Unable to remove the trojan TR/Dldr.WinShow.AX
 

I am unable to find or remove the trojan TR/Dldr.WinShow.AX. It is being detected by AntiVir as TR/Dldr.WinShow.AX and by Norton as MHTMLRedir.Exploit. The virus is inserting itself into the windows temp file. Once I direct my virus programs to delete the virus, it reinserts itself into the same windows temp file under a slightly different name each time. For example, AntiVir is currently reporting that C:\WINDOWS\TEMP\TMP182.TMP is the Trojan horse TR/Dldr.WinShow.AX. If I tell AntiVir to delete the file it will reappear immediately as TMP183.TMP. Occasionally other directories will be simultaneously infected with the virus under different names as well. I found generic manual removal instructions for winshow in several forums on the net and I have searched my system and reg using those instructions. I did find winshow and winlink in the reg by performing a search within the reg, but I did not find any malicious files or entries in the folders in which the directions said to look. Once I deleted the file I found with the reg search tool my virus programs still report the virus. I cannot find any information for this specific virus on the net. I have found removal instructions for many of the winshow variants, but not the one I have. I'm not even sure that matters, but none of the directions I have followed have worked. If it helps, my HijackThis log file reads as follows:

AntiVir, Norton, Spyware Blaster, Adaware SE, Spyware Doctor, SpyBot SD, Bazooka, and CW Shredder all failed to remove this virus. I would appreciate any help you may be able to offer.

Thanks :eek:

Clear out your Temporary internet files and other temp files.
Go to Start > Settings > Control Panel >Internet Options.
Under the General tab click the Delete temporary internet files,
delete all Offline content as well. Clear out Cookies.

Also, go to Start > Find/search > Files or folders > in the named box, type: *.tmp and choose Edit > select all -> File > delete.

Empty/delete the entire contents of the C:\Windows\temp folder and C:\temp folder, if you have one. (Contents but not the folder itself.)

C:\Documents and Settings\username\Local Settings\Temp\

In order to view these files you may have to select 'show hidden files/folders.' Instructions on how to here.

Empty the Recycle Bin.

Run your AV again.

Thanks for the help :) . I followed all of you directions, but the virus is still present and behaving in the same irritating manner. If you have any other suggestions, I will gladly try them too. I am contemplating the 12 gauge solution :eek: ...lol.

Thanks,
Colonel Fox

Microsoft has released a patch MS04-013 to address this issue.
Check to see if you have it downloaded already. There is nothing to remove from your PC as this is an exploit.
