Stupidly I opened an un-scanned exe from a torrent yesterday. Now I got some weirdness. What do I do next? My tech level is high.

Symptoms:

--It broke Firefox - when I try to run it, nothing happens in taskmanager. I got it working again by renaming firefox.exe to firefox1.exe

--in IE, my google searches results are sabotaged with ad-links. See screenshot here: http://i26.tinypic.com/9vfmhf.jpg

--my hosts file is fine ( I cannot see any changes beyond default), but somehow I still cannot access many anti-virus domains (including bleepingcomputer.com)

--Ran an AVAST boot-time scan....the only thing found was Win32:VarDrop in system32\clbdll.dll. I did not remove it yet. should I?

--I notice some suspicious dll's in the system32 directory, when I sort by date you see some suspicious dlls. See screenshot here: http://i30.tinypic.com/2s6liiq.jpg


Help? What next?

Thanks for your time!!

Pete

Update: I was able to get rid of the 5 trojan dll's which appeared in my system32 dir, and also cbldll.dll.

AVG now only detects one possible issue: ntoskrnl has changed. All it lists is a previous size and a new size (in kB). It cannot be repaired by AVG or Avast as far as I can tell.

Is the change to the kernel (WinXP SP2) a sign of an infection? Please someone help me out here?

Should I run some other program like Spybot and post the log in that appropriate sub-forum?

My IE searches are still redirected. I still cannot access many AV domains like AVG or bleepingcomputer.com...

Sigh - I could use some help here.

Should I just go post a hijackthis log? Should I go to another forum?

Hello petekw and welcome to BC :thumbsup:

My apologies about not receiving a response. We are all volunteers here and sometimes things slip past us. I see that you have since posted a new topic in the HiJack This forum here: http://www.bleepingcomputer.com/forums/t/156506/domain-blocking-ie-search-redirect-disable-firefox/ I must alert you that we have a huge backlog of logs there. Some folks have waited up to a month to get a response. If you prefer to receive assistance here, please send me Private Message and I will reopen this topic, delete the HJT topic, and contact someone to assist you here.

Otherwise, because you have the aforementioned log posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a HJT Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the HJT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

If after 5 days you still have received no response, then post a link to your HJT log in the thread titled "Haven't Had A Reply In Five Days?".

To avoid confusion, I am closing this topic. Good luck with your log.

Orange Blossom :flowers:
Help us help you. If HelpBot replies, you MUST follow step 1 in its reply so we know you need help.
