CNET 2006 antivirus performance test scores

CNET Labs compares the performance of antivirus apps.

By Robert Vamosi (April 7, 2006) 		Reviews

Testing done by CNET Labs focuses on how a given antivirus scan affects the performance of a few real-world tasks. To see how a given antivirus app performs when stopping malicious code, we recommend viewing the latest test results published by independent antivirus testing organizations AV-comparatives and Checkvir.com.

Antivirus scan impact on system performance
To determine the impact an antivirus scan has on your test PC, we chose two popular apps--iTunes 6 and Sorenson Squeeze 4--and performed common tasks such as encoding music and compressing video. While performing these common tasks, we also performed both real-time scans and deep scans with the antivirus apps. Our real-time antivirus scans didn't show much degradation. However, our antivirus deep scans did offer some interesting differences.
