Antivirus software protects your computer from malware, phishing scams, and other malicious files which steal information or slow down the computer. These programs search your PC for these threats and remove them if they are detected. Additionally, some also offer other security features, like a firewall to help prevent network attacks. Some programs are free, while others require a subscription fee to provide complete protection.
When choosing antivirus software select a program that requires minimal system resources to ensure it does not slow down your computer while performing scans for viruses or other tasks. Utilizing the search feature of the program to read user reviews can aid you in determining which are effective and don’t consume too much memory, disk space, or other resources.
The most reliable antivirus software can identify viruses reliably and quickly. They can use different methods such as specific detection that searches for known viruses, generic detection that identifies components and types of malware and heuristics detection that analyzes patterns to detect suspicious behavior. Once an infection has been identified, the program will isolate that file or program from other programs and files then block access and delete it. Some programs will show an alert that indicates that the threat has been identified or removed.
For those looking for the most secure antivirus software should consider one that offers additional security like firewalls, cloud-based scanner, parental controls, and ransomware protection. Other features include a money back guarantee or free trial, compatibility with multiple platforms, frequent updates and customer assistance.
