Hi folks,

I found this forum after Googling for help with my vundo problem, and I hope someone can please give me a hand with this.

A few days ago my system became infected with something that was causing lots of ads and pop-ups to open, and the system slowed down to a crawl. I use McAfee as my general antivirus software, but it didn't detect anything when the infection happened. I tried scanning with it after the symptoms appeared, and it still didn't find anything. I then scanned with AdAware, which identified vundo.gen.i. I performed a removal through AdAware, rebooted, and scanned again, and the malware was still there. I've since downloaded VundoFix, as well as Malwarebytes AntiMalware, and run them. They seem to have gotten rid of the vundo, and my system appears fine now, except that my web browsers are still running extremely slowly, almost to the point of freezing. My usual browser is Firefox 3.0.5, but I've also tried the newest version of IE, and both have the problem, even after clearing all cookies, cache, etc, and rebooting. I've even tried uninstalling and reinstalling Firefox, but that didn't help. My operating system is Windows XP Professional. I suspect that something is lingering from the malware that is causing these problems and very much would appreciate help in fixing this.

Please let me know any additional information or files I need to provide, and I'll do so as quickly as possible. This issue is really driving me crazy.

Thanks in advance,
-Jason

Hi Mark, and thanks so much for the reply. Earlier this morning I downloaded and ran SuperAntiSpyware Free Edition, and it identified and apparently removed 9 infected files / registry entries / somesuch. Since then, things *seem* to be running better, but I'm very cautious about it, because I know how pervasive these things can be. I just finished running MBAM again at your recommendation after updating it. It found no malicious items on this scan, and here's the log:

Malwarebytes' Anti-Malware 1.32
Database version: 1648
Windows 5.1.2600 Service Pack 2

Memory Processes Infected: 0
Memory Modules Infected: 0
Registry Keys Infected: 0
Registry Values Infected: 0
Registry Data Items Infected: 0

So I'm cautiously optimistic, but is there anything else I should do just to make 100% sure this thing is gone?

Thanks again,
-Jason

Let's see the SAS log too
Try this scan to double-check
--------------------------------------

Please download Dr.Web CureIt & save it to your desktop. DO NOT perform a scan yet.

Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with Dr.Web CureIt as follows:
  • Double-click on launch.exe to open the program and click Start. (There is no need to update if you just downloaded the most current version
  • Read the Virus check by DrWeb scanner prompt and click Ok where asked to Start scan now? Allow the setup.exe to load if asked by any of your security programs.
  • The Express scan will automatically begin.
    (This is a short scan of files currently running in memory, boot sectors, and targeted folders).
  • If prompted to dowload the Full version Free Trial, ignore and click the X to close the window.
  • If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All.
  • When complete, click Select All, then choose Cure > Move incurable.
    (This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
  • Now put a check next to Complete scan to scan all local disks and removable media.
  • In the top menu, click Settings > Change settings, and UNcheck "Heuristic analysis" under the "Scanning" tab, then click Ok.
  • Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
  • When the scan is complete, a message will be displayed at the bottom indicating if any viruses were found.
  • Click "Yes to all" if asked to cure or move the file(s) and select "Move incurable".
  • In the top menu, click file and choose save report list.
  • Save the DrWeb.csv report to your desktop.
  • Exit Dr.Web Cureit when done.
  • Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
  • After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)

Hi again,

Here's the log from the SAS scan I did after my initial post:

Hi Mark,
It ended up taking most of the night to run the check, so I just let it run overnight. It looks like it found a couple of files, one in my Movies game installation and one elsewhere. Here are the results from CureIt:

Movies.exe;C:\Program Files\Lionhead Studios Ltd\The Movies;Win95.SK;Incurable.Moved.;
A0179380.exe;C:\System Volume Information\_restore{A848A17C-32CA-4002-95B3-ED6F7E256268}\RP1076;Win95.SK;Incurable.Moved.;

It looks like my prior success was premature, as Firefox is slow again. It seems like the longer I use the browser, the slower it gets until I reboot.

-Jason

If it's still slow, I'm going to suggest that you follow the instructions and prepare a HJT log, here:
http://www.bleepingcomputer.com/forums/t/34773/preparation-guide-for-use-before-using-malware-removal-tools-and-requesting-help/
Then post the log in the proper form here:

Our team members are rather busy, so it may take a while to get to you
Be patient and good luck

Hi Mark,

Today it seems to be running a lot better, so I'm hoping that my problems might be taken care of now somehow. If I do see the symptoms showing up again, though, I'll do the HJT log and post it there. Thanks so much for all your help with this.

-Jason
