9 advice Get a Firewall If you’re connected to the internet through a router, then you already have a type of hardware firewall that prevents random networking-based external threats from reaching your computers. If you’re using a dial-up internet connection, a firewall may not be as important, although it doesn’t hurt to have one A virus scanner will locate and remove them from your hard disk. A real-time virus scanner will notice them as they arrive, even before they hit the disk, but at the cost of slowing down your machine a little, and occasionally even interfering with other operations. Spyware is similar to viruses in that they arrive unexpected and unannounced and proceed to do something undesired. Spyware can be relatively benign from a pure safety perspective, as it might “only” spy on you. But that’s enough. It can violate your privacy by tracking the websites that you visit, add “features” to your system that you didn’t ask for, or record your keystrokes and steal your account login information for any online services that you might use. Some of the worst offenders are spyware that hijack normal functions for themselves. 90% of virus infections don’t have to happen. Software vulnerabilities that malware exploits usually already have fixes available by the time the virus reaches a computer. The problem? The user simply failed to install the latest updates that would have prevented the infection in the first place. Backing up doesn’t feel like a “security” measure, but ultimately, it can be one of the most powerful ways to recover if you even encounter a security related issue. Having a recent backup to restore to can quickly undo the damage done by almost any form of malware. Having a back copy of your data (all your data) can help you recover after computer is lost or stolen (not to mention when a hard disk dies). INTERENT SAFETY
