Hello,

 

I've recently been fighting some nasty malware that has creeped into my computer that I built a little over a year ago and was working flawlessly up until last month. It started when I noticed some intrusive ads in my Google searches and an extension in my Chrome browser that I didn't recognize nor installed myself. Since then I've done a series of uninstalls and removals on the unwanted programs and extensions using several programs (Mostly Spybot Search & Destroy and Malwarebytes Anti-Malware). At first it looked like I got rid of everything unwanted but I noticed that every so many days the ads and malware kept returning, so I slowly but surely chipped away at finding the source of the problem and I seem to have gotten rid of the bulk of it presently but there's at least one malware that I just can't find and eliminate.

 

It's something that causes my Chrome browser to redirect to an undesired web page when I open a new window in Chrome. It doesn't happen frequently; only once every hour or so. In the meantime, I can open dozens of new windows and tabs without any problems. For the most part, my browsing experience is pleasurable and I simply end the task on the Chrome window that occasionally gets redirected. Other than that, my computer's running fine, so I would simply like help trying to track down this piece of malware that's causing my Chrome to redirect please.

 

Attached are the FRST.txt and Addition.txt files generated from Farbar's Recovery Scan Tool. The two security softwares I'm presently using are Microsoft Security Essentials and Spybot Search & Destroy. I've ran several threat scans in Malwarebytes Anti-Malware and it never detects any threats. Please let me know if there's any other additional system or setup information you guys need and I will be happy to provide it.

Sorry, I forgot to mention. I was looking through the FRST text file and I noticed the section that shows files downloaded or modified out to one month ago. Just wanted to mention that I first discovered strange behavior in my Chrome and the unwanted extensions on March 23rd, just outside the one month window accounting for today after I ran the Farbar tool. Just throwing it out there in case if there's a way to extend the Farbar tool to report further back than 30 days or in case any forum experts need more information. Thanks.

Thanks for the assistance with my problem.

 

I disabled my Microsoft Security Essentials but not my Spybot Search & Destroy (The link does not specifically mention Spybot by name nor is it really an anti-virus software). Not sure if this makes a difference but I felt it best to point it out.

 

I ran the zoek tool and attached the log file to this post. It did prompt me to do a system reboot. After rebooting and viewing the log file, I launched my Chrome browser to return here with my information and I noticed ads starting appearing on my web pages again. I checked my extensions and an unknown extension named "AdPunisher" is now installed. This was not there before I ran the zoek tool and rebooted. It's also making my web navigation and posting here on Malwarebytes difficult.

 

I also attached a screenshot of the extension for reference. I have not re-enabled Microsoft Security Essentials nor ran any additional tools at this time. Awaiting your reply. Thanks.

Re-ran zoek with the script you supplied. It completed and prompted for a reboot. Upon finishing rebooting and checking the log file, I opened Chrome and still see the ads. The AdPunisher extension is still present in my Chrome extensions list. Doesn't seem to have changed anything; still getting web pages redirected, pop ups, and random underlined/hyperlinked text to ads.

 

Does Chrome need to be fully closed when the zoek tool is run? Presently, I'm just clicking the close button in the top, left corner but I have Chrome set to run in the background. In other words, even though I close the browser window, I still see the Chrome icon in my taskbar's notification tray in the bottom, right corner of my monitor. Not sure if leaving Chrome running in the background or fully exiting it will make a difference.

 

Attached most recent zoek log file to this post.

Step 2.

 

 

Chrome installation is altered by malware (fake chrome). Reinstall is needed.

 

Chrome:

CHR dev: Chrome dev build detected! <======= ATTENTION

 

 

 

If you have bookmarks, let's save them by exporting them

Much better results this time around, it seems.

 

Downloaded and ran the AdwCleaner tool. At first it flashed a pop-up saying the version I was running was outdated and asked if I wanted to go to AdwCleaner's web site and download the latest version. I clicked "Cancel" and proceeded to run the version you linked in your post.

 

The scan went by fairly quick and only found a handful of entries in the Folders, Registry, and Chrome tabs. I clicked "Cleaning" and waited for it to clean everything. It then prompted me to do a system reboot. After finishing the reboot, the log file appeared on my screen. It said it was saved in my C:\AdwCleaner folder. When I checked that folder, there were two log files with a date/time created about two minutes apart. I'm guessing one is a log from before I rebooted and the other is a log for after I rebooted since my PC only takes about a minute or two to fully reboot. Either way, I attached both log files to this post since I am unsure of which one you need.

 

After the reboot, I went to uninstall Chrome. I exported my bookmarks as instructed. When I double clicked "Chrome" in the Program List, it asked me to first close all Chrome processes before continuing. I thought this was strange as I had no open Chrome windows or tabs. To my knowledge, Chrome wasn't even running because the notification icon that I usually see in my system tray in the bottom, right corner of my monitor wasn't there. I went ahead and opened Windows Task Manager and found three processes for "chrome.exe*32." When I ended one, the other two ended as well. Returned to the Programs List and double-clicked on "Chrome." This time it allowed me to uninstall. I was presented with only two checkboxes: "Also delete your browsing data" and "Make another browser my default" with a drop-down list saying "Internet Explorer." I'm assuming the "Also delete your browsing data" checkbox is all-encompassing that deletes the profile information, preferences, bookmarks, history, etc. like you said? After this, I proceeded to delete the Google folder under my %LOCALAPPDATA%\ folder.

 

Finally I launched Firefox and proceeded to download Chrome from the link you provided. Downloaded the installer, ran it as administrator, and allowed it to install/update Chrome as needed. When Chrome launched, it prompted me to sign in. I already have a Google account with all my preferences, extensions, apps, and bookmarks synced so I went ahead and logged in. It proceeded to reinstall all my extensions and apps and imported my bookmarks. For the most part, it's back to looking just like it was prior to the uninstall, except for the undesirable AdPunisher extension.

 

So far things are working great. I can open web pages, conduct searches, etc. and don't see any intrusive ads, pop-up windows, or web page redirects. I know we're probably not finished yet but I feel this is significant progress.

    (XP users click run after receipt of Windows Security Warning - Open File).
  • Press the Fix button just once and wait.
  • If for some reason the tool needs a restart, please make sure you let the system restart normally. After that let the tool complete its run.

Downloaded your fixlist.txt and saved it to the desktop. Ran Farbar Recovery Scan Tool as administrator and clicked "Fix." The process completed and put a fixlog.txt on my desktop. It did prompt for a system reboot and the message also said I wouldn't receive any further notifications. I allowed the system to fully reboot. Once finished rebooting, I launched Chrome and returned here to attach the fixlog.txt to my post.

Thanks for all your help. Is there a way you can tell from the log files if my Chrome is truly clean and shouldn't have any problems going forward or will I have to monitor its behavior over the next week or so and see if any problems return or persist? The original problem I had is I would remove the undesired extensions and ads from my Chrome and everything would seem fine for about two to three days; I didn't see any obvious signs of malware, browser hijacking or redirects, or ads. Then after about three or four days, the problem would return, all of a sudden I'd get web page redirects and sometimes ads would start appearing.

Don't worry, Chrome is okay now, all extensions are legitimate.
