Very slow work antivirus

Very slow work antivirus. In some cases, blocking the operating system (windows 7 SP1 x64) and other program.
For example. Install netbeans 8.1, then delete the contents of the directory \AppData\Local\NetBeans\Cache\8.1
If you disable the antivirus software before you start the NetBeans, the operation “build dictionary” (which in this case is run) is performed for a few seconds.
If the antivirus software is enabled, the operation is “build dictionary” is performed for more than 10 minutes (when you run NetBeans). Disable antivirus, after the start of operations “Build dictionary” does not help.
This behavior may occur in many other cases, but hang at startup netbeans consistently played on my computer.
Antivirus work in cumulative mode.

What happens when you add the Netbeans cache folder to the Excluded Paths under Exclusions?

Are there other reproducible scenarios with performance issues?

So far I have not found other stable reproducible scenarios.

Sorry, I hooked up an SSD drive in IDE mode instead of AHCI.
Apparently with this and have been associated problems
