One of the cardinal rules for computer security is keeping your operating system and programs up to date. Up-to-date software has fewer security holes for hackers and viruses to attack.
Now, you might have heard security experts, including Kim, giving that advice for years and it's just become background noise. However, today you're getting a fresh reminder courtesy of the last people you'd expect: hackers.
Specifically I'm talking about the latest version of the Kovter Trojan. This virus sneaks in through security holes in browser plug-ins like Adobe Flash, Adobe Reader, Java and Silverlight.
Once it downloads, Kovter hijacks your computer and racks up thousands of phony clicks on online ads. That doesn't make it especially dangerous to you, but if it can sneak on to your system, it's a good bet something more dangerous can get in as well. Or at least that used to be the case.
