Free Kaspersky Antivirus for Windows
Kaspersky is famous for its success in identifying and stopping viruses. After Microsoft managed to make of Windows Defender a rather strong security application, Kaspersky decided to release a free version of its software for Windows.
Kaspersky Free protects against various types of information security threats, network attacks, and fraud. You can enable and disable protection components, and configure their settings.
Kaspersky Free comprises: File Anti-Virus, which protects the computer file system, Mail Anti-Virus, which checks inbound and outbound mail for viruses and other malicious programs, Web Anti-Virus, which intercepts and blocks scripts on websites should they pose a threat (dangerous websites are blocked automatically), IM Anti-Virus, which maintains security while using instant messaging applications, Anti-Phishing, which checks whether web-addresses are on the list of phishing websites, On-Screen Keyboard, which prevents malefactors from intercepting information that the user enters with a standard external keyboard.
Kaspersky Free includes all the essentials: file, email and web antivirus; automatic updates, self-defense; quarantine; and so on. It is also lighter on system resources and quicker than its big brothers.
