CCleaner download request redirected to malware site?

Trying to download latest CCleaner 5 minutes ago I was redirected to download-now and that website was intercepted by my antivirus software AVIRA with warning:

"downloadnow-1.com

"This is a malware website

"Malware websites infect your device and can include viruses, worms, spyware and trojans.

Can you confirm that downloadnow-1.com is your official download website?

And if so, why is it blacklisted?

Thanks

Please do downloads from here

Where were you originally trying to download it from?

Hi Hazelnut

Updated successfully following your instructions - thanks.

I was responding yesterday to what appeared to be a standard update invitation pushed to my system by Piriform at startup (tagged as from www.piriform.com/ccleaner/download?upgrade).

Message received yesterday invited me to get the latest free CCleaner update by clicking on a link (embedded in the invitation):

Download.com

(sorry I didn't save the full html)

When this hyperlink was clicked, it redirected itself to downloadnow-1.com, which was intercepted by antivirus software as reported earlier.
