When it comes to specialized, but comprehensive solutions for PC protection, one cannot help but remember the name Kaspersky. The reputation precedes the products, and for good reason.
Online Defender
The most appealing thing about Kaspersky Internet Security is its fully automated threat prevention. You just install it, and the program does the rest for you: scans, updates, detects, blocks, and removes all kinds of malware, spyware, trojans, viruses, bloatware or other leeches that a computer might catch when accessing the Internet. The option to check every webpage is rather nice, as well as download monitoring.
Drive Protection
But the security measures of KIS do not end at browsing and downloading stages. It also checks the files already present on your drives, controls the unpacking and installation of downloaded software, and generally keeps an eye on things like regular antivirus. Coupled with one of the largest virus databases around, this is a hefty bonus.
Additional Features
KIS is regularly updated and introduces additional online protection modules, such as network monitoring, camera and microphone checks, parental locks, etc. The most interesting of those is Safe Money - a tool for securing financial transactions in Internet shops and on payment platforms.
Summary
Despite a few shortcomings shared with alternatives like the AVS product line like being rather over-cautious and producing false positives when downloading and launching archives and executables, Kaspersky Internet Security is what it is supposed to be: thorough, easy to use, and reliable.
