Sony Vaio with W7pro resource monitor shows 48% cpu usage 30 minutes after boot up. Uninstalling is recommended.

Dieses nette kleine Proggi verhindert zuverlässig die Ausführung von Adobe Photoshop Elements und Adobe Premiere Elements. Das Proggi ließ sich erst deinstallieren, nach dem die Datei "LavasoftTcpService64.dll" unter Windows/Sytem32, händisch in "-LavasoftTcpService64.dll" umbenannt war! Danach deinstalliert und siehe da die beiden genannten Programme von Adobe laufen wieder.
