How to deal with acservice.exe windows process

[RockON!!]

I have recently purchased Logitech webcam to communicate with my sister, who stays overseas, it all works file, we use webcam for most of time, but i noticed that whenever i starts webcam to communicate, it get little slow, that i need to wait for little longer, and therefor when i checked in backend services i found that acservice.exe this dot exe file runs continuously, rest other exe's are familiar to me.
so my simple question is that what is acservice.exe file, does this really slows down your PC.

ArcSoft Connect Service. Background service installed by the ArcSoft software which comes bundled with many PCs or TV cards. If you keep getting ACService.exe errors, you may have registry errors. to stop the acservice being run you may also cut down these service by clicking on Task Manager -> processes. This will also stop these services for particular session.
