DNS problems
Hi All 
I Hope someone will be able to help with a problem I am having with DNS on my home network.
I have 2 windows and 1 Linux machine - the 2 windows machines are having the problems and the Linux machine works fine, this would rule out the router and beyond as the source of the problem.
One windows machine connects to the router via Ethernet the other by wireless. both machines give "server not found" type errors in both Firefox and IE, only very occasionally will a page load, however if i use a resolved name i.e http://216.239.59.104 then the page loads instantly on both machines.
The problem started a few weeks ago and also affects my mail client (outlook) which can be attempting to connect over a period of hours before a successful connection is made.
I've checked things like the "Hosts" file for malicious entries as deep down i have a feeling it possibly a virus that is causing all the problem, although a full system scan picked up nothing.
if anyone knows how to fix this problem or knows of a virus that behaves this way I would be grateful to hear from you.
* I've also tried - flushing DNS cache - deleting all cached Internet pages, cookies etc - changing IP addresses / DNS Servers from static to assigned and back again
Many Thanks,
Steve.

Thanks Phil,
I don't use Zone Alarm I use McAfee total protection 2008, but it sounded like to much of a coincidence not to give it a try. after uninstalling the patch everything was back to normal and working fine
Unfortunately this does leave a security gap until i've figured out a workaround, I'm in the process of updating McAfee but they have no reported issues with the windows patch.
Anyway thanks again Phil
