Hi guys,

 

My Windows7 box is infected with "username.exe". Chronological details follow:

 

I downloaded a bad torrent a few days ago, didn't notice it was an .exe file (such a n00b mistake, i know)

I ran scans via MalwareBytes (free version) it did not detect anything (all drives selected, updated database, scanned for rootkits as well)   

Later I noticed a process with my username with a .exe in my taskmanager, hogging up all processor usage. I traced it to the AppData/Roaming folder and found two encrypted .exe files

I downloaded Panda antivirus realtime protection and ran it. It found a virus called "amde.exe" and told me to reboot as it would attempt to delete it

When I tried rebooting, my Windows7 kept freezing on the startup screen and would not run

I went into Safemode and restored my OS to a previous version

It is now stable, I have both the username.exe files blocked via Comodo firewall, but I have NOT deleted them as I think that might make my system unstable again

I have since logged numerous events in my firewall of this username.exe attempting to modify files, although it seems to quiet recently

I've searched for the username.exe files on all of my other harddrives, but it's only present on my C drive

It also tries to copy itself into my startup folder but I keep removing it from that folder manually

 

How do I safely remove this thing without making my system unstable, or completely re-installing Windows?

 

 

Relevant Intel:

Windows 7 64 bit

Comodo Firewall 7.03 (free version)

MalwayreBytes Anti Malware (free version, no real time protection)

Location of Trojan: C > Users > Username > AppData > Roaming

 

Both files with 2 usernames look like winzip files (even though they are .exe) and are encrypted (password protected). I can still open both the files with a Vim Editor, but the code inside is ineligible. 

 

 

p.s. I know I should have realtime protection, but my previous free antivirus program wouldn't let me run Virtualbox so I had to uninstall it. Installing Panda after infection clearly didn't work.

p.p.s. I downloaded TCPView and have been monitoring my internet activity. I have not noticed these files establishing outbound/inbound connections.... It's possible Comodo is effectively blocking the programs (at least they are not showing in taskmanager anymore). But maybe the programs have hijacked some other Windows system process and using it to communicate.

If no one knows how to manually remove it, can someone at least please tell me if it's safe to keep this trojan on my C drive if I have blocked it via my firewall?
 
I can wait until MalwareBytes eventually includes it in its database...

Hello this is a worm infection.

It would be better to get a deeper look and see all its hooks.

Please follow this Preparation Guide, do steps 6,7 and 8 and post in a new topic.
Let me know if all went well.

Thanks boopme

 

I've followed the steps and posted a new topic "Username.exe worm removal" in malwayre removal logs section

 

However, I had to attach both the DDS outputs, because I can't seem to copy/paste anything in this forum from my Chrome browser

Thank You!!

Now that your log is properly posted, 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 Malware Removal Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it 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 Malware Removal 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 Malware Removal Team members are very 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 Malware Removal 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 MRL Team member is already assisting you and not open the thread to respond.
The current wait time is 1 - 5 days and ALL logs are answered.
If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.
To avoid confusion, I am closing this topic.
