Antovirus scan uses GPU processor as well?

Been using firewall since version 6.something, never had problems so never registered here to ask for help. Today I switched to comodo antivirus to give it a try, and something strange happened.

Cpu load aside, I noticed in Afterburner Gpu values going up to a steady ~25% usage, Im pretty sure that never happened before.

cis.exe does appear on nvidia’s utility which shows what applications run on the gpu. I do a lot of gaming, graphic design and heavy video editing in my free time, and 25% of my GTX 780 Ti can have an impact on what I’m doing if the AV decides to scan something meanwhile, so is normal or it’s just during full/quick scans?
