Happy birthday, Brain.A

Unless you're in the antivirus business, it's probably not worth celebrating. But 20 years ago this month, the first PC virus was discovered.

Dubbed Brain.A, the virus got onto computers via floppy disk and infected the boot sector of PCs, according to Finnish antivirus maker F-Secure, which devoted a blog post and news release to the occasion on Thursday.

"While the virus 'Brain' itself was relatively harmless, it set in motion a long chain of events leading up to today's virus situation," F-Secure said.

Brain.A and other "boot sector" viruses are long extinct. The same could be said of the medium used to spread them.
