How to protect your computer from virus?
1. Keep your software up to date
Software makers like Microsoft and Oracle routinely update their software to fix bugs that could potentially be exploited by hackers. Oracle just released on Sunday an update to its Java software to fix a security hole hackers could have used to infect computers with malware.
2. Don’t click on links within emails
A good rule of thumb is if you don’t recognize a sender of an email, don’t click on any links within it. Microsoft says 44.8 percent of Windows virus infections happen because the computer user clicked on something.
3. Use free antivirus software
You don’t have to pay for software to protect your computer or for an annual subscription to maintain the latest virus protection. For Windows users, Microsoft Security Essentials is free.
4. Back up your computer
You have no protection from calamities ranging from hard drive failure to your house burning down. If you value your data, back it up.You have three basic backup options: an external hard drive, online backup service, or cloud storage. Use a service like Google Drive, and your files will be continually backed up to the cloud.
5. Use a strong password
A strong password is one that is complex, with a mix of letters, numbers, and symbols. While some people use the same password for everything, try to avoid that practice.
6. Use a firewall
Just because you have antivirus software running doesn’t mean you have a firewall. Both PCs and Macs come with built-in firewall software. Be sure to check that it’s enabled.
7. Minimize downloads
Make sure your Web browser’s security settings are high enough to detect unauthorized downloads. For Internet Explorer, the medium security setting is the minimum level to use.
8. Use a pop-up blocker
Web browsers have the ability to stop pop-up windows and allow you to set the security for accepting pop-ups. The federal On Guard Online site recommends never clicking on links within pop-up screens.Even the most vigilant of computer users still run the risk of picking up malware. You should suspect a computer virus if your machine slows down, crashes, or repeats error messages.
