McAfree Antivirus Knocked Out The Computer After Run Update

Some time we use antivirus is to protect our computer from virus attack, but did you ever think that the one you use to protect your computer also may hurt you?

Today 22 April 2010, there were 10 percent of the Coles stores cash registers knocked out after performing an update from McAfree.

The root cause of this incident is due to the antivirus update files misidentified a valid Windows file as a malicious code, therefore it cause the computers keep on reboot.

I don’t understand why this can be happened in production? They didn’t perform UAT testing to confirm error-free only roll it to production? They didn't know once it launches to production and may affect the business if the customers use it.

Some time open source can do it better than the commercial product like Avira and AVG.

This problem only will fix after the next release of update so waiting for it to download if you hit the problem.
