This issue mainly effected companies in the USA and Australia as they were starting their business day just as the update was made available. By the time the UK started work McAfee had already issued a new update without the glitch. Fortunately this did not affect any Fifosys clients.

Barry McPherson, executive vice president of support and customer service, said on the company’s blog

“As you know, McAfee on Wednesday released a faulty signature update file (DAT file) that caused problems for a number of our customers.

First off, I want to apologize on behalf of McAfee and say that we’re extremely sorry for any impact the faulty signature update file may have caused you and your organizations.

I want to give you a brief update on what has happened since we first became aware of the false detection. McAfee team members have been working around the clock to fix the problem and work with impacted customers. We estimate that the majority of the affected systems are back up and running at this time and more systems are coming back online quickly.”

Do let us know if you were affected and need any help.
