topic405452.html you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a MRT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the MRT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the MRT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the MRT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

To avoid confusion, I am closing this topic. Good luck with your log.
