Anti Virus Plus and Internet Disconnection when opening browser after Sleep mode


Has anyone else been experiencing this issue?  From the day of the upgrade of McAfee Anti Virus Plus to the current version (SecurityCentre 10.5.221 update 9/1/11)  my system has been disconnecting from the internet approximately one minute after first opening a new browser session after coming out of sleep mode.  This occurs with both Internet Explorer 8 and Firefox 3. I can sometimes click through three or four pages before it disconnects. I resolve the issue by running Windows Network Diagnostics each time and resetting the Local Area Connection network adapter. Once restored, the internet session runs fine until the next sleep session for the computer. I have run McAfee Virtual Technician which has not fixed the problem. I was also experiencing the problem of the Real Time Scanning not staying on but note that this has now been fixed.

It is a HP Pavillion running Vista and a D-Link DI series modem. I have experienced this problem once before when my McAfee subscription expired and I tried to remove McAfee Anti Virus software. I thought it may have been due to an incomplete removal although also tried using the McAfee removal tool at the time without having an impact on it. I only was able to resolve the issue by renewing my subscription to the McAfee product. A second HP laptop running Windows XP has also been having connection dropouts since the Anti Virus Plus upgrade but at this stage I cannot determine the pattern of dropouts on that computer.

The computer should now detect Internet connectivity after it comes from sleep mode. Please let us know if you still have any issues, connecting to internet after the above step.
