Trojen gen

I have the trojan virus and when I tried to delete it came up with this:

TROJ MUSSA A non cleanable C:\WINDOWS mssys.exe
TROJ MUSSA A Non cleanable C:\WINDOWS Volume information\

How do I get rid of them? ???

run trend and post the name it gives http;//housecall.trendmicro.com

Already run trend, names given in first message are the names and locations trend gave.

Put 1 in chest how do I get rid of them without harming anything. Please make instructions easy!!! ???

If it’s already in Chest, you can open it (the Chest), select the file and choose “Delete”.
