Kaspersky Internet Security 2021 is a powerful suite of malware-hunting, anti-hacker, web safety tools. 

There's antivirus. Browsing protection. A firewall. Exploit protection. A vulnerability scanner, parental controls, webcam and audio protection, online transaction protection, and more.

These features have real value, too. Independent testing labs such as AV-Comparatives typically rate Kaspersky as offering some of the best protection around.

There's the Software Updater, which checks for updates to common applications (Adobe Reader, Flash, Java, Chrome, Firefox, more), and can optionally install them without you having to see or do anything at all.

A "Secure Connection" feature is essentially a privacy-oriented VPN (virtual private network), automatically kicking in to protect you when using wifi hotspots, web banking sites and more.

An Installation Assistance tool looks out for adware and other pests that get silently installed with some "free" software, and the Software Cleaner helps you decide what to remove.

What's new in Kaspersky Internet Security 2021? Your computer is now protected whilst it's either booting or restarting, there's better protection against third-party manipulation of files on your hard drive, additional notifications to warn against potential malicious websites and, for any reseller, Kaspersky has made it much easier for a user to be able to add a new licence to an expired subscription rather than forcing the user to renew.

Includes a 5-Device, 1-Year license.

Special Information

You'll receive your Kaspersky Internet Security 2021 license code, plus download instructions for all devices, after purchase. You can download other trial versions from the Kaspersky Internet Security 2021 website, here: http://support.kaspersky.com/#s_tab2

You receive a single license with Kaspersky Internet Security 2021. Your license can activate Kaspersky Internet Security 2021 (PC), Kaspersky Internet Security for Mac v21 and Kaspersky Internet Security for Android (Android). You can use your 5-Device license to activate either one of these applications, five times, for one year.

Performance Issues?

Most system performance issues are often a result of other software clashing with your brand new software. For instance, security software can clash with a background process, such as a system maintenance tool or defragmentation software. Another cause of system slowdown, is a result of two software applications performing a similar task. As an example, Windows includes a firewall switched on as a default. Your new security suite is likely to include a firewall. You only need one firewall running. In this example, try turning off your system firewall.

Uninstalling Your New Software

Occasionally you may need to either temporarily or permanently remove your new software.

On a Windows computer, go to the Control Panel and choose Programs and Features. Locate the program within the list, then click it to highlight it. Finally, click the Uninstall button at the top of the list and follow the instructions to remove the program from your PC.

On an Apple Mac computer, using Finder, locate the Applications folder. Within the Applications folder, find the name of the application you wish to remove. Simply drag the icon to your Trash icon in your dock. Empty the Trash to remove the files from your computer.

Still Having Problems?

If you cannot solve your system performance issues or are struggling to remove your software, we advise contacting the software manufacturer. If you placed an order, see the section in the order which states Support options. Alternatively, go to the Contact Us page to contact store support directly.
