Ken, I've looked at the thread and AVG on my PC is reporting the same virus as Marian has problems with. I'm using AVG version 9.0.791, database version 271.1.1/2756 (19th March 2010). What is a 4.48 file? Is this the version of PtoE that created the file that you used for testing? The files that are giving me problems are from several versions of PtoE - some going back 3 or 4 years - including version 6 which is the only one I now have on my PC. Pat.
