What malware do you hate the most? As Hulk would say: 'All malware BAD!' But the worst is probably the one my family or friends download—and I have to deal with.

Favorite activities: Time with my family, gaming, making good coffee and drinking it, boxing workouts, freeride snowboarding.

Golden rule for cyberspace? If something looks too good to be true, it probably is.

When did you get your first computer and what kind was it? Around 1994, a 286 with MS-DOS preinstalled. There was no monitor, so we could only use it when no one wasn't watching the TV.

Favorite computer game / activity: Mostly strategy games such as Warcraft II, Starcraft, Settlers, C&C series, RPGs like the Baldur's Gate, or Diablo, and basically anything with an open world.
