Takes up lots of CPU resources, hard drive activity. Lots of network activity to another PC on my internal network using SMB protocol. Tree Connect AndX Request, The destination reported an Error: STATUS_BAD_NETWORK_NAME.. Saw activity with Ethereal / Wireshark. End Process Tree it all goes away.
It opened up a popup window that could not be closed, had to do a restart to get rid of it. It also seems to be a hidden file, doesn't show up on searches or in the subfolders I think it should be in.

Works the HD to death and consumes 9% of my 2.67 MHz i7 processor's time while it is running. It is massively wasteful of time and wear on HD's. I don't use either Cyberlink's Power2go or HP's MediaSmart Music/Photo/Video SW so I deleted them both.
The program maybe causes minimize in fullscreen windowd programs such as games,ect,

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem.
