Avast blocking site popup -- cedexis?

I keep getting a pop up from Avast every time I refresh tumblr (and only tumblr) that reads: Avast has blocked access to https://level3.cedexis-test.com/ because the service certificate has been revoked.

How do I make this stop/what does this even mean? I scanned my computer for viruses and malware, but there’s nothing.

In short, Avast didn’t block malware and this is not issue with malware. Website you linked uses expired (not valid) SSL certificate and Avast blocked it due security reasons. If not blocked by Avast it would be blocked by your browser. It is up to website owner to extend its SSL sertificate validity period.

Hi Sass Drake,

Not exactly so, the certificate, see results from this scan: https://cryptoreport.websecurity.symantec.com/checker/
is installed correctly with a GoDaddy Root Certificate Authority G2.

My adblocker, uBlock, blocks it 'though while it is listed at Blockzilla.
