Why is Kaspersky 2009 so stuck?

I have been using Kabbah for three years. According to your question, I have summarized the following two reasons.

1, Settings: Take a good look at the settings. There may be something wrong with the settings, such as updating the settings every day!

2, its own system: because 8.0 has full functions and full coverage, the CPU utilization rate has also increased a lot, but you said that this situation should not happen. If Kaba is uninstalled, it will certainly not change much. I think this may be a system problem. Of course, including viruses in the system.
