Random Trojans and Malware?
« on: February 17, 2011, 07:01:39 PM »
Hi everyone, I recently got a virus from attempting to download a game save file from a questionable website, although I am relatively sure that I got rid of it, and now I am getting occasional Malware or Trojan pop-ups from Avast! at random saying that it has blocked a Malware or Trojan. Sometimes my computer will drastically slow down and I will have to do a scan and get rid of a Malware or Trojan, and I can't figure out where I am getting them! I have only gone to very secure and high-trafficked websites since my battle with the virus, but I'm wondering if perhaps there is still some sort of remnant from the virus that has left my computer open to attack... can anyone help or think of something I could do to check for something like this?

Try this

http://www.geekstogo.com/forum/files/file/187-tfc-temp-file-cleaner-by-oldtimer/
TFC requires a reboot immediately after running. Be sure to save any unsaved work before running TFC.


Malwarebytes Anti-Malware 1.50.1  http://filehippo.com/download_malwarebytes_anti_malware/
Always update the program so you have latest database before you scan
Click the remove selected button to quarantine any infections found

If anything is found, please post/attach the scan log here

So I am currently running the Malwarebytes scan and it's not done yet, but so far it says I have 13 infected files, and I'm not quite sure how to post the scan log, so I figured I'd just ask in advance so I could do it right when the scan finishes.

Did you also clean your temp files ?

Is your problem now solved?

I did clean my temp files and ran the scan and deleted all the pesky malware, and I believe the problem is solved (Knock on wood) but if it starts happening again for no apparent reason then I'll say so.

Hmm... My computer seems to be running up to speed and everything, but Avast! keeps notifying me every now and then that it has blocked a Malicious object. The reason I'm mentioning this is because it will say this when I'm on a perfectly harmless site, or even when I am just on my desktop with nothing running at all, and it is making me very nervous that these supposedly malicious objects are just appearing out of nowhere, is there any way I can test to see if there is some sort of trace or something on my computer that allows these malicious files to try and enter when that shouldn't even be possible?

Follow this guide from our expert malware remover Essexboy

To avoid using multiple post with copy and paste you have to attach the log`s

Alright, well I went through a whole gauntlet to fix it (Did a system restore, then ran a Malwarebytes scan, then did a Temp file cleanup, then did another scan and temp file cleanup for good measure) and I hope it's gone, I can't figure out how to attach the log with the "additional options" because I can't find where the logs are kept, so if you'd like I can just copy and paste it onto here

When the scan completes, it will open two notepad windows. OTL.Txt and Extras.Txt. These are saved in the same location as OTL.
So if you saved OTL to your dektop and run it form there then the logs will also be there, and you just browse to that location....

Alright, so I ran the OTL scans you asked for and I really hope you guys can help me with this, I'm getting sick of these stupid malwares that won't go away and are slowing down my computer, and thanks for the help you've given so far.

And if it helps at all, when I check on my task manager under "Processes", there's a process called "svchost.exe" that occasionaly flares up and pretty much runs my computer to a standstill so that I have to close everything and wait for it to speed up again, and even when it isn't "acting up" it still takes on average over 120,000 kilobytes, which I assume is bad. (At the moment I'm playing a game called "Minecraft" and scvhost.exe is using approximately 660,000 kilobytes...

Here's the "OTL" and "Extras" logs:

Nothing is showing on that scan - however, the svchost level is a bit high

Lets run a check for weird drivers

Download ComboFix from one of these locations:


Link 1
Link 2


* IMPORTANT !!! Save ComboFix.exe to your Desktop


  • Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools
  • Double click on ComboFix.exe & follow the prompts.
  • As part of it's process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. With malware infections being as they are today, it's strongly recommended to have this pre-installed on your machine before doing any malware removal.  It will allow you to boot up into a special recovery/repair mode that will allow us to more easily help you should your computer have a problem after an attempted removal of malware.
  • Follow the prompts to allow ComboFix to download and install the Microsoft Windows Recovery Console, and when prompted, agree to the End-User License Agreement to install the Microsoft Windows Recovery Console.
**Please note: If the Microsoft Windows Recovery Console is already installed, ComboFix will continue it's malware removal procedures.




Once the Microsoft Windows Recovery Console is installed using ComboFix, you should see the following message:




Click on Yes, to continue scanning for malware.

When finished, it shall produce a log for you.  Please include the C:\ComboFix.txt in your next reply.
