It's a problem that FileHippo's Update Checker only speaks English and therefor installs English programs by default. It can make a terrific mess in peoples PCs if they don't realise this before using it. F-Secure's (free) Health Check and Secunia PSI have a very clear advantage there as they offer international services. Both are available as online scanners and Secunia also comes in a download-able software version.
F-Secure's Health Check is often forgotten but it's a really fine scanner. I think perhaps it's confused with F-Secures free online anti-malware scanner. Here's the link for their Health Check:
