Hello,

I know youíre going to yell at me Ė but I ran the Combofix. I have been dealing with some kind of virus or spyware issue for at least a month (probably longer) and its just making me nuts. I have run several different types of malware identifiers and still no luck (SpyBot, MalwareBytes, Exterminator Ė and others I canít remember). Iíve also repaired the OS.

Symptoms are that about 3 or 4 months ago all but 1 of the USBs stopped responding. I can hook up one USB 4 port hub and that works OK. But the others that are in the computer donít work. When I look at the registry it says Ė BADDEVICE.Dev Then, over the past 3 Ė 4 weeks the computer started to hang and now it hangs way too long. Many times it ďtimes outĒ. I kind of think that the USB issue and the hanging issue are somehow related Ė but Iím not sure.

Iíve cleaned out a lot of my programs (in case that caused the hanging). I still need to disable useless programs in the system processes.

So, I was compelled to run Combofix in hopes that it would ID some covert Trojan. Iíve attached the Combofix log. Please let me know what else I need to send you and what I need to do to correct the problem. I promise Iíll wait for a response before I take a next step on this. Thanks!

Since running Combofix... which reminds me :P

Please note: ComboFix is an extremely powerful tool which should only be used when instructed to do so by someone who has been properly trained. ComboFix is intended by its creator to be "used under the guidance and supervision of an expert." It is NOT for private use. Please read Combofix's Disclaimer.

Using this tool incorrectly could lead to disastrous problems with your operating system such as preventing it from ever starting again.

...what symptoms have you experienced?

I know, I know...but I was going crazy with my computer freezing up!

I still have the problem with 6 of the USBs installed in the computer. To the one USB that still works, I've hooked up one USB 4 port hub and that works OK. But the 6 others still donít work.

Also, since running ComboFix the computer still hangs - BUT, it doesnít time out like it did previously.

Thanks,
MRVF

At first glance it looks like the USB problem may well be separate to the malware. Combofix removed Search Toolbar and so we need to make sure that you are clean first before we see what symptoms remain.

Run aswMBR, for rootkit detection

Please download aswMBR ( 511KB ) to your desktop.
  • Double click the aswMBR.exe icon to run it
  • Click the Scan button to start the scan
  • On completion of the scan, click the save log button, save it to your desktop and post it in your next reply.


Then please run Combofix again but uninstall the copy you have as it is now out of date.

Uninstall ComboFix
  • Disable any realtime antivirus or antispyware programs.
  • Please press the Windows Key and R on your keyboard. This will bring up the Run... command.
    (For Vista/Windows 7 please click Start -> All Programs -> Accessories -> Run)
  • Now type in Combofix /Uninstall in the runbox and click OK. (Notice the space between "Combofix" and "/")
  • Please follow the prompts to uninstall Combofix.
  • You will then receive a message saying Combofix was uninstalled successfully once it's done uninstalling itself.
This will uninstall Combofix and anything associated with it.

If it fails then just delete the .exe file.


Now download from one of these links

Please download ComboFix from one of these locations:
Then run it and post the new log.

Hi - and thank you.

I will not be able to run all the processes until Sun. But I was able to do the first step. I will post again as soon as I complete the new install and run of ComboFix.

1. Close any open browsers.

2. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

3. Open notepad and copy/paste the text in the box below into it:

RegNull::
[HKEY_USERS\S-1-5-21-448539723-1326574676-725345543-1003\Software\Microsoft\Windows\CurrentVersion\Shell Extensions\Approved\{74193037-8F48-0F1A-438F-87B0292A141A}*]


Save this as CFScript.txt, in the same location as Comfix.exe (called ComboFix.exe in the below graphic)


Posted Image

Refering to the picture above, drag CFScript into ComboFix.exe

If the program requests for you to update Combofix then click Yes.

When finished, it shall produce a log for you at C:\ComboFix.txt which I will require in your next reply.

Here is the ESET file. It looks like the program scanned through my external file (F: drive), too. That's good because I was going to ask you if I should clean that as well? I thought I may keep reinfecting my hard drive and I certainly don't want that to happen! I notice that a couple of the infected files ESET scan caught are within my SpyBot scans.

I also wanted to ask you if I should delete my restore points? If they have files previous to the ComboFix and ESET scans wouldn't they keep reinfecting my hard drive if I need to restore my computer to an earlier time?

Thanks again for all your time.
How should I proceed next?

We will deal with the restore points soon, don't worry.

The Seagate seemed to have been infected so there could have been an element of reinfection going on.

How is the machine running now? Any problems left?

Except for the USBs it seems good! It was hanging at first so I disconnected the external drive (Seagate) just in case and ran defrag on the hard drive. Now it is much better!

Did the ESET clean the external drive and I don't have to worry about reinfecting now?

Thank you again!

Yes, ESET cleaned your external, it's a very thorough and extremely good online scanner - it does take some time though.

Let's do the clear up now, restore points and various tools will be dealt with here.

You're clean. Good stuff! :thumbup2:

Let's do some clearing up

If you used DeFogger now is the time to enable your CD emulation software again.

Uninstall ComboFix

Remove Combofix now that we're done with it.
  • Please press the Windows Key and R on your keyboard. This will bring up the Run... command.
    (For Vista/Windows 7 please click Start -> All Programs -> Accessories -> Run)
  • Now type in Combofix /Uninstall in the runbox and click OK. (Notice the space between "Combofix" and "/")
  • Please follow the prompts to uninstall Combofix.
  • You will then receive a message saying Combofix was uninstalled successfully once it's done uninstalling itself.
This will uninstall Combofix and anything associated with it.


We Need to Clean Up our Mess
Download and Run OTC

We will now remove the tools we used during this fix using OTC.

  • Download OTC by OldTimer and save it to your desktop.
  • Double click Posted Image icon to start the program. If you are using Vista, please right-click and choose run as administrator
  • Then Click the big Posted Image button.
  • You will get a prompt saying "Being Cleanup Process". Please select Yes.
  • Restart your computer when prompted.
If you still have any tools or logs leftover on your computer you can go ahead and delete those off of your computer now.
------------------------------------------------------------------------------------------------------------------------

Here's some advice on how you can keep your PC clean


Use and update your AntiVirus Software

You must have a good antivirus. There are plenty to choose from but I personally recommend the free options of Avast and Avira Antivir - though if you choose Avira you should make sure that you uncheck the box offering to install the Ask toolbar. If you want to purchase a security program then I recommend any of the following: AVG, Norton, McAfee, Kaspersky and ESET Nod32.

It is imperative that you update your Antivirus software at least once a week (Even more if you wish). If you do not update your antivirus software then it will not be able to catch any of the new variants that may come out. If you use a commercial antivirus program you must make sure you keep renewing your subscription. Otherwise, once your subscription runs out, you may not be able to update the programs virus definitions.


Make sure your applications have all of their updates

Use this next program to check for updates for programs already on your system. Download Security Check by screen317 from here or here.

  • Save it to your Desktop.
  • Double click SecurityCheck.exe and follow the onscreen instructions inside of the black box.
  • A Notepad document should open automatically, make sure that updates on any that are flagged are carried out as soon as possible

It is also possible for other programs on your computer to have security vulnerability that can allow malware to infect you. Therefore, it is also a good idea to check for the latest versions of commonly installed applications that are regularly patched to fix vulnerabilities. You can check these by visiting Secunia Software Inspector and Calendar of Updates.


Install an AntiSpyware Program

A highly recommended AntiSpyware program is SuperAntiSpyware. You can download the free Home Version. or the Pro version for a 15 day trial period.

Installing this or another recommended program will provide spyware & hijacker protection on your computer alongside your virus protection. You should scan your computer with an AntiSpyware program on a regular basis just as you would an antivirus software.


Finally, here's a treasure trove of antivirus, antimalware and antispyware resources


That's it, it appears that the USB issue isn't connected to the malware as that is still causing problems. I suggest posting in the XP forum or perhaps the external hardware forum. Good luck.

Cheers.
