Trojaner-Board - Trojaner gefunden

Hallo, habe einen rechner geschenkt bekommen und der ist glaub nicht ganz sauber ;-)
Antivir hat folgenden Trojaner gefunden
C:\WINDOWS\system32\TFTP172
[FUND] Ist das Trojanische Pferd TR/Crypt.FSPM.Gen
[INFO] Die Datei wurde gelöscht.
Aber komischerweise macht Antivir keine updates (auch nach diversen neuinstallationen)
Hat hier einer eine Idee?

Vielen Dank im Voraus
