Huge freeze

[Lord 15]

Hello !

Since today, i have huge freeze when i launch 2 or + bots on my computer .. 
The computer himself can handle more than 8 accounts usually, and now when i start a second session ( Vanilla ), my all computer go freezing .. 

My firewall did catch Wrobot after update last day, may it come from here ? Reinstalling wrobot could resolve this ? Or maybe its not at all wrobot .. ( i checked my performance, all around 30% CPU 30% memory 1% HDD ... 

 

The freeze appear randomly when i have a wow window open, make my mouse unable to move for 1 sec when it happens ..  and in overall, the game looke slow, with i'd say 30 40 FPS maximum ..

 

Any people experimented the same thing ?

EDIT : look to happen only on Vanilla server ( Elysium ) & only on one character .. x)

So apparently its coming from wow application .. when i start a 2nd session, this one start to freeze and all my actions look delayed of 0.5 sec .. ( sometimes my character start doing my actions 3 / 5 sec after .. ). Its not a lag, its not coming from the computer performance .. Virus ?
