Antivirus software protects you from a wide range of threats like viruses, Trojans and worms. It also shields you from spyware, rootkits and the phishing. Ideally, you want to select a software that provides security features such as password managers and a virtual private network (VPN). A VPN helps shield your online movements so they aren’t viewed or intercepted. Some programs also offer live chat or phone assistance, while others offer knowledge bases online to assist you in solving your problems.

The best antivirus is compatible with your operating system and won’t consume too much power. Certain applications that consume excessive memory or CPU power could slow down or even crash your computer. In addition, choose a program that constantly updates its virus definitions. This will keep your device protected from most recent threats.

Many of the most well-known antivirus programs have been around since years. McAfee is a classic on the market and comes in a wide range of laptops. Norton Power Eraser, its free tool, is a good alternative to online scanners. However it does not come with real-time protection or threat removal tools such as those offered by Norton 360, the premium suite.

Kaspersky is another name that is well-known, and the products of Kaspersky are sold at many major retailers. The Russian-owned company has been criticized for sharing information with the government, and for refusing to condemn Russia’s Avast antitrack premium key military intervention in Ukraine. Cybernews does not recommend any of their products.
