Threat detected on every youtube movie playing in Google Chrome 64 bit

Avast Free Antivirus / Premium Security
1

Hello,
I have Google chrome 64 bit and when I try to play any movie on Youtube I always get a threat detected warning from Avast. In the Avast’s web page for Threat details it tells something like the following:

Infection blocked URL hxxp://yt.extensionstats.com/v?ms=1&id=sbXk391qXNY&op=1&eid=kekkiaca&url=https%3A//www.youtube.com/watch%3Fv%3DsbXk391qXNY&cb=8896474 Infection URL:Mal

I have Chrome 64 bit ver. 39.0.2171.65 m, Avast 2014.9.0.2021 and virus definition is up to dated and Windows7

I have the same problem. Checked the extensions, cleaned the cache and it’s still like that. Any solution?

3

Did you run a full system scan of Avast and Malwarebytes Antimalware Free Edition?

4

Same here, since yesterday.
Nothing detected with Avast en Malware Antibytes.

Try this https://forum.avast.com/index.php?topic=53253.0

I will inform a malware expert to look into this. It will take some time due to time zones.

The other thing you could do is to re-install google chrome and install the (32-bit version). See if that helps! Also try doing the repair of avast via add/remove.

7

Isn’t this looking more like a false positive than an infected PC or other problem with Chrome or Avast?

It’s something else.
I found this topic on the avast forum: https://forum.avast.com/index.php?topic=160643.msg1152633#msg1152633

I too used the Extension Open SEO Stats(Formerly: PageRank Status).
Disabling that stopped the threat detection in YouTube…
