AVG Antivirus detect Labview 7.1.1 builded executable as trojan

[Maxim]

This morning (13-May-2010) after AVG updated Virus definition all application compiled with Labview 7.1.1 were detected as infected by a trojan : Downloader.Agent2.WTI and automatically moved to vault or deleted.

After checking the PC (without finding any trojan) with different Antivirus I concluded that this was a fake recognition of AVG. This was confirmed by several customers worldwide (using our software compiled with LV 7.1.1) reporting of the same exact problem. The possibility for the Trojan to have simultaneosly infected different PCs in different locations is very rare. 

Anyway AVG caused some problems : in the best case the EXE were just moved into the vault (so after disabling AVG Resident Shield and recovering all went ok) but in the worst case AVG deleted the "infected" files causing the need for a new installation. 

Hope this can help someone to prevent the same problem !

At least it called LabVIEW a TROJAN.  Much better than a worm IMHO.

Thanks for the heads up.  I use AVG at home.

We did contact AVG and had the following reply from Support -

Since receiving that message there have been no further reports of infected files.

I have had the same problem with McAfee.  I was copying developer DVD's to the hard drive and some of the files were tagged as infected and removed.  And when I tried to send them a sample of the file they said the file was too big.

Go figure??
