How to Selecting Free Antivirus Software
Now let’s get this clear. It’s a sheer myth to believe that Apple or Mac computers, as we know them, are immune to virus attacks. No, they’re not. Since fewer Apple computers, the number of virus attacks is relatively lower.
Some people believe that Apple or Mac computers don’t get affected or attacked by viruses. The answer is NO; they also can be attacked. They are not immune to virus attacks, but the rate they are being attacked is meager compared to other operating systems. About 77% of computers use the Windows OS. Hence, they are common targets for virus attacks.
Furthermore, users have to select antivirus according to their region or country because all antivirus software needs updates. Whenever an antivirus company detects a threat in your region, it will be used as an update to protect your computer.
Note that it does not mean you should stop downloading antivirus updates because hackers are not targeting your region. It’s advisable to update your antivirus, and before you download it, we recommend you read users’ guides on antivirus on how to defend your computer.
