Hi all, a few months ago, after using a friend's flash drive to transfer some files onto my laptop, I realized I was infected with some sort of malware. I scanned my computer with Ad-Aware Free Edition and Spybot S&D and removed the problematic files they listed. After that, everything went back to normal except for an annoying "Can not find script file "C:\Windows\boot.ini" error prompt when I start up my computer. I usually press Okay and it goes away so I leave it alone.

Two days ago, I accidentally opened a file that is actually some sort of malware. After clicking on it, Windows Defender gave me a warning message saying that it found something (can't remember exactly what it said) and it requested to run a scan. After the scan, it removed one file, but then I proceeded to scan with Ad-Aware and S&D. After removing the files those programs found, some weird things started happening to my computer. First of all, it would run slower than usual. I checked the Performance graphs in Windows Task Manager and my CPU Usage would fluctuate up to 90% even if I don't have any windows opened. There would be random pop-ups when I surf the web with Firefox, and sometimes a random "D:" drive would pop up even though I don't have my external HDD turned on. I also can't modify my folder settings to see hidden files.

After some googling, I downloaded another program called "RegRun Security Suite" and it removed some more files for me, but my computer is still running noticeably slow and the Performance graphs are still fluctuating. Although I have yet to see a random popup from Firefox or the elusive D: Drive again...

I don't know if this would help, but some of the files that were identified by S&D and RegRun were named "sdrgfcvbf.dll," "PWS.LDPinchIE," ".MGT_reg32.dll.vbs," "qgc33ej0ega5.exe," "P2HHR.bat," and "gjbtnb.exe." I googled these and most of the results say these are bad files to have :thumbsup: BTW I'm running Vista Home Premium with Service Pack 1.

I'm sorry if I'm not providing the enough information but this is my first time posting, and I'm trying to supply as much information as I can recall (like what the sticky thread said to do) If you need more information just ask, I'll be more than happy to comply.

Thanks!

One of the files you listed is a "backdoor trojan" (.MGT_reg32.dll.vbs). See info in link below to help you decide
whether you should do a clean reinstall of the software on your computer or not.
http://www.dslreports.com/faq/10063

If you decide not to reinstall, run scans from both Super Antispyware Free and Eset online scanner.

SAS instructions and download link:
http://www.bleepingcomputer.com/forums/ind...t&p=1040160

Eset Online Scanner:
http://www.eset.com/onlinescan/index.php

Post the logs from both scans and for further instructions.

@ buddy215: Thanks for your reply. I checked the first site you gave me and I believe it's better if I just remove the virus instead of formatting and reinstalling Vista. I ran SAS and ESET like you instructed, here are the logs from them.

@ xblindx: Thanks for your reply and detailed instructions. I saw your post after I ran SAS the first time, but I followed your instructions with scanning in Safe Mode and used ATF-Cleaner as well. The log from the SAS scan is below.

After these scans, Windows Task Manager is showing my idle CPU Usage to be back to normal. I still get that warning prompt ("Can not find script file "C:\Windows\boot.ini") when I boot up to Windows for the first time. Anything else I should do?

I'm really appreciating the help from you guys, thanks a lot!

P.S. - After using Firefox with some basic Google searches, I noticed that the browser is unusually slow. If I leave it alone while I'm reading a web page, the mouse cursor would randomly turn into a loading cursor for a few seconds and the browser wouldn't respond.

The error suggests malware and an orphaned entry in startup.

Download Autoruns from Microsoft to your Desktop.

http://technet.microsoft.com/en-us/sysinte...s/bb963902.aspx

Extract the Autoruns Zip file contents to a folder. Double-click
"Autoruns.exe". Click on the "Everything" tab. Remove any entries that
mention "File Not Found" by right-clicking the entry to select Delete.

Next run a scan with MalwareBytes AntiMalware. Directions and download link below.
http://www.bleepingcomputer.com/forums/ind...t&p=1100727

Scan your computer with SDFix.

I downloaded Autoruns, removed entries that said "File Not Found," but the start up error message is still there. Weird thing is that when I check Autoruns again, something named "winboot" under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run keeps appearing each time I delete it and reboot.

I also scanned with Malwarebytes AntiMalware and here's the log:

Files Infected:

When I chose to remove the files, it said some of the files could only be removed after a reboot, so I clicked okay. When my computer launched Windows again, another software I use called "RegRun" started scanning my computer before MalwareBytes' AntiMalware could start. Could that be a potential problem? I ran another scan after that and it said there were not threats found, but I'm not sure if it were able to delete the files it wanted.

After that I tried running SDFix, but the window keeps appearing and disappearing when I launch the program. I followed the instructions in the link you gave me about typing in "%systemroot%\system32\cmd.exe /K %systemdrive%\SDFix\apps\FixPath.exe" and rebooting my computer into safe mode, but it's still not working.

Thanks again for your reply.

Whether the damage can be repaired or not by the Hijack This Team, I can't say. That is your best option
other than reinstalling. I really think though, that you should reinstall.

Follow the directions below for posting in the Hijack This Forum. Once you have started your own topic do
not bump it. Wait for one of the team members to respond.

Thanks for your suggestion buddy215. I went to the link you posted and the first step mentions backing up data. I was wondering if it was safe for me to use my external hard drive on this infected system before I started moving files to it.

That should be okay as long as you don't transfer any .exe, etc. Without knowing exactly how the original
malware got on your computer, such as email attachments, music, movies, etc. that you recently downloaded would
be suspect and shouldn't be saved to any external device.

Good luck to you and if you need assistance in reinstalling start a new topic in the Vista Forum.

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/227485/infected-with-backdoor-trojan-mgt-reg32dllvbs/ you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a HJT Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the HJT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond. Please be patient. It may take a while to get a response but your log will be reviewed and answered as soon as possible

To avoid confusion, I am closing this topic. Good luck with your log.

Orange Blossom :thumbsup:
Help us help you. If HelpBot replies, you MUST follow step 1 in its reply so we know you need help.
