The following are important steps you should consider to make your home PC or MAC more secure.

 

Connect to a Secure Network
Once your computer is connected to the Internet, it’s also connected to millions of other computers, which could allow attackers access to your computer. Information flows from the Internet to your home network by first coming into your modem, then into your router and finally into your computer.

 

Install Antivirus and Antispyware Software
Installing an antivirus and antispyware software program and keeping it up to date is a critical step in protecting your computer. Many types of antivirus and antispyware software can detect the possible presence of malware by looking for patterns in the files or memory of your computer.

 

Remove Unnecessary Software
Intruders can attack your computer by exploiting software vulnerabilities (that is, flaws or weaknesses), so the less software you have installed, the fewer avenues for potential attack. Check the software installed on your computer.

 

Secure Your Web Browser
Web browsers installed on new computers usually don’t have secure default settings. Securing your browser is another critical step in improving your computer’s security because an increasing number of attacks take advantage of web browsers.

 

Apply Software Updates
When you set up a new computer (and after you have completed the previous practices), go to your software vendors’ websites to check for and install all available updates. Enable automatic updates if your vendors offer it; that will ensure your software is always updated, and you won’t have to remember to do it yourself.

 

Use Good Security Practices
You can do some simple things to improve your computer’s security. Some of the most important are:
Use caution with email attachments and untrusted links. Malware is commonly spread by people clicking on an email attachment or a link that launches the malware. Don’t open attachments or click on links unless you’re certain they’re safe, even if they come from a person you know. Use caution when providing sensitive information. Create strong passwords.
