Recently , within the space of a week, I have worked on 3 dell PC’s running Windows Vista which have all suddenly lost their internet access. On closer inspection it turned out that these machines had serious network issues ranging from being unable to ping their default gateway or worse still they could not get an IP address from their ADSL/Router.
The common thread between these machines was Vista and McaFee and the fix was to uninstall and reinstall McAfee on these machines.
ON further inspection it turns out McAfee have identified this issue and that the buggy update applies to all McAfee users not just Vista.
“McAfee has identified an issue with DAT 6807 and 6808. Specifically, these DATs can affect McShield.exe and may cause issues with the On-Access Scanner,” it stated.
