Hello, I have checked this installation file about its digital signature. Do you uncheck the KL application control settings : trusted digitally signed application? By default, I can not encounter this issue. It is not a self-signed digital verification. I change my previous idea. This file is signed by Sectigo. As for why Kaspersky does not trust the sectigo certificate authority, this reason requires Kaspersky to confirm the reason. Regards.

Hello, 是的，就是这个原因。你目前保持默认即可，无需作任何操作。

Hello, @T,X Programs that change your mbr are not necessarily malicious programs, such as disk programs such as diskgenius. Why do you say it changes the mbr information? The key is to see what happens after changing the mbr information, locking the system and ransome you, because changing the mbr information is used to do this kind of malicious behavior. I believe this program does not have this behavior. I think this program set the boot item for you. not use mbr section. Just edit the boot.ini file in driver C root folder. Regards.

Hello, @T,X Do you really don't know what is "DriveTheLife" in china ? If you want to restore the mbr information to default, Please use this system command which only available in windows 7, but you should backup the disk first and execute this command : fdisk /mbr Usually this command will not lead to lose disk data, but we are afraid of losing data in case. Regards.
