Antivirus software helps keep your computer free from malware, phishing scams and other harmful files that steal information or cause slowdowns. These programs search for threats and eliminate them if identified. Certain programs also include additional security features, for instance a fire wall to help keep your computer safe from attacks by networks. Some programs are free, while others require a cost to ensure complete protection.
When choosing an antivirus program Choose a program that utilizes a minimal amount of system resources to ensure it doesn’t slow your computer while performing the virus scans or other actions. Utilizing the search feature of the program to read user reviews can help you determine which ones are efficient and do not use up too much memory, disk space, or other resources.
The most effective antivirus software will detect viruses efficiently and quickly. They employ various methods, including specific detection which searches for known viruses, generic detection that recognizes different parts and types of malware and heuristics detection which examines patterns to determine suspicious behavior. Once the virus is identified the program will then isolate the affected program or file from other files and programs, block access, and delete it. Some programs will display an alert that indicates the threat has been removed or detected.
If you’re looking for the best antivirus program, consider one that provides additional security such as parental controls and a cloud scanner and ransomware protection. Other features include a money-back assurance or free trial, compatibility with various platforms, frequent updates and customer support.
