You’re not a fan of malicious code, spam or phishing. But you don’t want the headache of lengthy, complex lists of steps and precautions that you’ll never read, much less follow. These 10 basic strategies will help you keep the bad stuff away from your home or office computer, without the hassle.

1. Beware of suspicious email You might think an email is harmless -- but it’s better to be certain before you open it. Scan emails before you open them and think twice before launching executable (.exe) files attached to an email (like, don’t do it). Never open attachments in email from unknown senders, and never reply to spam (unless you consider a few choice words muttered under your breath a reply).

2. Neighborhood watch your network If you’ve got multiple computers linked together at home or at the office, keep an eye on the neighborhood. All network-connected computers and inbound/outbound traffic should be monitored for signs of unauthorized entry and malicious activity, ensuring that any infected computers are removed from the network and disinfected as soon as possible.

3. Patch, Upgrade, Repeat Protect yourself by getting the latest operating system and security software updates and patches right away. Also, upgrade your browsers to the latest versions as soon as they become available.

4. Encrypt like your hair’s on fire If you keep sensitive data on your PC -- and most people do -- encrypt it.

5. Layer your security Just like wearing layers protects you better from the cold, layers of security protects your PC better from the evildoers of cyberspace. Use antivirus software and firewalls, and keep all your security programs up to date. Antivirus definitions should be updated regularly. Also, make sure to enable the security settings on Web browsers and disable file sharing.

6. Back it up If you’ve got important data, back it up. Period. There are too many ways to lose information: human error, hardware failure, lightning storms, voodoo. The list goes on. It’s just as bad to lose data for these reasons as to lose it to malware.

7. Shore up your weaknesses What are your vulnerabilities? No firewall? Really, really old software? General bad luck? Take account of where you’re weak on computer security, and address the problem -- or problems.

8. Take your passwords to the gym The stronger your passwords, the more likely they’ll fend off devious intruders who are looking for weaklings they can bully. Passwords should have at least eight characters and should combine alphanumeric and special characters (“$,” “*,” “&” and symbols like that). You should also change your passwords every 45 to 60 days.

9. Whatever you do, don’t order the spam sandwich When it comes to malware, spam is usually where it begins. Spam not only gobbles up your valuable time, it also hogs bandwidth and storage space. Report spam if you can, and use antispam software whenever possible.

10. Physical security counts True, most PC security threats are virtual -- but problems can also begin in the real world. If your computer is open to snoopers, try a screen-locking feature, or just shut your system down. If you’ve got a laptop, lock it down with a cable. And whatever you do, don’t leave your passwords written down where someone can easily read them. Be extra mindful of physical security with PDAs and handheld devices, which are popular targets for thieves.
