When you buy a Kaspersky ONE Universal Security license, you will have one of the best computer security software products. You can select up to five devices to protect. The five devices can be any combination of Windows PCs, Apple computers and Android devices. Kaspersky security is strong. The feature set is attractive. Help and support are excellent.

Multi-Device Protection
Although Kaspersky ONE Universal Security can protect Windows machines and Apple computers, it goes beyond computer protection to include Android tablets and Android smartphones. One purchase covers any combination of five devices that you can manage all together from your online Kaspersky account.

When Kaspersky participated in performance tests conducted by AV-Test in December 2012, the Windows version turned in excellent scores in two areas: detection and prevention of attacks from previously unknown malware, and disinfection of computers on which malware was already resident. It also scored well in a third area, usability. When AV-Test looks at usability, it runs tests to check the degree of the toll that the computer security software takes on computer system resources. Another aspect of usability it considers is how accurately the PC security software labels whether files are friendly or malicious. Kaspersky is consistently among the top three performers in AV-Test results and has remained among the leaders for years.

Features
The PC portion of this computer protection software includes a firewall and parental controls. It also guards your digital identity, protects you from phishing attacks, and protects your online banking and shopping sessions. It prevents you from visiting dangerous sites and blocks banner ads. If you want to enter a password without falling victim to keyloggers, you can launch a virtual keyboard.

The Mac portion stops Mac, PC and Linux malware. It warns you about phishing attempts and dangerous links. It also has parental controls and a virtual keyboard.

The Android tablet and smartphone modules protect against malware and dangerous links. They also have antitheft features so that you can locate the device and use it to take pictures of the thief. You can also wipe the data on the device remotely. The Android smartphone features add a phone-specific feature: the ability to filter unwanted calls and instant messages.
