Trojaner-Board - IE öffnet sich jede 10min

Guten Abend zusammen

Ich hab ein Problem und zwar öffnet sich jede 10-15 min. der Internet Explorer das ist erst seit heute so und ich kann mir nicht erklären warum (mein bruder war am Pc:snyper:)

Ich hab die Log file schon hier hijackthis.de/ auswerten lassen , da zeigt es volgendes als schädlich an

C:\Windows\msa.exe äußerst schädlich

Soll ich die Datei jetzt einfach löschen?
Wollte mir einfach Proffesionellen Rat holen bevor ich mir mein Windows verkack.

Hier mal die Logfile
