HJT logi: Trojan-downloaders

F-securen virusohjelma pompottaa ruutuun muutaman minuutin välein kahta ilmoitusta troijalaisista. Niitä siinä poistellaan mutta sieltähän ne aina tulevat takaisin.

Trojan.downloader.JS.gen tulee C:n juureen tiedistoon 1.VBS
Trojan.downloader.BAT.Ftp.ab tulee jonnekin muualle, muistaakseni C:/WINDOWS/System32
