Timely reminder from BBC Online.
The 20th anniversary of the first PC virus falls this month.
It was during the opening weeks of 1986 that the first PC virus, called Brain, was discovered in the wild.
Though it achieved fame because it was the first of its type, the virus was not widespread as it could only travel by hitching a ride on floppy disks swapped between users.
Now 20 years after they first appeared there are more than 150,000 malicious programs in existence.
That’s why my colleagues and I created our online course, Vandalism in Cyberspace: understanding and combatting malicious software.
