Since the 29//2006 virus update (0613-1), Avast keeps finding the “Win32:Webdor-G [Trj]” trojan in my Opera (*.adr) bookmarks, even in years old bookmark- backups. What virus-string has been added to this update, so that I can change the name of the culprit bookmark? Seems a false, yet annoying alarm. ???
Ha die Maarten,
You are infected with agobot aka webdoor-g trojan, look here:

“Verwijderingsinstructies via dezelfde link als boven, succes met het weghalen van dit trojaans paard en welkom op ons forum”
(In dutch: removal instructions through above mentioned link, success on cleansing this trojan horse from your comp, welcome to our forum).

Thanks Polonus, It’s great to have such fast solution!

… however, no infection was found by the F-Bot utility; not in memory, not on the hard drives.
When I remove all my old bookmarks and start afresh, AVast has no problem, but even checking the old archived bookmark files, the siren starts! So I am back to my initial assumption that the latest virus-database has introduced a search for some character-string, which can also be found somewhere among my bookmarks.
The latest update of the Avast virus=database solved it all. Thank you, team!
