If you’re serious about your computer and don’t want to be harmed by malware, then antivirus protection is a must. Antivirus software scans files, programs and incoming emails for viruses and then deletes or quarantines anything it detects. The best antivirus software is compatible with all operating systems and utilizes the smallest amount of resources to not slow down your system or crash it. The majority of antivirus programs should be regularly updated to keep up with the latest ‘bugs’.
Antivirus programs can protect you from a range of malware. There are trojans, viruses, malware (which appear to be safe programs, but actually steal information or attack another device), and spyware that tracks the words you type, which can reveal your password and account details or bombard users with irritating ads and notifications. A lot of antivirus programs also have detection of rootkits that can detect malware that is hidden deep within your system. They also have heuristic detection that searches for patterns and tendencies in how files or programs behave to detect what signature-based virus scanners may miss.
A good antivirus program should protect your PCs and laptops against a wide range of threats. It should also work across desktops, tablets and smartphones. It should also be lightweight and simple to configure and use, and not rely on a “real-time” scan that can slow your system. The most effective antivirus document scanning process software is constantly evolving to stay ahead the curve; a good indicator of how often it updates its virus definitions, and you should look for every day or at the very least weekly updates.
