Issue: How to fix K7Sentry.sys Blue Screen error in Windows?
Hello, I have recently installed the new security program K7 and noticed that by system sometimes started to crash with Blue Screen (K7Sentry.sys). I am using Windows 10. Do I need to uninstall antivirus, or is there another way of fixing this?
Blue Screen of Death crashes are something that users never expect, and because they come without warning, they can result in a rather frustrating experience. Work disruption, unsaved documents, interrupted gaming sessions, and many other disturbances can result from a BSOD.
Blue Screen of Death errors are vital for any Windows operating system despite these frustrations. They play an important role in protecting the computer from accidental damage due to software or hardware malfunctions. In this case, we are talking about K7Sentry.sys Blue Screen crashes experienced by users who use K7 TotalSecurity created by an Indian developer and is relatively popular locally.
Usually, BSODs get fixed as soon as a system reboot is initiated – Windows is typically capable of repairing the damage automatically. However, in more serious cases, the crashes can reoccur, which can be a sign that something is persistently causing the issue, and it needs to be looked at.
K7Sentry.sys is a component of the security suite. Upon installation, a third-party security application makes changes on the core level of Windows so that it can run on the highest permissions possible. Otherwise, it wouldn't be able to find and successfully remove malware from the computer.
