Learning about computers (taking class) and I was exploring my laptop running Windows 8.1 using the System Information window.  Looking in Software Environment at Services, I noticed a Kernal driver with a few of "unknowns"  and "Not Availables."  Google search told me LSM means Linux Security Module. I use Avast virus protection.  Is this part of that or is this part of Windows/Microsoft? Or is it something else since one of the articles I skimmed through mentioned the NSA?

 

Thanks for any info!

In your particular case, LSM = Local Session Manager Service

 

This executable is authored by, and is an integral part of, the Microsoft Windows system.

All viruses are malware but not all malware are viruses and if the malware doesn't self replicate it just isn't a virus.

If you have doubts regarding the origin of a program, you can always check if it has a digital signature:

... Google search told me LSM means Linux Security Module...

You have to be careful when conducting Google searches on the Internet as there is a lot of misinformation out there. When performing search queries, always check multiple sources to confirm the information provided is consistent and essentially the same.

Which is why I came to the experts at Bleeping Computer!  Thanks for the link to learn about checking digital signatures.  Haven't covered that in class yet!
