Auf jeden Fall wird man über Systemänderungen informiert, besser als wenn man nur kostenlose Firewall & Antiviren-Software einsetzt

Das ist bei mir der Win-Defender - update nehme ich an
Windows Defender, OS-Bestandteil Vista, unter XP und frühere Virus/Spyware wenn Defender nicht manuell installiert wurde.

Calls itself "Windows Defender Command Line Utility" is m$ signed and resides in the defender directory. I have no idea though why it is running all the time, never started it, and only recently it was there (maybe after latest vista service pack?)
Microsoft Security Essentials

Verbindet sich bei mir alle paar Minuten ins Internet. Keine Ahnung warum. Dabei werden keine Updates überprüft. Wird MmN nicht bzw nur temporär benötigt, da der Service Win Defender bzw MS Security Essentials auch ohne ihn laufen.
