Whether my machine is going for the CPU utilization for the crypto watch service since i have noticed in my machine today that new loop is being present in the machine which i am not aware of before

NAME    MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
loop1     7:1    0  83.8M  1 loop /snap/core/3748
sr0      11:0    1  1024M  0 rom  
loop2     7:2    0  81.3M  1 loop /snap/core/3887
loop0     7:0    0   9.3M  1 loop /snap/cryptowatch/4

What action should be taken from my end ?

Use top to see what your CPU is doing.

Is this a desktop with Snap installed?

[Lakshmana]

@scottalanmiller No I have not installed snap specifically

top output is

root@lakshmana-SVF15212SNW:~# ps -ef | grep "cryptowatch"
root 16854 8092 0 01:33 pts/2 00:00:00 grep --color=auto cryptowatch

Doesn't appear to be using a lot of CPU, whatever it is.

But this things are installed in the machine without knowledge too. How to block the same in future if needed ?

If it was installed, that means something got access to your box. Whether you have malware, downloaded something that should not be there, you've been rooted, etc. we do not know. So very hard to block something if we don't know how it got there. The first question would be to figure out how someone got access to your system to install this in the first place.

Have you checked the logs to see what Snap activity there has been? Any idea when these first appeared?
