Keep Software Updated
Your computer manufacturer sends out routine software updates. Some of these fix bugs that have been detected in the software you use, wish as Word, Pages or Java. Keeping your software updated to the most recent release reduces the chance that your computer will become infected.
If you've been ignoring those updates, take the time to fix that! With a Mac, you'll get a notification box, letting you know updates are available.
Use Trusted, Free Antivirus Software
Why pay for your antivirus software protection? Free versions exist—this way, you're more likely to download a good, safe protection. Face it. Paying for an annual subscription may get difficult, then you and your personal data is at risk of theft or being corrupted.
Once you have a good antivirus program downloaded, you'll be able to run it if you are concerned that a virus has slipped into your computer.
Learn to Recognize Dangerous Links in Emails
If you got an email from a name you don't recognize, be cautious. Pay attention to those red flags if a link was included. Don't click on it because it may contain malicious viruses, Trojans or malware.
Even if you know the person who sent the email, be careful about opening links. Their computers may have been infected with viruses. If you open that link, your computer is now infected.
If you are using a work computer that gets infected, your employer may have to use distributed tracing, which works to monitor and profile computer applications. This may be used more on computers using a micro services architecture.
Be Cautious About Downloading and Running Programs
Sometimes, computer software just isn't all that it's been promised to be. If you're looking at a download for your computer, it may be infected with malware. Or, the software is just bad.
Select only software program downloads from sources you know and trust. That is, if you want to download a browser, use the browser's official website, not from another site.
Back your Computer Up Regularly
People can never hear this often enough: Backup your computer regularly! If you do, your files will be protected from viruses and malware, not to mention the failure of your hard drive. If you don't regularly back up, all that data will be gone, or infected.
Create and Use Strong Passwords
Get creative with your passwords. Lower- and upper-case letters, a few numbers and even a few symbols. Use a different password for each account you use—never use the same password for every site you use.
Those too easy to remember "passwords," such as “1234”, ''ABCDE" or even "password" can be broken in seconds by a hacker.
Passwords should be eight characters or more.
Even better, download a free password manager, such as LastPass. Create and store your password in your vault. Create a good, strong password for your vault. When you open LastPass, it logs you in to sites automatically.
Delete Pop-up Notifications
“Your Adobe Flash must be updated." When you see this, do you click the link right away? Or do you delete the site and start a new search for the information you need?
Once you see that irritating pop-up, stop! Don't click on the "install" button, because you're inviting a hacker in.
Never Leave Your Computer Unattended
Whether you're at work or your favorite coffee shop to do some work, take your phone and computer with you when you need to order something or visit the restroom. You may as well post a sign, saying, "Steal my computer and phone!"
If someone takes it, they may hack into it and gain access to all your personal information, such as medical or financial information. This will usher in several months of frustration for you.
