Apparently 4 out of 5 alerts reported by malware-detection products are false alarms <http://arstechnica.com/security/2015/01/survey-says-security-products-waste-our-time/>. And of course the result is predictable: In 2013, for example, when cybercriminals broke into Target’s systems and loaded malware, the company’s FireEye security system issued an alert for the activity, but the company ignored the alerts. As a result, a District Court judge in Minnesota has given the go-ahead for banks to sue the retailer.
