If you’re serious about your computer and don’t want to be harmed by malware, antivirus protection is a must. Antivirus software scans incoming emails programs, files, and emails for viruses and removes or quarantines any it detects. The best antivirus software works with all operating systems and requires minimal resources to ensure it does not slow down or crash your PC. Most antivirus software should be regularly updated to keep up with the most recent ‘bugs’.
There are various kinds of malware that antivirus programs guard against. These include viruses, worms and trojans (which behave like safe programs but take your information and attack other devices), plus spyware that monitors what you type on the keyboard to reveal passwords and account information or flood you with annoying ads and notifications. Many antivirus programs also include rootkit detection technology that spots malware that is hidden deep within your system, as well as heuristic detection that searches for patterns and trends in the way files or programs behave to detect what signature-based virus scanners may miss.
A reliable antivirus program can protect your PCs and Laptops from a range of threats. It should also work on tablets, desktops, and smartphones. It should be light and user-friendly and easy to configure, and shouldn’t rely on “real time” scan processes that can slow down your system. The best antivirus software is constantly changing to stay ahead of the game. A good indicator of how often it updates its virus definitions and you should try to get daily or at least weekly updates.
