Hi,
there exists no trojan with the above name in avast'S database..
do you mean maybe Win32:Trojano-025 [Trj] ?
If so, I believe there where also topics on this one, please use the board search above first
Also tell us which WIN you have, if you have ALL Windowsupdates, and
please try again and post the full path and filename of the infected files
(I didn't get what you mean by System field)
Please be as detailed and exact as possible, or rephrase your question(s) above
you might also want to look here at Info/removal-instructions of earlier trojano-variants:
http://www.virusbtn.com/resources/vgrep/vgrep.cgi?terms=Trojano&product=1Please scan the infected files with onlinescanners from Trendmicro and KAV (see below) so we get some other, more informative virus names.
you will have to pause avast's resident shield to do the onlinescan
