Earlier today, my home computer became infected with a couple trojans and some other minimal viruses. I was able to successfully remove them all, but I only say that because that is what MalwareBytes and SuperAntiSpyware are telling me. Since then, my computer has been lagging more than I am used to, and I got a strange pop-up about an error message to "Send" or "Do Not Send." I forgot to take a screencap because I wasn't sure at the time as to what it was, but when I clicked to see the details, it was talking about my IP address and passwords. I simply clicked "Do Not Send," restarted my computer, and scanned it again. I also ran rkill, and there were more stopped processes than normal, but I'm not sure if they were part of my computer programs or not. Here is the list:

C:\DOCUME~1\Owner\LOCALS~1\Temp\Cpl.exe
C:\Documents and Settings\Owner\Local Settings\Application Data\asam.exe
C:\WINDOWS\system32\netsh.exe
C:\WINDOWS\system32\netsh.exe
C:\WINDOWS\System32\imapi.exe


This is my third time getting trojans in the past month. I've been searching online and read somewhere that sometimes backdoors can lead to you getting the virus again, even when you think it's gone. I don't have a lot of knowledge about it, so I just wanted to post here to see if I'm in any danger and/or what I should do to prevent them in the future. Thank you in advance.

edit//
MalwareBytes just picked up a threat - Trojan.FakeAlert.
I spotted this earlier, but thought it was removed. I guess not.

Hello, I am leaving here now but will look back tomorrow. What we see here indicates probable backdoors,worms and dialers.
Yes backdoors present a serious security risk.

Please run these...
FixExe.reg

FixExe.reg
....click Run when the box opens

TFC by OT
Please download TFC by Old Timer and save it to your desktop.
alternate download linkSave any unsaved work. TFC will close ALL open programs including your browser!
Double-click on TFC.exe to run it. If you are using Vista, right-click on the file and choose Run As Administrator.
Click the Start button to begin the cleaning process and let it run uninterrupted to completion.
Important! If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway to ensure a complete clean.
Rerun MBAM (MalwareBytes) like this:

Open MBAM in normal mode and click Update tab, select Check for Updates,when done
click Scanner tab,select Quick scan and scan (normal mode).
After scan click Remove Selected, Post new scan log and Reboot into normal mode.


Now run GMER:
Please download GMER from one of the following locations and save it to your desktop:
  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.

    Posted Image
  • GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.
-- 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

Ok, let's see what GMER says. Then we'll decide where to go next.

Okay, I followed the steps, but whenever I try to post the DDS and old GMER log, the DDS one gets cut off and cuts off the entire post. I'm not sure what to do.

Perfect :thumbsup:
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 HJT Team member is already assisting you and not open the thread to respond.

To avoid confusion, I am closing this topic.
