Computer with Hostile Environment

Viruses and worms
1

I know that I’m new to this but my cousin asked me to help him with his computer because it has become badly infected by a tenacious virus.

System:
-OS is Windows XP Professional Service Pack 3

Possible infection point:
-My cousin downloads music torrent files so I’m led to think that this is how he got infected in the first place. Since I know torrent files are notorious for having some nasty viruses embedded in them.

Symptoms:

  • Creates pop-ups that will open the browser to display either will be a window that says “You won a Walmart Gift card, put in you email on the next page to get,” or it will bring up a fake news webpage that reports faulty news.
  • It will freeze up the computer completely or it may just really slow the computer down
  • It will change the settings on his AV programs to disable them

Observations:
-I’ve taken several steps which Essexboy has instructed me in the past and if needed I will include the logs once they’ve finished
-I’ve use aswMBR, Combofix, and now I’m scanning with Kaspersky.
-I tried using the silentRunner program but it wasn’t running at all, I know that it may seem like it isn’t working but this time I had no prompts at all so I knew it wasn’t running
-While running Kaspersky the first time it found 3 threats and 1 of them was in the memory but then it locked down the computer. What I mean is it let me close Kaspersky but when I tried opening any of the programs I mentioned earlier it said they were invalid files and wouldn’t run them. Also I disconnected the wireless adapter and it still said that it was connected, which is impossible because I took away its access completely to the network with removing the adapter.
-I’m currently running Kaspersky in safe mode on the highest settings because it appears to me that this computer is as some would say a cluster$@#!, you can figure that out I assume. So this has led me to wonder if this virus has some type of self-preservation protocol built into its programming.

Basically I’ve reached the limit of my knowledge with this and I would like to know if I should just tell him to scrap the hard drive and start from scratch. As stated I will include the logs and zip files once they’re complete. I just need to know if there’s any suggestions as to what I should do from this point on.

follow the guide and attach the log`s http://forum.avast.com/index.php?topic=53253.0

if you have logs from Combofix and Kaspersky i guess he want those also

Here are the logs for aswMBR, OTL, and Malwarebytes.

This is the Kaspersky link on mediafire for the manual disinfection:

Here are the new logs, it appears to be gone to me. However it’s done this before and then came at his computer again so hopefully it’s finally dead.

The computer is working much better now and none of the original symptoms have occurred. Now my question to you is if he wants to continue to download torrent files. How can I go about so that this could be prevented in the future. He uses primarily btjunkie.org and kickasstorrents to download the music. I know nothing is for certain but I’d like to be able to provide him a greater measure of security from now on to prevent this in the future.

To be honest the onlly way to be sure is not to use torrents - or get Avast for a modicum of protection in that area

The log looks good so lets check for orphans now

Looks like it’s all clear. So anyway we can try to prevent this in the future. I know nothing is fool proof but I would like to not have to do this every month or so. My cousin isn’t as computer literate as me so he can’t handle most of this by himself. ;D
I will set his Anti-Virus program to scan the files before download but just wondering if there is more that I can do.

Unfortunately the ball is in his court, but get him to look at the link at the end of my post

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] [purity] [emptytemp] [EMPTYFLASH] [CLEARALLRESTOREPOINTS] [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
[*]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.
