Sometimes the malware just spams the “enter” key.

If I double click on a shortcut on my desktop, the malware will press enter all the time, making the program start many times. It makes writing of any kind VERY hard. This includes passwords and searches. Sometimes when I scan with mbam the malware will press enter many times, making it start and abort scans all the time.

However, what worries me most is that I did a clean Linux Ubuntu install, and it too has the same problems as my Windows XP. When I enter the GRUB OS loading menu I sometimes can’t use the OS I want, because the malware press enter.

There is a strange “ticking” noise (not beeping) some times when I start my PC. I think it happens because of the malware pressing enter all the time. I have never heard the sound before I got the malware.

I have tried using AVG, CCleaner, Malewarebytes Anti-Maware, and finally ComboFix. Each one of these encountered some malware, and when I remove it the problems stop for a while. The next day (or after a reboot) the problems may be back. I also have tried BlackLight, but it found nothing. I have tried GMER, but my PC crashes and my screen freezes before it is able to finish.

I am using Windows XP Home Edition SP3. I am unable to install the Windows Recovery Console with my Windows CD (sp2 i think) or from the internet or with ComboFix.

Any help would be greatly appreciated

Just to be sure, have you tried using a different keyboard?

I bought a new keyboard while this was happening, and I don't think it has something to do with the physical keyboard. The next time it happens i will unplug it, just to see if the problems continues to persist.

If the effect stops when the keyboard is not plugged in, there's a fair chance it's the keyboard (or maybe the keyboard controller if it's a PS/2 keyboard, but I'm not sure whether to think the motherboard controller could generate key codes of its own accord). Proving it is a process of elimination (try another keyboard, or use that keyboard on another computer).

Is it a PS/2 keyboard? If so, remember some motherboards can be damaged by plugging & unplugging PS/2 keyboard or mouse whilst powered up.

To eliminate the controller, the only way I can think of is to try a keyboard of a different connection type, eg try a USB keyboard if the present one is PS/2.

Hello. We should review your ComboFix and an HJT/DDS log.


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. Include the ComboFix and GMer logs ( if it works see below)
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.



NOTE:

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.

It went fine except a little trouble with GMER:
The first scan with GMER (normal mode) resulted in a BSOD, which said this:

PFN_LIST_CORRUPT

***STOP:0x0000004E (0x00000007, 0x0007C41C, 0x00000001, 0x00000000)

GMER worked in Safe Mode tho, but took like 3 hours to complete.

Here are the logs:

Yes, it is PS/2, but i have not used it for very long and i haven't unplugged it while the PC was running except for this one time.
The next time i get these problems i will do some more testing with my old usb keyboard.

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/297949/malware-spams-enter/ 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.

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