Hi.I recently noticed high HDD usage in task manager about 9 MB/s and upper in 2 laptops.In other laptops with the same version and configuration everything is calm about 0.2 MB/s.I tried disabling Cloud Scanning and File Rating with no chance.I think there is a module that never gonna satisfied and stopped. 
Any idea to fix it?
I found the cause in one system.It was the NetBalancer program service.After stopping service ,HDD usage by comodo is normal.
