I have tried several times to download CCleaner on to my XP desktop from various download firms. On most occasions the programme seems to download okay but then I can find no trace of it on my Drive C. I have searched using three different search programmes. Programmes but no trace can be found. I use Mozilla Frefox but I gather this app. Is compatible with the latest Moz. Download.

I am running Avira Suite, Ad Aware security, and SpyBot so is this a likely problem, please? Many thanks.
