Probably because it contains packer code that is utilized by cometer.ib for the purpose of obfuscation. You can make a scan exclusion rule in Kaspersky, just make it the absolute path to the unpack200.exe file. You could also do it to the entire folder if you wanted, but, I'm a paranoid individual & don't like broad rules like that enabled.
As you've found it you can restore it multiple ways, another way is by the 'backup' tab; if that is a setting box you have ticked off (ie make a backup before deletion)

What is the version of RubyMine used?
I'm not at home now so I can't get the specific version but all three applications are at the current stable versions.
