Norton Causes IE Crash

A crash problem with Internet Explorer ended up triggered by a corrupt file in the Norton virus definition set, researchers said.

The update was with the Intrusion Prevention System (IPS) 20150220.001 definition package, Symantec said.

The corrupt IPS definition package caused the 32-bit version of Internet Explorer to crash on computers running Norton Security, Norton Security with Backup, Norton 360, and Norton Internet Security, Symantec researchers said. Other Web browsers don’t appear to suffer from the issue.

Symantec Endpoint Protection 12.1 might also feel an impact from the issue, but only if the client receives content from a pre-RU2 Symantec Endpoint Protection Management (SEPM) server, or if the client is pre-RU2 and runs LiveUpdate directly to Symantec.

The company addressed the issue by releasing a new version of the 20150220.001 definition package through the LiveUpdate service.

“Definition package updates are automatically deployed by Norton and Symantec Endpoint Protection every four hours, unless users manually download them for unmanaged computers or administrators manually deploy them to their managed clients from the SEP Management Server. Users can also manually deploy the update before it is deployed automatically,” Symantec said in an advisory.

The company also published a help page for users who encountered this issue.
