Sorry -- Windows 7 64-bit.
Now, at least, the Security Center homepage and firewall settings page are consistent with one another --both say my firewall is off!
Try this first....run the McAfee Virtual Technician to see if it can repair the installation. http://mvt.mcafee.com
The infection may have corrupted your McAfee installation and as you seem to have run a whole bunch of tools and found nothing I would uninstall McAfee - Control Panel > Programs > Uninstall a Program
Run the MCPR cleanup tool found under Useful Links at the top of this page. Reboot.
Reinstall from your online account.
Uninstalling McAfee will activate Windows Firewall so you will have some protection whilst this is being done, just don't surf anywhere that isn't necessary.
Hopefully that will reactivate everything.
please, you definetely should get in touch with tech support by phone. They should be able to deal with this FW issue, caused by that infection.
McAfee has already recongnized this one and has a protocol procedure to deal with it.
You can find contact numbers in here: http://service.mcafee.com/
This infection affects the Windows Firewall service, thus affecting the McAfee one.
Get in touch and they should fix it.
Thanks, Alex -- you're absolutely right. I tried Peter's suggestions but they didn't work (thanks for trying to help, Peter!), so I did a little more Google research and discovered tthe relationship between Windows and McAfee Firewalls (how does that work,anyway?).
Basically, a couple of registry entries dealing with Windows Firewall were deleted by the trojan, and that caused the problems with McAfee Firewall. I found the procedure for how to restore the entries here:
Followed the entries by a guy named Balon -- McAfee Firewall came on and STAYED on -- still scanning clear -- everything SEEMS to be OK at this point.
Im glad it worked ok.
Anyway, be careful when dealing with the Win Registry and downloading reg entries and keys from an unknown/untrusted source.
That's an interesting way of fixing McAfee, by fixing Windows F/W. SevenForums is a great place for Win 7 help. Good luck.
