An error occurring in the update of Norton's virus database on Friday has caused millions of PCs and computers to crash-a heavy blow to people's daily work and ongoing business.
The common symptom is that the computer may suddenly encounter a blue screen and then be prompted with an error message. The same problem remains even after a reboot of the system.

Wow I didnt expect anything like this. I'm currently running Kaspersky for AV and internet security suite.
