arduino IDE slow to start up - has anyone found turning off AntiVirus fixes it?

i'm running the free version of panda, so behavioural analysis is locked in the 'off' position. have also turned off behavioural blocking, but this produces no improvement. have also set the delay for cloud response down to the minimum (10 seconds)

BUT, have observed the following interesting thing: the panda process PSANHost.exe is generating around 1,700,000 (1.7 million) i/o reads while the arduino IDE is attempting to start up. if i turn panda off, then obviously it doesn't generate these reads, but they don't reappear anywhere else. the process javaw.exe generates less than 10,000 i/o reads irrespective of panda being on or off.

so, what can the arduino IDE be doing to generate this much i/o activity in a antivirus program??? i am wondering if it is an 'odd' behaviour of the arduino IDE - not necessarily a bug, but perhaps just something unexpected - exposing a bug that exists in panda (and potentially other antivirus software).
