In addition, Kaspersky Anti-Virus 2011 caused a somewhat larger hit on overall system performance than most other antivirus packages we looked at. The test PC started up in 54 seconds with Kaspersky installed. This put it well behind the average startup time for the test PC with antivirus software installed (46.5 seconds), and it represents a nearly 14-second increase over the startup time with no antivirus software installed (40.1 seconds). Kaspersky slowed file copy and download tasks more significantly than other suites as well.
