Once the leader in cybersecurity, Symantec has declared that "antivirus is dead", at least as a business model. This is obviously true, considering the proliferation of excellent free antivirus software. Antivirus is also pretty stale as a technology:
Ted Schlein, who helped create Symantec's first antivirus product, describes such software as "necessary but insufficient." As a partner at venture-capital firm Kleiner Perkins Caufield & Byers, Mr. Schlein invests in new cybersecurity companies that compete with Symantec.
Using antivirus software is like locking the door of your house. It's a smart thing to do, but it won't protect you if you expose yourself to danger in other ways.
