Variant:Onex.E

W97M/Onex.E contains a payload that activates based on a random number. In a chance of 1:150 the virus attempts to delete "c:\winnt\system32\ntoskrnl.exe" when an infected document is opened or a document is opened in an infected system. Otherwise it functions like the original W97M/Onex.A.
