Not sure if posting in the right place, but this is more of a question than a request for malware/virus removal...

I have a Windows Vista, with a recently installed SP2 (I think), and have McAfee VirusScan 8.5.0i, Malwarebytes 1.41, and Windows Firewall (all required to access school network).

A couple days ago, McAfee detected a file (yifopuse.dll) that it couldn't delete. It had disabled Task Manager and didn't allow me to unregister the file from the command line, so I started up the computer in Safe Mode. It wouldn't delete there either, so I downloaded Autoruns.exe and deleted all the non-verified and non-recommended programs (checking with Google and BleepingComputer.com). I was finally able to get rid of the yifopuse.dll file, along with some other randomly named files that had recently been downloaded in the same folder, which I assumed were also bad. Booted up Windows normally, ran scans from McAfee and Malwarebytes, which both detected and deleted some other trojans. I also ran checks in Safe Mode today, both turned up empty. However, since then, Malwarebytes is still blocking access to random IPs, McAfee has disabled itself at least once out of the blue, and I'm having some problems with Firefox and Explorer.exe freezing up. Maybe something got deleted that shouldn't have, or just another one of Vista's many problems?

At this point, I'm wondering if I got all of the files and can safely use my computer again. Thanks!

Also, I think all of this came from an infected external hard drive I used in China. Unfortunately, I still need the hd (it has all of my system backups), so is there any way I can clean it too?

Hi SAKitty,

From what you tell me, I think you still might have some things going on at your computer.

ROOTREPEAL
-------------
We need to check for rootkits with RootRepeal
  • Download RootRepeal from the following location and save it to your desktop.
  • Extract RootRepeal.exe from the archive.
  • Open Posted Image on your desktop.
  • Click the Posted Image tab.
  • Click the Posted Image button.
  • Check all seven boxes: Posted Image
  • Push Ok
  • Check the box for your main system drive (Usually C:), and press Ok.
  • Allow RootRepeal to run a scan of your system. This may take some time.
  • Once the scan completes, push the Posted Image button. Save the log to your desktop, using a distinctive name, such as RootRepeal.txt. Include this report in your next reply, please.

regards, Elise

Quick question, are you not supposed to run any other programs (like Firefox and Paint) while RootRepeal is scanning the system? I tried to browse the internet and open up My Computer, but everything froze rather badly and I had to force shut down my computer (holding down the power button). This may or may not be the RootRepeal's problem, since I also had trouble accessing the folder that it got downloaded to (it was not responding) and was given a "Logon process has failed to create the security options dialog; Failure - Security Options" error when I did ctrl + alt + delete the first time...

I will try running it again and see what happens.

Hi,

The scan never completed. I ran it overnight and during the day, for about a total of 18 hours, but it didn't complete scanning -- it froze my computer so badly that the screen was on and black for about half an hour before finally pressed & held the power button.

It was working okay last night (still had to force quit the computer twice). I had it running in Safe Mode for a period of time as well, but it passed a folder without recording anything when it recorded something in the folder when it was scanning in regular mode. Between last night and this afternoon - It likes to make every program I click go into "Not Responding" mode for a couple of minutes, before everything resolves all of a sudden. The RootRepeal window does not respond for a couple minutes when I click on it to check the progress, and when everything else also freezes up in turn, the ctrl+alt+del and ctrl+alt+esc keys don't respond, or if it does, it gives a "Logon process has failed to create the security options dialog - Failure - Security Options" dialog box. However, this time nothing responded for about an hour and the screen was on but turned black; it didn't respond to *anything* so I forced my computer to shut down.

Is there anything else I can do to see what's going on? I would run the Rootkit program again, but it really takes up too much time and I do need to use this computer for schoolwork and don't have convenient access to other computers. Before RootRepeal died, there were about 7 files listed on the windows pane, any way to retrieve that? Also, my computer is either freezing, turning the screen black for a while, not responding, or taking forever to even normal commands, such as ctrl+alt+del, opening My Computer, clicking the Start Menu, and running Explorer.exe. Since RootRepeal did not terminate properly, perhaps it's still running in the background?

Edit: Ctrl+alt+del still gives the same error, Windows Explorer is not responding (supposed to open to My Computer), and explorer.exe is also unresponsive.

Lets try another rootkit scanner. The things you describe are not normal for a RootRepeal run. It is true that such a scan can take up to a couple of hours, depending on your system and the amount of data, but this is not quite normal.

GMER
-------
Please download GMER from one of the following locations and save it to your desktop:
  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.

    Posted Image
  • GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and re-enable all active protection when done.
-- If you encounter any problems, try running GMER in Safe Mode.

regards, Elise

In Safe Mode, I unchecked everything in the Preferences and only checked the "Close Browsers before Scanning", "Scan for Tracking Cookies", and "Terminate Memory Threats before Quarantining" boxes (I guess the Preferences didn't save?). After the scan completed, I clicked Next, then Ok to remove files, then a box asked for a reboot to complete the removal, so I clicked okay on that -- I didn't get the "Quarantine & Removal is Complete" message, I just did the reboot, if that's okay.

Here's the log:

It's running pretty well now, just a bit slow opening/loading/switching windows. Also, should I uninstall SUPERAntiSpywareFree, since I have McAfee? And should I contact my bank, since I did check my online banking account while I had the bug on this computer? :/

Thanks so much for your help! :thumbsup:

Edit: Chrome just froze out of the blue while I was listening to Youtube and the Security Center reported that McAfee was turned off (when there wasn't a sign saying McAfee was turned off on the icon tray). Maybe a bad Youtube video?

You can leave Superantispyware just fine along McAfee. McAfee is an antivirus and SAS is an antispyware application. Just do not enable the realtime protection in SAS, since it consumes quite a few resources and may slow down your computer...

As for the problem you encountered. There could be indeed bad YouTube video's. Restart your computer and check if McAfee is running after that.

regards, Elise

Thanks so much! Everything's working great now! :thumbsup:

One last question - I think the infection started from my external hard drive when I plugged it into an infected computer; is there any way I can check/remove the bad files on my external without re-infecting my laptop? I think it may have spread to some other devices too.

Concerning your back up drive, if it is only backup, and your current drive is fine, I really would recommend reformatting and re-backing up all your data. Otherwise, when you are forced to use your backed up data, you risk infecting your system.

Concerning all external devices, its always a good idea to use Flash Disinfector.

Please download Flash_Disinfector.exe by sUBs and save it to your desktop.
  • Double-click Flash_Disinfector.exe to run it and follow any prompts that may appear.
  • The utility may ask you to insert your flash drive and/or other removable drives. Please do so and allow the utility to clean up those drives as well.
  • Hold down the Shift key when inserting the drive until Windows detects it to keep autorun.inf from executing if it is present.
  • Wait until it has finished scanning and then exit the program.
  • Reboot your computer when done.
Note: As part of its routine, Flash_Disinfector will create a hidden folder named autorun.inf in each partition and every USB drive that was plugged in when you ran it. Do not delete this folder...it will help protect your drives from future infection by keeping the autorun file from being installed on the root drive and running other malicious files.


You might want to consider the following information :trumpet:

Please read these advices, in order to prevent reinfecting your PC:
  • Install and update the following programs regularly:
    • an outbound firewall
      A comprehensive tutorial and a list of possible firewalls can be found here.
    • an AntiVirus Software
      It is imperative that you update your AntiVirus Software on regular basis.If you do not update your AntiVirus Software then it will not be able to catch the latest threats.
    • an Anti-Spyware program
      Malware Byte's Anti Malware is an excellent Anti-Spyware scanner. It's scan times are usually under ten minutes, and has excellent detection and removal rates.
      SUPERAntiSpyware is another good scanner with high detection and removal rates.
      Both programs are free for non commercial home use but provide a resident and do not nag if you purchase the paid versions.
    • Spyware Blaster
      A tutorial for Spywareblaster can be found here. If you wish, the commercial version provides automatic updating.
    • MVPs hosts file
      A tutorial for MVPs hosts file can be found here. If you would like automatic updates you might want to take a look at HostMan host file manager. For more information on thehosts file, and what it can do for you,please consult the Tutorial on the Hosts file
  • Keep Windows (and your other Microsoft software) up to date!
    I cannot stress how important this is enough. Often holes are found in Internet Explorer or Windows itself that require patching. Sometimes these holes will allow an attacker unrestricted access to your computer.
    Therefore, please, visit the Microsoft Update Website and follow the on screen instructions to setup Microsoft Update. Also follow the instructions to update your system. Please REBOOT and repeat this process until there are no more updates to install!!
  • Keep your other software up to date as well
    Software does not need to be made by Microsoft to be insecure. You can use the Secunia Online Software occasionally to help you check for out of date software on yourmachine.
  • Stay up to date!
    The MOST IMPORTANT part of any security setup is keeping the software up to date. Malware writers release new variants every single day. If your software updates don't keep up, then the malware will always be one step ahead. Not a good thing :flowers:.
Some more links you might find of interest:

Is there another place where I can get Flash Disinfector? I downloaded it, but McAfee immediately detected/deleted the file/Generic.dx, classified as a Trojan, and I can't access the link anymore.

You could try to whitelist it in McAfee. As far as I know it has only one download mirror and thats the one I gave you.

Just for your assurance, this tool is absolutely safe. McAfee recognizes it as bad because it changes the autorun settings and 'intrudes' your usb device.
