Is CIS AV a sprinter ?

Hello,

Windows 10 Family up to date, CIS Premium 7062
sfc /scannow : no violation of integrity

Full scan with heuristics scanning medium : after 58 minutes the progress rate was 48%. 3 minutes later the rate was 100%
Full scan with heuristics scanning low : after 30 minutes the progress rate was 50%. 1 minute later the rate was 100%

Is CIS AV working faster on the end ?

That depends on us PC, but programs antivirus delay check or scanning :-TU
