It's set to "do not show hidden files and folders" at default.To change this (you'll need admin rights), open explorer >organize>view>click on "show hidden files and folders" and apply.

No problem. Why they make it that way I'll never know.

this has nothing to do with a virus

(it is btw the reason i have been trying to explain several other people for YEARS why you cannot simply copy a game´s folder onto an external HD, then format your built-in HD when you´re experiencing some windows prob and simply paste back your game folder afterwards when you installed a new windows) :

virtually any (or, at least, most) software you install will not only install itself into the appropriate folder, but also into various registry entries hidden deep within the windows system folders

and, sadly, if you choose to uninstall it, it is very much likely that these entries do not get deleted completely.

so, if you REALLY wanna get rid of a software completely (including save games, windows registry entries, registration keys, the folder itself and the like), you may use some tool like regcleaner which makes the software get whiped out from your HD and not only "uninstalled".

and finally:

/irony on

well well .. have a bit more trust in "our" MS guys - they simply want us not to have to worry about such complex things as these ..

/irony off

have a nice day

User folders are intentionally left behind on uninstall by may programs to prevent unintended data loss. Saves and such cannot be stored in program files as that would not work under non-administrator user accounts.

If you want to remove them manually after uninstall, it's as simple as deleting the Ironclad Games folder from (your user folder)/AppData/Local, or the equivalent location under XP.

I'd strongly advise against resorting to third-party uninstall utilities as commented above--they can cause severe damage to your OS install in some cases.
