Hi

The file beep.sys in windows\system32\drivers keeps on being infected. I have deleted it and even copied a clean one but about every 10 seconds it is back with the infected one. I have also replaced the null.sys with a clean one. Together with this is a pop up that ask me to insert your windows xp home cd.

I have scanned the pc with, malwarebytes, spybot, superantispyware, avira and avg and I did remove a lot of spyware and malware.

I can't figure out where this infected file keeps on coming from.

Any ideas will be grately appreciated.

Regards

I tried sdfix as well. Everything seems to see beep.sys has a problem but after the fix it still is infected. Even if you delete the file after a few seconds it is back and once again infected.

Don't know what else to try.

Now that you were successful in creating a Root Repeal log you need to post it in our HJT forum There they will help you with the removal through some custom scripts and programs that we cannot run here in this forum

First, try to run a DDS / HJT log as outlined in our preparation guide:
http://www.bleepingcomputer.com/forums/t/34773/preparation-guide-for-use-before-using-malware-removal-tools-and-requesting-help/

If it won't run, don't worry, just give a brief description and tell them that this log was all you could get to run successfully

Post them here:
http://www.bleepingcomputer.com/forums/f/22/virus-trojan-spyware-and-malware-removal-logs/

The HJT team is extremely busy, so be patient and good luck
