Hi, I am just running some tests on a friend's machine and avg free found the java byte verify 'trojan'. The system is fully patched SP2 and SP3 so I thought that this vulnerability should have been fixed but maybe I am wrong. I have clared the java cache and the temp internet files and a new scan shows the all clear. However, the C:/windows/system32/shell32.dll file shows as "changed". Is this something that I should be concerned about?
