Virus fragment 'Piter-708' found in file /snap/core/...

Do you think it's a false positive ?

Hello Antonydb 

"zip bombs", usually take the form of innocent-looking archive files that, when unpacked in order to be scanned, require enormous amounts of time, disk space, or memory.

It is possible that the archive may contain file(s) that have a malicious signature, hence it was detected.

The file has a strange type, and dimension (the HDD on this system is 1 TB, but the file seems to be bigger):

The file is a file type : Link to program crash data (application/x-core)
Link target is : /proc/kcore
Size is : 140,7 TB

Hi Antonydb 

It might be possible that it might have malicious signatures, I would suggest you submit the sample to our Sophos Labs for analysis. 

Hello Antonydb 

This might help regarding the /proc/kcore location -

Since this location is in memory, reboot and see if the detection will persist.
