I have same folder named "Avital" with 2 x files :
shaiya64.sys
sysken64.sys
Digital signature shows they originate from Beijing Apex Weifeng Technology Co Ltd
There's also an email address and site for
service@apexanti.com
The site takes you to a webmail site in chinese!
Gonna delete and re-install Shaiya and see if the same folder appears, it may be from a recent update though as it was created on 14/12
