Antivirus software keeps your computer secure from malware, phishing scams and other malicious files that steal information or cause slowdowns. These programs check your PC for these threats and remove them when they are discovered, and some include additional security features, such as firewalls to guard against attacks on networks. Some are completely free, while others require a monthly subscription fee for complete protection.

When choosing antivirus software, look for a program which uses a limited amount of system resources so it doesn’t slow down your computer when scanning for viruses or other functions. You can use the search function of the program to search for reviews from other users. This will let you know whether a specific program is efficient and doesn’t consume too much memory or space on your hard drive or other resources.

The most effective antivirus software will detect viruses quickly and efficiently. They may employ a combination of methods that include specific detection, which searches for known viruses; generic detection, which can identify various types of malware; and heuristic detection, which looks at behavior to spot suspicious patterns. Once the virus is identified, the program will isolate that file or program from other programs and files, block access, and then delete it. Certain programs will display an alert that indicates that the threat has been identified or removed.

Anyone looking for the best and most secure antivirus program should look into one that offers additional security including an firewall, a cloud-based scanner, parental controls, and ransomware protection. Other features include a money-back guarantee or free trial, compatibility with a variety of platforms, frequent updates and customer support.
