OK so I had the same problem after McAfee added new updates. Was stumped. Contacted McAfee and was told to reinstall. Did this and it worked fine until the updates were added. Back to square one.
Got this info from my brother-in-law and it works!!!!!!:
Turn on McAfee Firewall
Click on Firewall and then on Settings
Click Ports And System Services
Make sure Web Server Port 80 is clicked.
And that's it!
Will sort it out for you. Somehow McAfee updates unclick this.
Hope it helps!
I had the same problem.
Almost no more internet connections since 8 days (google chrome, firefox, ie) but mail was ok along with some vpn connections.
Without firewall, everything is fine (except that there is no more security while browsing)
With the firefall, no internet connections (or almost none as explained by other people above)
I did the trick explained above by molly133 and it did it for 30 minutes.
I just had to activate/desactivate/activate again the firewall after the modifications so that they are taken into account
then, after these 30 minutes, internet connections are blocked again! But all the Ports settings are identical to 30 minutes before.
As other people, i didn't do any special things on my PC (vista), only automatic updates from windows, mcafee, java, etc.
It's the first time i have such awfull trouble with mcafee!
So, McAfee Crew, we are a lot of people needing your help!
i got this (see image, text is in french)
it means that the server takes too long to answer (there it is yahoo but it's the same with almost any other server)
if i disable the firewall, it works... but i hate surfing without firewall ;-)
i'm using Mc Afee Internet Security (information from about mcafee)
mcafee security center
last update september 28, 2011
mcafee virus scan
last update october 7, 2011
mcafee personal firewall
last update for the firewall done the septembre 21, 2011
i didn't find any build number
all the updates are automatic
there is no message related to mcafee... but when firewall is disable it always works.
When the firewall is up, then it depends.
Since my last message, after checking some checkboxes (port 80, etc) as suggested by molly133, then the network access works far better.
But from time to time, connexions take too long again and i need to wait between 5 minutes and one hour to have access again.
I have also seen that when a scan is running, sometimes (not always) the network connexions are bad or simply not working.
From another computer, on the same local network (behind the same rooter) , without mcafee, everything is ok.
It is not a conflict between computer as i have this problem when my PC is the only one powered.
I'm using mcafee fro more than one year and the problem started around a week ago but i just realize it came from mcafee today
I'm running the Virtual Technician. I hope it will find something.
The firewall behaviour is really strange and quite boring.
I will let you know what's happening.
thanks for the link anyway.
2 problems found:
- 1 registrey key was not correct. fixed by the VT
- 1 DAT out of date. Impossible to fix with the VT so far...
I will launch it again later after manually updating mcafee
- the DAT problem has deasappeared now.
Stil, browsing remains troublesome...
