You need to scan with all programs because each program detects different malware.
Make sure that you update each program to get the latest version of their databases before doing a scan.

-> Start Firefox in Safe Mode (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

https://support.mozilla.com/kb/Safe+Mode

Firefox Safe Mode window will open. DON'T SELECT ANY OPTIONS, just click Continue in Safe Mode

-> The problem does not occur in Safe Mode

-> Create a New Profile as a test to check if your current profile is causing the problems. See:

Basic Troubleshooting: Make a New Profile

https://support.mozilla.com/en-US/kb/Basic%20Troubleshooting#w_8-make-a-new-profile

-> If that New Profile works then you can recover your Bookmarks and Passwords from the Old Profile. See this:

Recovering important data from an old profile

https://support.mozilla.com/en-US/kb/Recovering%20important%20data%20from%20an%20old%20profile

Check and tell if its working.

I have tried that before at the Basic Troubleshooting step, but not working too :((((((

Do a clean (re-)install:

-> Download a fresh Firefox copy and save the file to the desktop.

• Firefox 5.0.x: http://www.mozilla.com/en-US/firefox/all.html

-> Uninstall your current Firefox version and Remove the Firefox Program Files folder before installing that copy of the Firefox installer.

• Do not remove personal data if you uninstall the current version.
• It is important to delete the Firefox Program Files folder to Remove all the files and make sure that there are no problems with files that were leftover after Uninstalling.

Check and tell if its working.

@mha007

this will stop and remove netcut and the redirect problem. I have tested this in vmware and I have emailed the guy who makes netcut and also posted this on cnet downloads.

no antivurs or malware program will pick it up i think it down to the activepacket.dll

this guy mentions the problem http://www.allmoreinfo.com/wow-netcut-defender-2-1-2-with-new-feature.html at the bottom

The page is not redirecting properly

http://kb.mozillazine.org/The_page_is_not_redirecting_properly

Check and tell if its working.

If using the scanners that I listed above does not fix it or if you are blocked from installing those scanners then ask advice on one of the forums that specialize in malware removal mentioned in the Popups_not_blocked article.

• "Spyware on Windows": http://kb.mozillazine.org/Popups_not_blocked

activepacket.dll could not removed(from safe mode too), and the Anti-Virus and Anti-Spam programs can't catch it :((((

have you unistalled netcut do that first

rename activepacket.dll then you can delete it.(might have to reboot first)

or you deregister it

Thttp://www.ehow.com/how_5027161_remove-dll-files-still-running.html

renaming activepacket.dll causing a problem with LAN connection and I can't access Internet anyway. I think this dll file is not related to the problem.
