Brief expert summary and next steps tied to the thread

The AVG alert pointing at C:\System Volume Information_restore and the repeating detections are classic signs of an infection that landed inside System Restore checkpoints; those files are protected by Windows and often show up as “not removable” to normal AV scans. Good moves already in-thread: ’s suggestions to run targeted cleanup tools and to clear restore points, and ’s reminder to try additional removal scanners. The later manual registry change by (converting the DSO keys to DWORD=3) lines up with known Spybot/DSO fixes but also underlines the need for cautious registry edits.

Why the System Volume Information hit keeps resurfacing — and the safest fix
System Restore stores snapshots in the protected System Volume Information folder; antivirus tools frequently detect items there but cannot modify those archived restore files while System Restore is enabled. To truly remove anything in a restore snapshot the usual, documented approach is to disable System Restore (which clears all restore points), reboot, run full up-to-date scans/cleaners, then re-enable System Restore once the system is clean. (support.microsoft.com)

Two urgent things visible in the HJT log

  1. HKCU\Run entry that runs regsvr32 (the “uninstal” regsvr32…image.dll line) is suspicious because regsvr32 is a legitimate Windows tool that attackers can abuse to load/unload DLL/OCX code (a known “Squiblydoo/Regsvr32” abuse pattern). Treat that run key as malicious unless it’s from a known program. (learn.microsoft.com)
  2. The O17 NameServer entries (the numeric IPs) are exactly the kind of change malware uses to hijack DNS resolution; those should be reset to the ISP/router defaults or to known-good DNS servers and the DNS cache flushed. Also check the hosts file. (bleepingcomputer.com)

Practical cautions and useful tools
Always export/back up any registry key before changing it (or make a full registry backup) and document any manual edits so they can be reversed. After clearing restore points and removing suspicious run/BHO entries, run a layered cleanup: an up-to-date AV + on‑demand scanners (Microsoft Safety Scanner or Defender Offline) and a dedicated anti‑malware tool (Malwarebytes) to catch PUPs/rootkits. Re-enable System Restore only after multiple clean scans show no active infection. (support.microsoft.com)

Notes: removing infected restore points clears the repeating AVG popups; editing the registry fixed the Spybot DSO flags in this thread, but always back up first and prefer offline/boot-time scans for persistent infections.

Download CWShredder from & run it. Select the fix button & it will get rid of everything related to CoolWebSearch that is stored in it's database. Close ALL windows, including IE, before running CWShredder. Reboot.

To help prevent this from happening again, install the patches for the vulnerabilities that this hijacker exploits by going here for your critical updates.

Reboot after doing this & post another log please.

is it o.k?
i really hope so..
and, i have another problem, sometimes while on the internet i got message saying : "a runtime error happened. do you wish to debug?" - i hit "no" and everything seems ok, but is it?

Member Avatar for crunchie

Do the following first & see if the problem persists.

Close all (browser) windows & rescan with hijackthis. When the scan is finished place a check in the box to the left of the following entries & click 'fix checked' :

R3 - Default URLSearchHook is missing

O2 - BHO: (no name) - {A9A674BF-771F-42E5-A440-D20DDA85A862} - (no file)

O4 - HKCU\..\Run: [uninstal] regsvr32 /u /s image.dll

Reboot.

Clear your restore points now like so..
Turn off System Restore.
On the Desktop, right-click My Computer.
Click Properties.
Click the System Restore tab.
Check Turn off System Restore.
Click Apply, and then click OK.
Reboot.
Turn ON System Restore.
On the Desktop, right-click My Computer.
Click Properties.
Click the System Restore tab.
UN-Check *Turn off System Restore*.
Click Apply, and then click OK.

Update AVG & rescan your system. Note that all previous restore points will be lost.

hi!
the "small problem" ->that little message-box saying: "a runtime error has occurred. do you wish to debug?" ->is growing rapidly..... now i can't even use my mailbox on the hotmail, cause everytime i open that page , those "runtime errors" keep showering on me.... situation with other websites is not so bad, here i got that message every ten minutes or so, amazon.com is ok for me (by now) , microsoft.com, where i tried to download updates , is horror.....errors all the time....
please, try to help me..

Member Avatar for crunchie

Did you follow instructions from my last post?

Open Internet Explorer - click Tools - Internet Options - Advanced. Make sure Disable script debugging is ticked and Display a notification about every script error is unticked then Apply and OK your way out

Member Avatar for marijana

yes, i followed all your instructions, thanks!
now i dit that last thing: dissabled script debugging, the other one, "Display a notification about every script error " was unticked allready...
i'm gonna give it a try now :-)

Member Avatar for marijana

:-)
disabling script debugging solved that problem all right! THANKS!!!!
but i still have some other stuff....
every time i run Spybot-S&D it finds this:
--------------------------------------------------------------------------

i hit "FIX" button, it said that it's fixed, but than i run Spybot again, and the same five problems appear.....
i did all that while i was disconnected from the internet.....
and it will go on as many times as i run Spybot....
what does it mean?
btw, Ad-aware finds no prob, nor does AVG-antivirus...
so, PLEASE HELP AGAIN :-)

Member Avatar for crunchie

The spybot forums would be the place to look for help regarding the DSO exploit. There seems to be a problem with spybot & there would be a fix at there forums, I am sure. You may be able to set spybot to ignore it on the scans.

I had several similar troubles this past week and got bit by Korgo, Sasser, Blaster ans Backdoor.Nibu! My AV program found some of them but not the newer ones (Korgo, latest Sasser version). I dowloaded a utility from Network Associates called stinger that identified and killed them. Its free and very effective for what it is written for, which is the latest 30 or so bugs. I also got some messages that were similar to what you have.

Here's the URL;

Member Avatar for marijana

me, again, just to tell you how i got rid of that DSO EXPLOIT !
i just changed those five values in the registry that Spybot reported NOT EQUAL to 3.
changed them to EQUAL TO 3.
Spybot reported the full path, so it was easy to find them. They weren't "DWORD" values, but "SZ" values, (as if i know what that means), so i first killed those "SZ"-s, and created new "DWORD"-s, set their values to 3,
and that was all!!!!
