Kaspersky Internet Security 2011 worked as expected and did not bother me during everyday use such as working in Microsoft Office or gaming. The only slow-downs I noticed had to do with downloading files; before I could open files I downloaded, Kaspersky Internet Security 2011 took 15-30 seconds to scan them depending on the file size; mildly annoying, but better safe than sorry.

We evaluate the performance impact and system resource usage of using anti-virus software in two ways:

  • 1. Overall system performance measured before and after installation using PCMark
  • 2. Time it took to perform a full system scan

Our test system is an ASUS U45J Series (Core i3-370M dual-core, 4GB RAM, 500GB 5400RPM drive, Windows 7 64-bit).

Kaspersky Internet Security 2011 has about a 5% performance impact, which is minimal.

Time it took to perform a full system scan

Kaspersky Internet Security 2011 took just over one hour to scan 140GB of data, which is a good time though not the fastest we tested; ESET Smart Security 4 holds first place and is about 20 minutes faster than Kaspersky Internet Security 2011. Nonetheless, this time is nothing to complain about. Anything over two hours I consider a long time.

Conclusion

Kaspersky Internet Security 2011 impresses in more ways than one. It is extremely proactive — it actively scans web traffic and blocked all my attempts to get malicious files on the computer. Additionally, it includes an extensive set of security tools such as a vulnerability scanner, which found a number of problems with my setup. The parental controls are fantastic and allow parents to administer extensive control over their children’s Internet and computer usage, right down to blocking them from entering specific words. Also worth mentioning are the low impact on system performance and the easy-to-use interface.

The only real con with the software is its anti-spam module, which simply did not work with our Thunderbird email client; it did not block spam or addresses on our blacklist.

Unless the anti-spam feature is important, Kaspersky Internet Security 2011 is highly recommendable.

Pros:

  • Very proactive
  • Good interface
  • Excellent parental controls
  • Minimal performance impact

Cons:

  • Poor anti-spam module
  • Large download file
