My system specs:

 

Operating system: Windows 8 64-bit (6.2, Build 9200)

System manufacturer: ASUSTeK COMPUTER INC.            

System Model: K56CA

BIOS: K56CA.206

Processor: Intel® Core™ i5-3317u CPU @ 1.70GHz (4 CPUs), ~1.7GHz

Memory: 6144MB RAM

 

The first time I noticed trouble was Thursday. As  I was searching for someone on Facebook, Firefox would crash. If I reloaded Firefox and went to Facebook to do the same, it would crash again. I don’t remember every event after this, but I then encountered problems where I would try to open any program, even windows explorer, and I would get popup messages saying something about dll error, or something about not having a valid image.

 

I thought I was infected at this point so I ran avast free virus scan; after only a few minutes in it said it had found about 171 infected files. I then clicked on the statistics button in avast and the entire thing froze up. Then my computer froze up, so I had to force it to shutdown by holding down the power. I had to do this a few times before I was able to finally get in and run avast again. The thing is, this time it did a complete scan and said it found ZERO infected files. Why would it say it found some initially, freeze up, only to find none the next time?

 

I Thought I was out of the woods, so I bought the full version of avast to better protect myself in the future. Only to later find I was still having these dll error messages pop up.

 

I later began experiencing a blue screen that said something about my computer having problems and that it did not shut down properly, the blue screen led to my computer running some kind of scan to repair.

 

Over the next few days I ran malwarebytes, avast, cccleaner, combofix.(I know, I did this before reading this site)  Still no serious improvement.

 

I was able to do a system restore yesterday.

 

Last night when I went to shutdown my computer, it would almost shut down, only to force a restart. This process was never ending. I tried to uncheck the fast start option; still no solution. I ended up updating some qualcomm driver which then allowed my computer to fully shutdown.

 

Thinking all might be well, I woke up this morning to turn on my computer. When I turned it on and logged in, the screen was flashing. There were no desktop icons or desktop background, just a blank background with the taskbar showing and constantly blinking on and off. I was able to start task manager an d saw that Malwarebytes was using a lot of resources so I forced it to end and the blinking stopped and I was able to restart and log in normally.

 

I don’t understand why these scanners are finding no infections, and yet I continue to have these problems.

Hi,

 

Since you have run Combofix, please follow these instructions:

 

Please follow the instructions in THIS GUIDE starting at Step 6. If you cannot complete a step, skip it and continue.

Once the proper logs are created (make sure to include the combofix log created, probably located at C:\ComboFix.txt), then make a NEW TOPIC and post it HERE. Please include a description of your computer issues, what you have done to resolve them, and a link to this topic.

If you can produce at least some of the logs, then please create the new topic and explain what happens when you try to create the log(s) that you couldn't get. If you cannot produce any of the logs, then still post the topic and explain that you followed the Prep. Guide, were unable to create the logs, and describe what happens when you try to create the logs.

It would be helpful if you post a note here once you have completed the steps in the guide and have started your topic in malware removal. Good luck and be patient.

If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/521416/missing-dll-errors-and-system-crashesblue-screen/ 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.

If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.

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