UPDATE: Kaspersky Free antivirus has been discontinued and you get Kaspersky Security Cloud Free now instead. This one gives you remote control and management options that Kaspersky Free Antivirus does not support. That is the main difference between the two.
Kaspersky Free Antivirus for Windows PC
Kaspersky Free Antivirus offers basic anti-malware protection for Windows users like file, email and web antivirus, automatic updates, self-defense, quarantine, etc; and will not include advanced security features like Privacy Protection, Parental Control, Safe Money, Online Payment Protection, Secure VPN Connection, etc., which paid products like Kaspersky Internet Security have to offer. As a result, it is expected to be lighter and quicker. Said Eugene Kaspersky, Once you download the installer and run it, you will be welcomed with the following screen. Click on Continue to proceed with the installation.
Once Kaspersky Free Antivirus is installed, reboot your computer and open it. The UI is easy to understand and operate.
You basically have two buttons that will work for you. The Scan button and the Database Update button – if you need to manually perform these operations. Clicking on the small wheel in the bottom left corner will open its Settings.
You can configure the settings for File Anti-Virus, Web AntiVirus, IM Anti-Virus and Mail Anti-Virus. Click on the thumbnails to see the settings for these functions. You can go here to download the setup file for Kaspersky Free Antivirus.
