Hello
With HitmanPro, you can set the boot scan function yourself in Settings and this is applicable to your stated operating system W8.1. The HMP scanner is a 30 day free trial only, then it's subscription (pd). There is a PDF near the bottom of the page under "Comprehensive Remediation" that contains more detailed information..

Re: the Kickstart which you inquired about specifically. this does not appear to be compatible with your operating system.
HitmanPro Alert is an anti-exploit software that includes the scanner but without the capability to make any adjustments in the scanner settings. The scanner is for immediate use following a notification from the Alert about a possible exploit but you can use it as an on-demand also.
