If you’re serious about your computer and don’t want to get taken down by malware, protection from antivirus is a must. Antivirus software scans emails programs, files, and emails for viruses and removes or blocks any viruses it finds. The best antivirus software is compatible with all operating systems and uses very little resources, which means it won’t slow down your computer or crash it. The majority of antivirus software needs to be regularly updated to keep up with the most recent ‘bugs’.
Antivirus programs can protect you from a range of malware. There are viruses, trojans, worms (which appear to be safe programs, but actually steal information or inflict harm on another device), and spyware that analyzes what you type to expose your password and account information or bombard users with irritating ads and notifications. Many antivirus programs incorporate rootkit detection technology that can detect malicious code that is hidden in your system. Heuristic detection also scans for patterns and recurring patterns in the way programs and files behave in order to catch the malware that signature-based scanners might miss.
A quality antivirus program should safeguard your laptops and PCs against a myriad of threats. It also works across tablets, desktops and smartphones. It should also be light, easy to configure and use, and not rely on a « real-time » scan process that could slow your system down. The best antivirus software continually adapts to stay ahead of trends. You should test it by observing how often the virus definitions are updated. You should aim for at minimum weekly or daily updates.
