Many antivirus programs look for malware and viruses. The best ones also provide real-time protection, which monitors for shady websites, suspicious hyperlinks and other bad behavior. They’ll also analyze the files you download and monitor their actions to identify new threats, which aren’t yet known to be. Nowadays, a good antivirus program should be able to detect and remove ransomware. Some products accomplish this by Sandboxing. This is the process wherein suspicious encrypted files are put in a separate area of the operating system and then tested before allowing them to impact the rest of the computer.

The most effective antivirus suites consume little resources on your system and are fast to run. They do not just scan for viruses and malware but also safeguard your privacy, by encrypting emails and monitoring social media sites and ensuring that online transactions and banking are done with secure connections. Certain suites come with other useful tools like password management and shredders for your files. They also provide web protection to ensure safe shopping.

If you decide to pay for a program, be sure that it covers all the devices and operating systems you’d like to secure. Many of the top picks are compatible with all major platforms, including Windows PCs (three out of four desktop and laptop computers), macOS and iOS. Some of the more sophisticated paid antivirus programs can be used on Android devices. However, you will be required to check each vendor’s site for specifics. Some vendors will provide an actual copy of their product in electronic stores, however most will send you a code to download the software from their website or app store.
