Posted 21 July 2008 - 07:03 PM

I've come across a similar problem here - http://www.bleepingcomputer.com/forums/t/120285/avg-anti-virus-found-cwindowssystem32shell32dll-and-cwindowssystem32driversetchosts-changed/. VERY similar. I had this problem a few days ago and a site online mentioned a few potentially infected files that AVG normally finds for the hosts file. I used HijackThis to locate them and get rid of them, and for a few days it worked.

But AVG is still saying the file is infected, and tonight my computer has started denying me access to certain areas again. I have two separate hard drives - C Drive holds Windows, E Drive has all of my media. I'm allowed access to some parts of E and none of C. I can get to control panel if I go through the Start menu, but it's shaky.

I, like the user I've linked to, also had the Sims 2 game installed - is this just a coincidence? My Spybot went insane when this infection was first found, too. I had to remove it because it was causing many problems. AVG also started saying files it had scanned when they were first downloaded were now infected. But it only lists the hosts file as being infected.

I followed the steps advised to the user in the link, and it hasn't worked for me I'm afraid. I'm getting classic Windows error messages, which sometimes mention Dr Watson Debugger. The computer is also freezing up when I try to access my WD External hard drive. It was suggested to me that my E Drive might be bugged because it came from an older computer, but I thought that because it's Windows error messages I keep getting it's more likely to be a problem with C...am I right? It was also fully formatted before being placed into this new computer, so I don't know if it even counts. I'm afraid I'm not very computer knowledgable.

These are my stats:

System: Microsoft Windows XP
Professional
Version 2002
Service Pack 2

Computer:
Intel® Core™2 Quad CPU
Q6600 @2.40GHz
2.40 GHz, 2.00 GB of RAM

Motherboard = MSI P31 Neo
Display = ATI Radeon HD 2400 PRO

AVG Free Anti-Virus

The soundcard is built in to the motherboard but NOT used - I use 5.1 Soundblaster Audigy EAX speakers that run off of their own Creative Audigy card. The computer has complained about this recently after a 'computer has recovered from a serious error' message and continues to nag about the PCI controller even though it's been fully disabled.

If this computer can be rescued by a format, please let me know >.< I only just spent several hundred on this thing and I really, really don't want anything to happen to it. As I mentioned, I tried the HostsXpert method and it's done nothing. Seeing as I have Sims 2 installed like the other user and I know it's caused problems for other people in the past, is it possible that this is a problem for me?

UPDATE: I can now get into one of the folders I wasn't allowed to enter before and access the files, but the error message is still there - it's just letting me use the files whereas it wasn't before. If I try to go to the previous folder the whole window closes down. Still can't get to C Drive though

Hello, manda8825.
:thumbsup: to BleepingComputer.com

My name is Billy O'Neal and I will be helping you. (Billy or Bill is fine, if you like.)
Please give me some time to look over your computer's log(s).
Please take note of the following:
  • In the meantime, please refrain from making any changes to your computer.
  • Also, even if things appear to be running better, there is no guarantee that everything is finished. Please continue to check this forum post in order to ensure we get your system completely clean. We do not want to clean you part-way up, only to have the system re-infect itself. :)
  • If you do not understand any step(s) provided, please do not hesitate to ask before continuing. I would much rather clarify instructions or explain them differently than have something important broken.
  • Finally, please reply using the Posted Image button in the lower left hand corner of your screen.
We need to create a Deckard's System Scanner (DSS) Log
Please download Deckard's System Scanner (DSS) from one of the links below and save to your Desktop.

Primary Mirror
Secondary Mirror

DSS will do the following:
  • Create a new System Restore point in Windows XP and Vista.
  • Clean your Temporary Files, Downloaded Program Files, Internet Cache Files, and empty the Recycle Bin on all drives.
  • Check some important areas of your system and produce a report for an analyst to review.
  • Automatically run HijackThis. It will also install and place a shortcut to HijackThis on your desktop if you do not already have it installed. So if HijackThis is not installed and DSS prompts you to download it, please answer yes.
Note: You must be logged onto an account with administrator privileges when using Deckard's System Scanner.
  • Close all applications and windows.
  • Double-click on dss.exe to run it and follow the prompts.
  • If your anti-virus or firewall complains, please allow this script to run as it is not malicious.
  • When the scan is complete, two text files will open in Notepad:
    • main.txt <-- Will be maximized
    • extra.txt <-- Will be minimized
  • If not, they both can be found in the C:\Deckard\System Scanner folder.
  • Please copy (<Control>+C) and paste (<Control>+V) the contents of main.txt and extra.txt in your next reply.
Note: When running DSS, some firewalls may warn that DSS is trying to access the Internet; especially if you are asked to download the most current version of HijackThis. Please ensure that DSS is given permission to access the internet.
Note: If you get a warning from your anti-virus while DSS is scanning, please allow DSS to continue as the scan is not harmful.
