Trojaner-Board - TR/Dropper.GEN gefunden obwohl nicht geöffnet

Also, ich habe da ein Problem:
Ich wollte ein Spiel wieder auf meinem PC installieren, weil ich hab Win7 raufgepackt und danach lief es nicht mehr. Deshalb wollte ich es neu installieren, nachdem ich es deinstalliert hatte, fiel mir auf das dieses heft mit dem code weg war ... deshalb hab ich gedacht könnte mir ja vielleicht ein keygen weiter helfen.
Schlechte Idee!
Ich hatte einen geladen. Diese WinRar datei habe ich extra prüfen wollen bevor ich mir noch was "weghole". Also "Diese Datei mit AntiVir überprüfen".
Und dann kam halt die Meldung das TR/Dropper.GEN gefunden wurde. Hab ich erstmal in Quarantäne verschoben, und ALLE Dateien (also dieses eine Archiv) sofort danach gelöscht. Papierkorb geleert usw.
-> Ich habe nichts ausgeführt oder geöffnet!!!
Mittlerweile sind nun aber schon 3 Trojaner in der Quarantäne. Alle am selben Abend.
TR/Agentbypass.K.44
TR/Dropper.gen
TR/Dropper.gen

Ich bin jetzt total verwirrt! :confused:
hab mal hijackthis laufen lassen. Ich kopiere das jetz einfach mal hier rein:
