Another Win32:Malware-gen

Viruses and worms
1

Hello, I have been having some trouble dealing with a Win32:Malware-gen. I noticed it yesterday when my copy of Microsoft Security Essentials stopped working; it also appears to have disabled Windows Firewall. Anyway, I installed a Trial of Avast Internet Security and it has been popping up saying that it blocked the malware, and also a Trojan I didn’t know about, (Win32:DNSChanger-VJ [Trj]) from interfering with my processes.

Avast is unable to remove it, as is the trial of Malwarebytes I installed. Could someone give me advise on how to remove these viruses. Any help is appreciated!

I’m having the exact same problem! I’ve been trying to wrap my head around it and fix it for 2 days straight. I’m not computer savvy by any means so I’ve just been running scan after scan.

The worst part is that I can’t get anything to move to the virus chest. My options end up being either doing nothing or deleting what gets found. Avast has detected well over 100 corrupted files since the notifications began and I won’t be surprised to find more. I’ve run two boot-time scans, two quick scans, a full system scan and numerous scans of the C:\ folder. I can’t figure any of this out and I don’t know what to do.

Somebody please help!

[Edit] Avast has detected over 500 infections since this first started happening. I’ve just been deleting everything since I can’t seem to get anything into the virus chest. It keeps displaying an error saying the virus chest server is down.

@YoHodge you need to start your own topic, helping multiple users in the same topic will only be chaos
corrupted file(s) are just a scan error report and not detection…so avast will take no action

@Kobalt

follow this guide and attach (not copy and paste) logs from malwarebytes / OTL / aswMBR

@Pondus

Thanks for replying, but I have already removed it. :slight_smile:
I found someone over at Major Geeks that had the exact same problem,
so I just followed their posts till I figured out how to get rid of it.

ok…but if you attach the logs requested, Essexboy can see if you got it all…
and he usually find some leftovers. :wink:

I’m going to have to double post this because the files are to big.

Here is the malwarebytes and aswMBR logs.

And the OTL log.

I already looked them over, but I want to make sure I haven’t missed anything. :slight_smile:

It has actually been a bit sluggish lately, but the speed does seem to have improved after that last scan.
Here is the log file as requested.

One more to kill, how is it now any more alerts ?

No. I have not received any alerts since running combo fix, and Windows Firewall is back up and running. :slight_smile:

Here is the log from OTL

12

Ok if you could run as normal for the next day, and if all is good I will remove my tools and tidy up

13

Alright, everything seems to be running normally again. My latest scans with avast and Malwarebytes have both come back clean.

14

Subject to no further problems :slight_smile:

I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems

Now the best part of the day ----- Your log now appears clean :thumbsup:

A good workman always cleans up after himself so…The following will implement some cleanup procedures as well as reset System Restore points:

Run OTL
[*]Under the Custom Scans/Fixes box at the bottom, paste in the following

:Commands [resethosts] [emptytemp] [Reboot]

[*]Then click the Run Fix button at the top
[*]Let the program run unhindered, reboot the PC when it is done

Remove ComboFix

[*]Hold down the Windows key + R on your keyboard. This will display the Run dialogue box
[*]In the Run box, type in ComboFix /Uninstall (Notice the space between the “x” and “/”) then click OK

http://i1224.photobucket.com/albums/ee362/Essexboy3/Misc%20screen%20shots/CF_Uninstall-1.jpg

[]Follow the prompts on the screen
[]A message should appear confirming that ComboFix was uninstalled

Run OTL and hit the cleanup button. It will remove all the programmes we have used plus itself.

We will now confirm that your hidden files are set to that, as some of the tools I use will change that

[*]Go to control panel
[*]Select folder options (Appearance > Folder options in category view)
[*]Select the View Tab.
[*]Under the Hidden files and folders heading select Do not show hidden files and folders.
[]Click Yes to confirm.
[]Click OK.
