Along with the numerous benefits the internet offers, not the least of which is access to information 24/7, hackers and malicious entities roam the cyberspace, justifying the oft-used expression, "This is why we can't have good things."
Spear phishing, spam, malware, viruses, worms, ransomware - there's a whole battalion of them waiting in the sidelines to launch an attack, especially on unprotected, unsuspecting users. (For more information, this

This being the norm, leaving the security of your devices to fate is irresponsible. Keeping your computers and smartphones protected is paramount, the same way securing your house before you retire for the night is second nature for most people around the world.

The good news is that security software products to safeguard your devices - home computers, office computers, laptops, tablets, or smartphones - are plenty. The bad news is that there are so many of them on the market that it can be difficult to determine which best suits your needs. Those days when security software choices were a toss-up between McAfee and Norton are long gone.
