Cant find/remove virus
« on: December 27, 2003, 03:40:04 AM »
I first noticed I had a problem when I turned on my computer and it took 5 minutes to get to windows. Then I notice next to my mouse pointer, a blinking cd icon is flashing all the time. Internet explorer takes about 5 minutes to open the first time. I installed Avast and it found bugbear-b and win32:trojan-gen. I removed them but bugbear keeps coming back. In my msconfig under startup, there is a item called "ivbxxbi" I have unchecked it but it turns it self back on every time I check. This ivbxxbi is also in my local/settings/temp folder. I cannot delete it and it shows as not infected. I dont know whats what to do, the system is way too slow to use and probably not secure. Im beginning to think I must format but maybe you guy know whats wrong.

I removed them but bugbear keeps coming back. In my msconfig under startup, there is a item called "ivbxxbi"

It is an Afcore Variant, i d o not know why Avast did not find it, because they have a sample of this Malware. Maybe it is not ITW, but it is definitly not ZOO. You can easily remove it by typing:
rundll32 C:\WINDOWS\System32\ivbxxbi.dll,uninstall in a Dosbox. Than disable the Startups via msconfig or Hijackthis and make a restart.
Use the Avast cleaner http://www.avast.com/i_idt_171.html to get rid of the Bugbear Worm. Where does Avast report the Bugbear(file/folder)?

When I type that it gives me a error saying missing entry: uninstall. The bugbear was in system restore files, which I turned off, and if I remember it was iexlporer once, audio.exe, pagefile.sys and others.

Da*n, okay an other try, are you able to find the file in the System32 folder? If yes, than start a dosbox change to the system32 folder, open the Taskmanager and kill the Explorer.exe(!!) Task and all rundll32.exe Tasks, than  delete the file, by typing: del ivbxxbi.dll
  and restart.

Raman, before I read this I created a win98 boot disk to get to dos (I use xp but fat32). I deleted the ivbxxbi.dll file through dos sucessfully because it gave me errors saying it could not find it on startup. So that is gone, but I still get this strange flashing cd icon next to my mouse pointer, its like the hourglass but it blinks all the time. Also my computer took just as long to turn on, but internet exlporer opened at a decent speed. Im gonna do another scan at the moment.

FAT32, nice to here that, because that thing  hide itself in alternate datastreams of NTFS drives and is difficult to find. One thing you should really do is to update your Windows /IE via www.windowsupdate.com.

Hi all, I am working on a problem and need some help...a lot of help  :)  It is related to pagefile.sys.  I ran BART and it reported an infection, ZLOB, with the infected file pagefile.sys.  BART removed it from the directory, said it was deleted so I thought I was home free.  However, when Windows booted and re-built pagefile.sys it placed pagefile.sys back in the same area on disk, so I had to use the shreader option BART provides.  That seemed to work.  AT least until I rebooted Windows and then later ran BART again.  ZLOB was back.  I repeated the process and found that other infections would come up, also attached to pagefile.sys, such as Agent, BV, and a few others.  I have ran AVAST's own AV, as well as Trend-Micro, Norton, AVG, and quite a few others.  In all cases they report no infection so take no action.  But when i run BART again it reports the infection.  I think thats because they may not be able to scan pagefile.sys as it is in use, and a Windows Protected File.  I have tried turning System Restore off, turning pageing off, and a few other things.  I have not tried a 5 pound sledge yet..but it may come to that :).  I also tried moving the pagefile to another disk, but that was unsuccessful as well.  I have searched all over for information and have yet to find much.    I am somewhat convinced that the real culpret is somehow imbeded in Windows XP Pro, and when Windows sets up pagefile.sys at boot time...whammo!   As to why no AV software finds it is beyond me.   My question is has anyone else experienced similar problems and if so, did you get rid of this pest.

Thanks
Mike Nelson

Hi mnelson,

Why have you attached this question to a very old topic?

In future, please start a new thread in the appropriate board.

Zlob is a Trojan downloader associated with rogue anti-spyware scams.

To look for Trojans, I recommend the anti-Trojan program Ewido (requires win200/XP):

http://www.ewido.net/en/

The malware downloaded by Zlob is very tricky to remove but there is a removal tool:

Follow the instructions on the page.

Good luck!
