Critical Win7 file. Ism.exe 32* isn't.
lsm is supposed to reside within the Windows folder. If you find it outside that (e.g.in a user profile), that's something masquerading as the real lsm

I found it in appdata/roaming i deleted it and my computer works fine

It has very bad memory leaks but a way to fix it sort of is by going to task manager and right clicking lsm.exe and change affinity and change it so it only uses 1 so it takes less processing power, All though it will not fix any ram problems it gives, And also DO NOT DELETE IT.
This virus was named after the critical file on Windows, but was placed in AppData instead of System32. I noticed it had been running at startup, but my pc was too fast to be able to see the little line of text when it came by. This is a trojan hidden Bitcoin miner, as wierd as it sounds. GET RID OF IT GOOD LORD. Make sure it's in AppData though. If you delete the System32 one, you're screwed.

It made my processor go 100% constantly, and made my pc very slow.
Had a version in C:\Users\ user \AppData\Roaming that was using 99% cpu from start. Stopped and deleted, no ill effects.
it was using my entire processor 0_0
