small office security uses memory too much ( i think)

[totoya]

when computer turn on, it uses about 30% memory(2.5GB) normally.

but recently it uses 50% memory ( 4GB).

so i open resource monitor.

avp.exe( PID : 1688 ) and avpui.exe ( PID : 22756 ) use about 20% memory.

I think it is unusual.

could somebody explain about it?

i solved the issue.

it was brave brower. it used memory even if it turned off.

i am curious. it was not detected by monitoring program.

OS is window 8.1
