DOS allereon.a virus messed my comp up! Please help me fix!

July 1, 2012 at 04:17:06
Specs: Windows 7
I got this virus last year and am only now finding this website... The virus prevents me from opening any applications besides the program files, like internet explorer and wmp. I'm on a win32 hp pavillion pc because my dad blocked me from using his internet connection on my infected computer, and no he won't help me pay to get it fixed. None of my old virus scans work, and microsofts scanner will only identify the problem. To further worsen my problem, I have accidently changed the default program for using exe programs to external installer... Help!

Can you download Malwarebytes anti malware- http://www.malwarebytes.org/ of another computer, save the setup file and transfer it to your computer, install it and run scans.

Does the virus have any effect in safe mode ( press F8 before windows loads).

I am a hardware guy not a software guy but i try to help.

This one you will want to kill the rootkit first if you are using malwarebytes, maybe rkill? The problem i see is the unavailability of the internet if your service has been stopped. If you can access another computer I would do as the above suggests, with the addition of rkill. both from a pen drive or a cd burn

To restore the EXE file associations get the EXE fix download from here:
http://www.sevenforums.com/tutorial...

You will have to transfer it as given in #2, via a pen drive or a cd burn.

Always pop back and let us know the outcome - thanks

Thanks for the EXE fixer! Back to the original problem, I tried opening the disguised Rkill, and the mbyte setup... No luck, then I tried again in safe mode... No luck. I'm begging to feel hopeless. Any other suggestions?

Did the EXE fix sort out the associations?

Did Rkill and MalwareBytes run, or did they run but not cure or unearth anything?

EXE is fixed. When I try to open up Rkill or Malwarbytes I get the confirmation message about opening it, I choose yes, and then the applications never load.

So I assume you managed to install MalwareBytes, it just doesn't run.

Go to its program folder and find its EXE file which is MBAM.EXE

Try changing its extension from EXE to BAT or CMD or COM. After each change double click the file to see if it will run.

No, sorry... I meant the setup didn't run. The virus prevents anything but program files from running.

Re #8

That sounds odd, usually it is program files that viruses prevent from running. The downloaded setup file for MalwareBytes is a program (EXE) - an install program.

Try changing the extension of the "downloaded file", in exactly the same way as already given in #7 (to BAT or CMD or COM).

If it installs using one of these alternatives but then won't run, change the mbam.exe file extension (in Program Files) in the same way, to see if you can get MalwareBytes to start by double clicking the actual file.

Both the download and the mbam.exe program file are designed so that they will run on any of the alternatives given, in order to circumvent virus activity.

You guys do know I didn't have mbam to begin with, right?

Yes we do know that but you now have the downloaded setup file.

Carefully read my #11, I have editted it to make it as clear as I can.

Sorry about the clarification issue. Now, how do I change the extension?

If you have downloaded the latest version of MalwareBytes, the file, wherever you have put it, should be:
mbam-setup-1.61.0.1400.exe

If it won't install just change the "exe" part (that is the file extension) to look like one of these:
mbam-setup-1.61.0.1400.bat
mbam-setup-1.61.0.1400.com
mbam-setup-1.61.0.1400.cmd

You might have to try all three before it starts installing.

If none of them let it install then the virus has got things well stitched up.

One important thing I should have mentioned. Most folk have their computers set to the annoying default of not showing common file extensions, so you won't see the exe part. The download will just say "mbam-setup-1.61.0.1400" because the dot and exe will be hidden from you.

Before you do #15 above, go to the Control Panel > Folder Options > View and uncheck "Hide extensions for known file types". Best leave it set that way.

If you have already started then edit it to look like one of the three variants given in #15 above - try each one.

As it happens, provided that you are set to show file extensions the only thing that really matters is that it has some sort of name and ends with one of the valid file extensions given (with a dot ahead of it). Anything in front of the last dot will be seen as its name.

See My #16 first - important

I'm in the UK and it's approaching 1 am so I must go.

I'm going to assume (ever hopeful) that you have got MalwareBytes to install.
If it runs then fine, but if it doesn't this is what you do:

Go to Start button > Computer > System drive (usually C) > Program Files.
Find the folder "Malwarebytes' Anti-Malware" open it up and you will see a bunch of files. The one that starts the program is mbam.exe and this is the one you need to change. With all file extension now showing you edit it to read like one of these:
mbam.bat
mbam.com
Mbam.cmd

The one that you chose which allowed Install is the best one to try first. Your desktop shortcut will become invalid but the program should start by double clicking the mbam file you have renamed - try each one.

Err...to rename you right click the file and select Rename from the list.

In #15 I was only saying that at that time it was one 'o clock in the morning and past my bedtime. I was here next day but as it happens I am away for a week starting tomorrow. However there are plenty of other helpers about as you can see from this thread, so keep watching - someone else might join in.
