An antivirus is a computer security software that is developed to detect and remove various types of viruses and malicious software’s (like Trojans, spyware, adware and rootkits).
Antivirus software usually used two basic methods for detecting, blocking and removing viruses. These methods include:
• Signature based scanning
• Behavioral Scanning
Because it relies on signatures and patterns, anti-virus software can only detect viruses that have signatures installed on your computer. As new viruses are written every day, anti-virus vendors provide regular updates to their product. Therefore it is necessary to keep the option to automatically receive updated virus definitions “Enabled”.
Some of the consideration for selecting the best antivirus for your computer are :
• Ability of antivirus software to detect all types of malware
• Ability of antivirus software to remove that malware
• Effect of the software on performance of computer and its efficiency
• Price of the antivirus
• False Positives (Lower number indicates better performance)
