Hey,
Yesterday I found out, after downloading and installing a torrent file (bsplayer pro+keygen for it) that it was infected with a trojan. I also keep getting annoying pop ups with IE (I never use IE myself, only firefox).
I'm running Windows XP, SP2 and I use AVG as antivirus program. I have scanned my computer with AVG and it picked 4 trojans into quarantine, also I've scanned my whole computer with it several times afterwards and it doesn't find anything else.
I also have spybot seek & destroy and ad-aware and I've scanned my system with those several times. Everytime ad-aware finds around 10-20 tracking cookies, I always remove them, but they come back again and again.
When I ran spybot's scan, it always finds one file (Smitfraud-C.CoreService) and sometimes some other cookies as well. The file is named "core.cache.dsk" and it's in my WINDOWS\system32\drivers folder. I click to fix the problem, spybot said it's fixed and pops up this notification about registry entry change. It says "Entry: SpybotDeletingB4851" and New data: command /c del "C:\WINDOWS\system32.drivers\core.cache.dsk".. I click allow change as I'm guessing that it's trying to delete the file. It pops up few more of same kinda notifications with same information, AND sometimes one notification that says "Entry: LogiSPSetupNeedReboot", I can't remember right now what it says on the old data part. I clicked deny change on that as I didn't know what it was.
I've deleted everything from my Local Settings\Temp folder as well as from my other temp folders. And of course I've deleted the torrent and uninstalled BSPlayer and so on. I've checked my add/remove programs and there doesn't seem to be anything dodgy.
I googled the core.cache.dsk and found some other people having same problem, though some of them also have a file called core.sys in their system32\drivers folder, I do not have that. I've also tried to delete the core.cache.dsk file but it just says access denied. I checked with wholockme and it says Locker Name: System .. And when I try to kill the process, it says 'Access to this Process is denied.' :S

Thank you in advance for the help.

EDIT: I just restarted my computer in safe mode and tried to see if I could delete the core.cache.dsk file but couldn't find it. After I restarted back in normal mode, I got about 10 notifications that my system has recovered from serious error plus about 10 of those spybot's notifications about registry entry change (the same ones about the core.cache.dsk) and two notifications about KernelFaultCheck (and as I'm guessing that's got something to do with the 'system recovered from serious error' notification, I clicked allow on it)

Hi Deleng,

Yes it can be difficult to remove, we will use a special tool to do the job.


Temporarily disable Spybot's TeaTimer. This is a two step process.
First:
  • Right click Spybot in the System Tray (looks like a calendar with a padlock symbol)
  • Choose Exit Spybot S&D Resident
Second:
  • Open Spybot S&D
  • Click Mode, check Advanced Mode
  • Go To Left Panel, Click Tools, then also in left panel, click Resident
  • If your firewall raises a question, say OK
  • Uncheck the box labeled Resident TeaTimer and OK any prompts.
  • Use File, Exit to terminate Spybot.
  • Reboot your machine for the changes to take effect.

Then download ComboFix to your desktop
  • Double click combofix.exe and follow the prompts
  • Note: Do not click ComboFix's window while it's running - it may cause it to stall!
  • If after ComboFix finishes you do not have internet access, then reboot your computer to restore it
  • When finished, it shall produce a log for you, please post it in your next response

Now open HijackThis, select Open the Misc Tools section
Press the Open Uninstall Manager... button, then press Save list...
Save the Uninstall log to your Desktop and include a copy in your next response.
Now press Back and Scan and then Save log to create and save a new HijackThis log.


Once complete, please post the ComboFix report, the uninstall list and a new HijackThis log.
