Troubles with McAfee AV

by Nikola Strahija on September 8th, 2004 Some of you might be experiencing serious problems with antivirus software form McAfee these days. It seems that the latest virus definition update from McAfee causes this package to be wrongly identified as a Trojan horse code.

This only happens to users running the latest update of McAfee's AV software. As
a result, ISPWizard is being deleted users' systems. This means that many people are unable to connect to their ISPs because the software that they need has been automatically deleted by McAfee.

Although this problem first occurred as early as 1 September, McAfee hasnít issued any patches jet, and ISPWizard Developer Mark Griffiths, who first reported the problem to McAfee, commented their response: "This is causing major problems for my business, the businesses of my customers [ISPs] and also their customers as well." Despite this problem being quickly reported to McAfee and it being stressed to them that this is a major problem which is causing damage to many businesses, they have been very slow to react. Although they have now responded and admitted that this is
a problem with their software, they have still not released a new update to their DAT files to fix the problem and say that it may take until Thursday [September 9th] before it is actually released. In the meantime, the software continues to misidentify my software as being infected by a Trojan. End users that are being affected are either contacting the ISP for assistance and blaming them for distributing a Trojan - greatly increasing the support burden and costs for the ISP, or they are simply switching to another ISP, he added.

The users who deal with other AV software solutions do not experience these problems. Why does McAfee, nobody knows, but it was suggested that the misdiagnosis could have arisen because components of ISPWizard were created with the same package as components of the backdoor Trojan program. But this remains only a theory. McAfee has offered Griffiths a temporary DAT file that end users would need to manually install on their systems as a workaround. Griffiths is unimpressed with the offer: he is frustrated that McAfee has not released an emergency automatic update.
