Hi, Board.

I hope someone here can help me because I am nearing my wits end!

First thing's first, I am running Windows XP Professional SP3.

Something happened this past weekend and I don't know what. It started with Firefox just crashing for no particular reason. Further testing revealed that IE would also crash. I also found that trying to run cmd or regedit caused explorer to restart. Another symptom is when I browse I sometimes get random redirects to other sites. But this does not happen all the time. I checked my hosts file and it seems fine. These symptoms appear to be familiar, I've seen a lot of posts about them but I have yet to find something that will help me out. I want to also mention that something similar happened to my PC last year, in December, but I managed to cure that problem. Or so I thought.

So what software have I tried using so far?
1. I use AVG Antivirus. I recently updated to the newest version, 8.5. This installed just fine but it cannot connect to the net for updates, it always fails. But I am able to download the updates manually and then update from directory. But it's still weird how AVG cannot connect.
2. StopZilla.
3. LavaSoft Ad Aware
4. Malwarebytes Anti-Malware
5. www.bitdefender.com online scan
6. onecare.live.com online scan
7. sfc /scannow (but when it asks for my Windows XP SP3 CD, I keep getting messages saying it's the wrong disk. I've tried various things like copying I386 to a local disc and updating the registry but no dice. I said above that I cannot run cmd or regedit but I CAN run command and then run regedit from that window).

So I've tried a few things and in most cases the programs find something, fix it but my computer is still in the same state as before i.e., buggered.

I downloaded HijackThis and generated a report already which I can share if necessary. I tried to install ComboFix but every file I downloaded had a size of 0 bytes and I also can't delete the files because they are being locked by some process.

What else? Hmmmm. I don't know. Hopefully someone can ask me the right questions and I can get you the answers. I am dumbfounded. There is quite obviously something wrong with my PC but none of the software I have can tell me what it is. All my software is uptodate.

Another thing that just happened this evening. Now when I scroll my browser window it's very jerky. It used to be smooth.

Any ideas?

Thanks in advance.


Cheers, Max

Add one more tool to the list. I just ran Trend Micro RootKit Buster with these results:

+----------------------------------------------------
| Trend Micro RootkitBuster
| Module version: 2.52.0.1013
+----------------------------------------------------


--== Dump Hidden MBR and Hidden File on C:\ ==--
No hidden files found.

--== Dump Hidden Registry Value on HKLM ==--
No hidden registry entries found.


--== Dump Hidden Process ==--
No hidden processes found.

--== Dump Hidden Driver ==--
No hidden drivers found.

I will update and then run Malwarebytes again overnight to see what it comes up with.

I would try to use the Windows System Restore program to restore your computer to a few days before this problem started and I would also scan with SuperAntiSpyware

Combofix logs, like HJT logs, are not meant to be posted in this forum

Combofix should not be run unless asked for and under supervision of a HJT team member

Should something go wrong and damages your computer while using Combofix, you are on your own

I didn't post any ComboFix logs, I just said that I was unable to install it. (I did read the forum guidelines before posting). I appreciate the dangers of running these tools and I accept all responsibility should something break. Believe me, it's not my intent to try and fix this on my own. ;) Just looking for some pointers.

Cheers, Max

C:\WINDOWS\Radeon Omega Drivers v3.8.330 Uninstall.exe (Trojan.Agent) -> Quarantined and deleted successfully.


You might try reinstalling your video driver. It could have possibly become damaged

-------------------------------

Please download Dr.Web CureIt, the free version & 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)

Sorry, didn't mean to give you a false positive. No, my machine is still all screwed up but at least my video driver is fixed.

I've been periodically updating and running Malwarebyte Anti Malware and SAS but they are not finding anything. At this stage I am preparing to re-install Windows XP because I've been reading things and now I don't know if my machine can be trusted i.e., can I get it completely clean, can I trust it?

I'm all set now thanks. I deleted my C: partition and re-installed Windows XP. Now starts the wonderful process of re-installing EVERYTHING else. LOL. At least I'm safe and my computer feels better. I'm really surprised that all the software that I tried couldn't fix the problem but all's well that ends well.

Thanks for your help, Mark.
