Does Avast! 4.5 Home edition recognize this virus which appeared very recently ?
thanx in advance
Long life to avast! 
Check the VP history list http://www.avast.com/eng/vps_history.html there you can check the lsit of virus that it can detect or make a search in the Antivirus database in the Avast program
To see how the different av vendors call a malware have a look at VGREP
(keep in mind that vgrep always is a bit behind with the names)
