Whenever I open firefox or go to a new webpage Avast spams me saying it detected a trojan. I opened up the virus vault and see that it blocked prefs.js, prefs-1.js, and elemhide-1.js and it all originated from 5d1c9gc7.default. elementhide-1.js was from 5d1c9gc7.default/adblockplus.

Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.

You can try these free programs to scan for malware, which work with your existing antivirus software:

Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one.
