How to undo the recent Firefox update? McAfee Antivirus Plus antivirus Protection is no longer compatible.

A newer version of Firefox has been improved on my laptop. After the upgrade, a message came that my McAfee Antivirus Plus would be more compatible with the new version of your product.

Again, I have several months in use more protection against viruses and do not have the money to buy something else. I need antivirus protection work and need detailed instructions on how to return to the old version of Firefox 4.

If you can't help me, I have to go to IE and I really want to do.

I have a fairly new laptop bought in October 2010 and am under Windows 7 operating system.

Thank you.

RESPONSE! Go to your downloads folder and find your old installation of Firefox 4 icon. CLICK on IT and reinstall! It replaces your recent update and return to Firefox 4! WOOT WOOT!
