Let me see whether I got this right. The AES16 is a digital only card. So it must be that the Virus scanner is checking for viruses each time the crystal oscillator on that card wants to make one clock tick and that is impacting the sound ...But seriously, what DAC are you using? The only issue I can think of is that somehow the background programs impact the crystal on the card via the power supply or ground plane.
Are you using some form of upsampling where the CPU could actually make a difference?
