C:Windows\assembly\tmp\U\80000032.@ - Win32:DNSchanger-VJ[Trj]

Viruses and worms

So Avast keeps spamming me with this problem, something at C:Windows\assembly\tmp\U\80000032.@ is trying to do something to GoogleUpdate.exe and Chrome.exe. Not a great explanation, I know, either way Avast seems to block it but each time it does it wants me to perform a boot-time scan. I am also getting this type of warning:
URL: http: //50.7.245.170/RAI05SE6R5x1Tu1NDIxf…
Process: file://C:\Windows\System32\svchost.exe
Infection: al

Something is obviously trying to get me into more trouble here.

It seems to have disabled my Windows Firewall and it won’t let me start it up again, googled the hell out of that one but nothing I could find would solve my issue with that.

Now I tried the boot-time scan but it takes forever (The first 2% took an hour, didn’t feel like waiting that one out), so I let it sit over the night. When I woke up it was finished, it had found something called nye22.dll and it was asking me how to deal with it. I tried every option but the computer seemed to have frozen at some point, delete, repair, nothing worked. So today I’ve spent the day running Malwarebytes, SUPERAntiSpyware, CCleaner, Full system scan with Avast and TDSSKiller, yet I’m still having the issue. I’ve run out of ideas, there’s going back and running the boot-time scan and hoping that’ll do it, or randomly jumping into ComboFix which seems to be what all the pros use to fix this type of stuff. I figured I’d just come here and ask for some help before I break something. So, here’s the logs:

OK this one looks like the zero access or conserv infection and will require the help of a malware removal specialist for your OTL logs (I’m not familiar with them). Essexboy who normally deals with these isn’t on-line until around 7pm UK time, now almost 11:20am.

The aswMBR log looks fine though.

EDIT: Strange that the IP address is also Sweden, see image, does this ring any bells ?
The IP is also linked with spamming and is on an HTTP BlockList.

I’m afraid not, I did have an issue a couple of months ago where someone in my contacts list recieved an email supposedly from me, that I did not send. Did the whole scan routine back then, came up blank, and changed my passwords. Not sure if that’s relevant, figured it might be since you said spamming.

It isn’t unusual to get such emails purporting to have received an email from you when you haven’t sent it.

If you use web mail (hotmail, etc.) there is a possibility that your account may have been hacked. But if you use normal email using something like thunderbird to send and receive, it is unlikely you sent it as avast would also be on the lookout for multiple identical emails (spam) if you have the mail shield set to High.

The most likely reason is that someone who you communicate with has an infected system and their email address list is being used to send spam to and also to fake the from email address.

They also frequently use the same To and From email address as most peoples email filters would allow your own email address through unmolested (white-listed).

However, that said I don’t believe this is connected.

No sir, no problems at all. In fact the Windows Firewall is up and running again. Did an MBAM scan, didn’t find anything:

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:

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

[*]Click Start.
[*]Open My Computer.
[*]Select the Tools menu and click Folder Options.
[*]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.
