After running malware and avast scans, the one file I can't delete is one in my system 32 called yyykv.sys. Malware bytes says it deletes it and after I restart its still there. I dont know what to do and I am quite scared because a lot of my school work is on my laptop and I can't afford to buy a new one. Please, help me with this malware/virus!

Sorry for the late response. I have done what you said and did another malwarebytes scan just to be safe. After restarting computer, I still get an alert claiming a yyykv.sys in my system32/drivers folder is a rootkit and I "delete" with avast but its still there. Below is my malware and super anti spyware logs.

OK, let;s see if GMer reveals that Kit.
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

Ok, I have scanned my computer with that but I had to do it in safe mode. Also whenever I restart my computer, I always get 2 or 3 windows claiming a dll is missing or something. Also, recently, when I log in my computer shuts down and goes into a "blue screen" and scans my hardware for somethings. Its relatively quick and I can restart but I am becoming more worried. Also, my log is quite big so I might end up posting several posts but its just one log.

I will upload the file to like medafire.com because I can not post the entire log and it would take liek 10-15 posts to post all the data. I apologize for the inconvenience because I know you are working hard to help me. I doubled posted it because I started to post the log but then edited it because it was easier to upload it online. If there is another way to do it please inform me but I think it would be confusing to post 10-15 posts about the log. Again thanks.

Hi, these infections require specialized tools.. I need you to repost that GMER file above and your HJT log here...


You will need to Download and Run DDS which will create a Pseudo HJT Report as part of its log..
If for some reason you cannot perform a step, move on to the next.
Please follow this guide. go and do steps 6 thru 8 ,, Preparation Guide For Use Before Using Malware Removal Tools and Requesting Help . Then go here Virus, Trojan, Spyware, and Malware Removal Logs ,click New Topic,give it a relevant Title and post that complete log.

Let me know if it went OK.

I am unable to redo a scan of gmer because my computer just crashes, giving me that "blue screen" and then restarts. Can you tell me how to attach files?

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/298295/infected-with-unknown-malware-please-help/ 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 MRT Team member, nor should you 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 MRT 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 MRT 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 MRT 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 MRT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

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.
