Hello,

 

I think this is quite an obscure issue - I checked my PCs power plans earlier tonight and found my laptop using a plan called "imfcPowerScheme" that I've never added or seen before.  I haven't used my battery in a while, so I don't know how long this has been present. 

 

I googled it extensively and there's very little information, even on the Microsoft support site.  Some forum posts suggest this is the result of malware, so I ran Malwarebytes Anti-malware (clean), AVG Anti-virus Free (clean) and downloaded the Microsoft Safety Scanner (also clean).  One of the Russian forums I translated suggested that this is some kind of manufacturers plan, but I can't confirm that anywhere.  I can still use other plans, but I'd prefer not to delete the suspect plan before finding out what it is. 

 

Can anyone shed some light on this?  I'm running Win 7 Home Premium 64 bit on a Dell xpsL501x, 4GB RAM and 2.67 GHz i5 processor. 

 

Thanks.

I actually have that page bookmarked :) 

 

I've done the safety scan and it's clean, so all the reply is really recommending is a system restore.  I'm more hoping that someone here might know what that power scheme actually is and how it gets on people's computers.  It's doesn't seem like malware, but you can never be too careful with unauthorised changes.

What does the extra plan settings show when you open it? It's probably some kind of a malware. There is probably a way to rip it out of the registry, but doing that has risks. Typing command powercfg -list will give the GUID string of the plans. Then search that string in the registry and investigate how far the rabbit hole goes.

I think I've pretty much resolved this issue on my PC, but I wanted to post in case anyone else googles it.  There's a guy called 'Podquat' posting on several forums that "imfcPowerScheme" installs in order to prevent sleep/hibernation during video conversion, usually with Xilisoft products.

 

I occasionally use a program called 'Free Cuda Video Converter 6', so I checked it and found that imfcPowerScheme popped up in power options as soon as I began converting a video with the software.  The scheme has been easy enough to delete from power options after every conversion.  It might still be malware, but I suspect it's not.
