I have a near fatal problem with my main computer which manifests itself as: 'svchost Application error - the instruction at "0x001a61ae" referenced memory at "0x00000000". The memory could not be written'. I have trawled the net and found this to be a common problem but difficult to fix. I have tried all the solutions I have found, from turning off automatic windows updates to running CCleaner to ATF Cleaner to running REGSVR32 WUAPI.DLL to trying to run Malwarebytes and Sysclean - these last 2 will NOT run even in Safe Mode.
The symptoms of the problem are that my computer is totally unstable but variable: mostly it will not connect to the internet at all but occasionally it connects itself on booting and then appears to be sending and receiving stuff and will not disconnect. If I do manage to connect to the net, start with Google and try to open links in other tabs (using Firefox), I am hijacked to spurious unrelated sites and I often find I cannot open a web-page because it is held up waiting for "Google Analytics".
When trying to work with my usual spreadsheets or Word, mostly I get a shot at opening one application but if I try another it crashes. Some applications will not open at all in normal mode. The computer will hardly ever turn off from the screen but requires the button to be held in. Sometimes I re-boot and find the mouse is working but the keyboard is not - hopeless. I can start in Safe Mode but cannot connect to the net and therefore cannot use e-mail. The error message above appears in Safe Mode, every 30 seconds or so - so the error is not disabled in Safe Mode. And I cannot work properly or print anything in Safe Mode either. So I'm completely stuffed.
I did manage to run a HijackThis scan in Safe Mode and saw under Services 023 a couple of items which were not there in the past, namely "Google Update Service (gupdate) (gupdate) - Google Inc." and "NLS Service (nlsX86cc) - Nalpeiron Ltd. - C:\WINDOWS\system32\NLSSRV32.EXE". When searching for Nalpeiron Ltd I came across a post on this site on 24/06/10 by Moses2112 suggesting that "nalpeiron is a virus?" but unfortunately this post was closed before being fixed. Neither of these 023 items remain fixed when trying to remove them with HijackThis.
So - can someone please help here? I am dead in the water otherwise.

Very disappointed to have had no help here - this situation is critical for me. I see I have been moved to this forum but maybe I just don't tick the right boxes when explaining the problem. If anyone is out there and if it makes any difference, since I posted this I have run GMER in Safe Mode and it says I have a Rootkit problem - which maybe means I should be moved back to the original forum. Who knows. Help somebody please.

It's best if your read /print directions and follow them exactly, we need logs to procede.

You can post a gmer log here and we can take a look at it and try a few tools/tricks.

In the Virus, Trojan, Spyware, and Malware Removal Logs forum there's often a long wait due to the shortage of trained helpers.

If you can wait then just follow the directions and start a new topic there

No. Try not. Do... or do not. There is no try.

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/topic354511.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.
