Antivirus software shields your PC from phishing scams, malware and other malicious files which steal information or slow down the computer. These programs scan for threats and take them off if detected. Some also offer additional security features, for instance a fire wall that can help keep your computer safe from attacks by networks. Some are free while others require a fee to offer complete security.
When selecting antivirus software select a program that uses minimal resources so that it does not slow down your computer while performing virus scans or other operations. You can use the search feature of the program to locate reviews from other users. This will help you determine whether the software is efficient and does not use up too much memory and space on your hard drive or other resources.
The most effective antivirus software will identify viruses reliably and quickly. They can use a combination of methods, including specific detection, which searches for known viruses; generic detection, which detects specific various types of malware as well as heuristic detection which analyzes behavior to detect suspicious patterns. Once a virus is identified the program will then isolate it from other files or programs and block access to it and delete it. Some programs will show an alert that indicates that the threat has been detected or removed.
If you’re looking for the best antivirus program, look for one that comes with additional security features such as parental controls as well as a cloud scanner and ransomware protection. Other features include a free trial or money-back guarantee, compatibility with various devices regular updates, and customer support.
