Antivirus software protects your computer from phishing scams, malware and other malicious malware that steals information or slow down the computer. These programs look for threats and remove them if detected. Certain programs also include additional security features like an alarm system to help protect against attacks on networks. Some are free while others require a cost to ensure complete protection.
When choosing an antivirus software choose a program which uses a limited amount of system resources so that it does not slow down your computer when scans for viruses or other tasks. You can use the search feature of the application to find reviews from users. This will let you know whether a specific software is efficient and doesn’t use too much memory and space on your hard drive or other resources.
The best antivirus programs will detect viruses quickly and accurately. They may employ a combination of techniques, including specific detection, which scans for known viruses; general detection, which detects specific various types of malware and heuristic analysis, which analyzes behavior to detect suspicious patterns. Once the virus has been detected the program will then isolate that file or program from other files and programs, block access to it, and remove it. Some programs may display an alert signalling that the threat has been eliminated or identified.
Those looking for the most secure antivirus software should consider one that offers additional security, such as firewalls, cloud-based scanner, parental controls and ransomware defense. Other features include a money-back guarantee or free trial, compatibility across multiple platforms, frequent updates, and customer support.
