PC pranking

Leaving your unattended computer unlocked is no joke. According to research from Kaspersky, 21.3% of South African computer users have faced a situation where, having left their PC unlocked, a colleague, friend or relative has pulled pranks with it, such as sending messages pretending to be the user. But who these pranksters are remains a mystery, as just 3.3% of respondents admitted to pulling such stunts.
