Hi guys!

First time post here. I've been having major application errors of "wuauclt.exe" for the past few days. The error message comes up during startup and repeats itself many times. I had to click OK or Cancel for 10+ times, it's getting really annoying.

I disabled automatic update and it made the error message less freqeunt during computing, but it still happens everytime I turn on/off my PC. The computer is also getting slow, like a moving a mouse cursor would appear choppy across the screen.

I haven't finished running GMER, as it probably will take overnight to finish since it already failed twice when my PC got too slow and had a blue screen of death. I ran MalwareBytes Antimalware and Trendmicro Housekeeping (or whatever name it was), both gave clean bill of health.

Anyways here's the error message:

The instruction at "0x77c47380" referenced memory at "0x142b000". The memory could not be "written".
The "0x142b000" term can be subsituted with:
0x0142b000, 0x0142d000, 0x0142e000, 0x0142f000
0x01426000, 0x01427000, 0x01430000, 0x01432000, 0x01433000, 0x01434000, 0x01435000

Any suggestions? Can it be hardware error, software, malware?
I am running GMER, and I'll post results if necessary.

Thank you very much!

Hi!

Thanks for the help. Unfortunately, the error message still pops up during startup and also computing, and I had no way of shutting it down (even by disabling auto update in from control panels).

However, I don't get the error message in safe mode, what does this mean?
The computer is also getting very slow.

What should I do next?

Thank you!

The memory could not be "written".

and

I don't get the error message in safe mode[...]The computer is also getting very slow.

Some infection very possible.
I suspect, ordinary removal tools may be not enough, so....

With the information you have provided I believe you will need help from the malware removal team. I would like you to start a new thread and post a DDS log HERE and include a link to this thread. Please make sure that you read the information about getting started before you start your thread.

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. Help is on the way!

Hi Broni

Thanks for the quick reply. I'll run DDS,since it seems fast, but I am wondering should I run GMER, and in which mode should I run it? Safe mode or regular startup? I already tried GMER twice in normal startup mode before posting here: one time blue screen appeared when I opened another window (probably due to the computer becoming too slow and unstable for multiple tasks) and another time memory error occurred after GMER scan finished, so I wasn't able to save the log (I forgot what the error message was). I have about 500,000 files total, and I'd imagine it would take at least overnight to run GMER completely.

Do you think I should run it in safe mode? Whatever you suggest I'll run it and then post in malware removal forum.

Thank you!

You should rather ask those questions in malware forum.
I really don't have an authority to advice you on malware issues.

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/topic390917.html 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.
