I have a problem with Zune.exe. 
while I analyze the computer with microsoft security essential (MSE) after about 6 hours (and there are many) I get stuck on Zune.exe. 
not being an expert I searched the internet but nothing. 
I tried to uninstall zune with revo uninstaller and even uninstall a program in the Control Panel. 
at the same time a virus was attacking me and it's called, as MSE said: Virus: VBS / Ramnit.gen! A 
this morning it looked a little as it is self-replicating and also last night but has now stopped. 
I know that you can not be sure just because it has ceased to be reported but unfortunately I do not have an external hard drive on which to save only the many photos saved here.If no saving only those I arranged and reformatting and reinstalling windows 
if you know methods to solve one of the problems I'd be grateful 

this is the screen blocked by 1 hour of MSE:
