Hello, I started getting popups telling me i need to install winifighter a few months ago, and have been trying to remove the cause (unsuccessfully). The malware seemed pretty harmless (redirecting google searches done in IE [which I hardly ever use] and fake alert popups telling me to install winifighter [in ALL browsers]). I followed directions on a thread here created by someone with similar symptoms and it appeared to be gone... but RootRepeal found C:\WINDOWS\system32\drivers\ESQULntyxtuwuybwwakiwqtoqxwbapqmbgcij.sys in hidden services which was part of the rootkit and I thought was gone. Then the popup reappeared while I was using firefox (screencap attached) and I've kind-of given up hope correcting this myself... help, please?
I'll post screenshots, logs, etc. when asked

Symptoms: numerous anti-malware programs fail to run, avg crashes, fake windows security alerts in all browsers, a large number of junk files in system32 named things like 5tealdatadkhjdfbkh.bin (bin, cpl, and exe files)

EDIT:spelling, added more symptoms and screencap

the "error" in firefox

Hello and welcome to Bleeping Computer.

Please subscribe to your topic so that you will be notified as soon as I post a reply, instead of you having to check the topic all of the time. This will allow you to get an email notification when I reply.

Lets take a look with Malwarebytes

Please download Malwarebytes' Anti-Malware from here:
Malwarebytes
Please rename the file BEFORE downloading to zztoy.exe instead of mbam-setup.exe

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.

Double Click zztoy.exe to install the application.
* Make sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select "Perform Full Scan", then click Scan.
* The scan may take some time to finish,so please be patient.
* When the scan is complete, click OK, then Show Results to view the results.
* Make sure that everything is checked, and click Remove Selected.
* When disinfection is completed, a log will open in Notepad and you may be prompted to Restart.(See Extra Note)
* The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
* Copy&Paste the entire MBAM report (even if it does not find anything) in your next reply

Extra Note:
If MBAM encounters a file that is difficult to remove,you will be presented with 1 of 2 prompts,click OK to either and let MBAM proceed with the disinfection process, if asked to restart the computer, please do so immediately.


If Malwarebytes won't install or run

Some types of malware will disable MBAM and other security tools. If MBAM will not install, try renaming it. Right-click on the mbam-setup.exe file and change the .exe extension to .bat, .com, .pif, or .scr and then double-click on it to run.

If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files, right-click on mbam.exe and change the .exe as noted above. Then double-click on it to run.

So far everything seems fine, though I am still a little concerned about a .sys file that RootRepeal finds when I run a hidden services scan. The RootRepeal scan shows
Service Name: ESQULserv.sys | Image Path: C:\Windows\system32\drivers\ESQULntyxtuwuybwwakiwqtoqxwbapqmbgcij.sys

RootRepeal give me a "Could not find the file on disk!" error when I try wiping it, and I cannot find either file. Should I be concerned? And how can I get rid of the service?
