Hi, and thanks in advance for any help. I definitely have a little spyware on this computer. It's Windows XP. It only manifests itself by either turning my master wave volume all the way down or random audio ads that come from nowhere. Also Internet Explorer windows open infrequently with ads out of nowhere.

I've run Malwarebytes Anti-Malware, rkill, SuperAntiSpyware, and Spybot Search and Destroy and they pick up nothing. Hitman is the only thing to pick up two problems (labeled "smss.exe" and "services.exe") in the C:\System Volume Information\Microsoft folder. I've gained access to it by changing view and security settings and tried to manually delete the two files (which are labeled as "File Loaders" and "Black Internet"). It always says 'access is denied,' even when using Unlocker. Any attempt to delete upon reboot using Unlocker hasn't worked.

Hitman finds them, says it's removing them, and then says they will be removed upon reboot. I reboot and either one or both are still there. Any ideas?

Incidentally, when it starts up after rebooting, Spybot picks up that 'an important registry entry has been changed' and asks if I want to allow the change to the entry "BootExecute. Old data: autocheck autochk *\bootdelete. New data: autocheck autochk *\" I've tried both allowing it and denying it, and the trojans are still there.

Thanks for any help!

Hello, the C:\System Volume Information\Microsoft folder is the System Restore Point folder.


Now you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been backed up, renamed and saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Vista and Windows 7 users can refer to these links: Create a New Restore Point in Vista or Windows 7 and Disk Cleanup in Vista.

Thanks, I'll try this. I should say that I tried a System Restore yesterday, restoring to the day before I started having problems. It hasn't made a difference with my problem. Should I still try the above method? Thanks.

That is why we want to do this process.. Restoring back to an infected state wil obviously reinfect you. Restoring does not remove other malware. Only removing them from the system Volume (Restore point ) will and then only those it has stored.

Wouldn't creating a new Restore Point now, when my computer has this malware on it, and deleting the old ones, just be saving an infected point? You say "Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state." I haven't cleaned my system - that's the whole problem. The malware can't be deleted, so saving a Restore Point now would be preserving it, no?

I think you have cleaned the system.. all scans came back clear you stated. So the only thing is the sys vol where the tools cannot access.
Are you still having malware symptoms??.
then Rerun MBAM (MalwareBytes) like this:

Open MBAM in normal mode and click Update tab, select Check for Updates,when done
click Scanner tab,select Quick scan and scan (normal mode).
After scan click Remove Selected, Post new scan log and Reboot into normal mode.

I tried to clean the system with all those tools and they all came back clean (except for Hitman which identified the two files I said). I have had malware symptoms continuously, despite the clean scans (again, except for Hitman). The random wave volume control, the random audio ads, Internet Explorer asking to be my default browswer when I hadn't opened it (there are often 2-5 iexplore.exe listed in my Processes tab of Task Manager even if I don't have IE open). I'm guessing IE is opening randomly and invisibly and playing the ads.

Now when I run MBAM it found 5 things. I'm rebooting after posting this. The log is below:

Just rebooted, same ads, same note about Internet Explorer starting (even though I haven't opened it). Hitman still picks up the smss.exe and services.exe in my system volume information/microsoft folder and says it will delete on reboot. The first 5 times I've rebooted, the problem remained after so I don't know why this time would be any different.

This time, after Hitman said it would "delete on rebooting," I got a blue screen as Windows was starting up, saying "Hitman" and listing the two files. THEN I got a blue screen of death, saying that there was a 'fatal system error' and the windows logon process was terminated with a status of 0x00000402 and that it had been shut down.

Had to turn off the computer, start up again. Big surprise, upon startup Hitman finds the same two trojan files, wave volume goes down magically, and IE no doubt open somewhere behind everything sending out ads over the audio. I got nothing.

Ok, let's look for a rootkit... you will need to shut off all these tools we have going first.

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 be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.
-- If you encounter any problems, try running GMER in safe mode.
-- If GMER crashes or keeps resulting in a BSODs, uncheck Devices on the right side before scanning

I don't know why MBAM isn't picking up the two trojans. I even highlighted the "Microsoft" folder in the System Volume Information and said "Scan with MBAM." Came back clean. IE pop-ups and audio ads continue.

I was running a GMER scan as instructed. After it had been going for about ten minutes (listing things in the window) my computer shut off and restarted. Should I be running it again?

@boopme

Not sure if you saw my post, but I have the "exact" issue that is being addressed here. The topic is [LINK] I also was able to get rid of the SMSS and Services.exe using the XP Recovery Console, but they all came back. More details in that post. I figure I would just watch and see how/when you guys get it worked out. I am going to try the GMER this morning. I will update the other post I referenced.

Also, seems to be the exact issue also on Major Geeks, see thread "Help with Black Internt trojan"
