McAfee Total Protection Firewall blocking all internet Access

I just upgraded to Total Protection from AntiVirus Plus, everything was going good, after I restarted my PC (The last prompt during installation), when I logged onto Windows all internet traffic was blocked. I've tweaked settings on Security Center but I can't figure it out, currently the ONLY way I can manage is by completely turning off the Firewall.

I've tried Restoring Defaults on the Firewall but traffic is still blocked. This never happened before I and I can't figure it out.

Some assistance please anyone ^^;

Re: McAfee Total Protection Firewall blocking all internet Access

Too add a few things, I upgraded from Anti Virus Plus 2010 to Total Protection 2011, I used the disk, it removed Anti Virus Plus 2010 and installed the latest version of Total Protection 2011 including online updates,

I'm using Windos 7 64Bit Home Premium on a custom Built PC.

Again to clarify this issue started when I upgraded to Total Protection, 20minutes ago with Anti Virus Plus I had no issues whatsoever.

Nothing I change on the Firewall EXCEPT turning it off will allow me internet access. Windows Firewall is off, and there's nothing else running besides McAfee.

McAfee Personal Firewall

Version: 12.0

Build: 12.0.335

Last Update: 6/25/2011

Edit: I found this post, my problem looks to be exactly this.

Re: McAfee Total Protection Firewall blocking all internet Access

A simple thought,

  • Run Windows update and install all important and optional updates
  • Restart the computer to safe mode with networking.
  • Restore Firewall settings to default.
  • Turn off Firewall, run McAfee update.
  • Restart the computer to normal mode and turn on Firewall

Let me know the status after the above steps.

My dear Mr/Ms Jayadeep,

I being of sound mind and body...

The first thing you suggested is; Run windows update. 

So I remind you of the subject of this posting:  McAfee Total Protection Firewall blocking all internet Access

I am using a different computer to find a solution for the same exact problem, so now if you can answer the original question...

  • Run Windows update and install all important and optional updates
    • I always do this so this suggestion can be scratched.
  • Restart the computer to safe mode with networking.
    • Same issue
  • Restore Firewall settings to default.
    • I mentioned in the first post I had done this already.
  • Turn off Firewall, run McAfee update.
    • Very first thing I tried.
  • Restart the computer to normal mode and turn on Firewall
    • Tried this also. Did not help, was hoping it would.

I've managed to fix the issue, I ran the Virtual technitian and it found nothing wrong. After trying everything else, I decided to completely uninstall McAfee and re-install it, however this time I didn't allow the Auto-Update when prompted (Infact i disconnected the internet). After the installation was finished, I then updated and the issue was fixed, was really weird as I'll never know what happened and why. I did a lot of googling and found this issue come up a few times. My thought's are either a file corrupted during installation (It was never interrupted in any phase) or something was missed the first time and Virtual Technician didn't detect it.
