this is not a problem with Rainlendar, but a user acting as if he would be on Windows 95 
Rainlendar skins other than the default skins should not be in %programfiles(x86)%
they should be in %homepath%/.rainlendar2/skins
it's just Windows trying to protecting itself. there are ways to circumvent this, but with your history of regulary occuring malware infections please don't even think about that. (i am serious)
