First I would like to thank you for taking the time to help me.

I am trying to clean a friend's laptop that was severely infected. I believe that I removed all of the malware except for the bidisp.dll file. It continues to appear after scans by AVG, MBAM, HiJack this, Combofix, etc., etc., etc. I do not know where he got the viruses but I do know that his antivirus software was woefully inadequate. I installed AVG with all the updates but still cannot get rid of this problem. Your help is greatly appreciated.


PS I hope I am correctly submitting this information. It is all new to me. Thanks again...

Hi HeWolff,

Please open this page in your browser:

Fill in the link to topic field with a link to this topic
Copy/paste the following into the Browse to the file you want to submit field:
Then press Send File, this will upload the file for analysis


Download RSIT by random/random to your Desktop (right-click the link, select Save Target As..., select your Desktop and press Save)

  • Double click RSIT.exe to start the program, and click Continue at the disclaimer screen.
  • When the scan is complete, two text files will open - log.txt <- this one will be maximized and info.txt <-this one will be minimized
  • Make sure Format->Word Wrap is unchecked
  • Copy (Ctrl+A then Ctrl+C) and paste (Ctrl+V) the contents of log.txt and info.txt in your reply


Once complete, please post both RSIT logs, you won't need to produce a new HijackThis log as RSIT produces one for you.
