I found some weird policies on my chrome by visiting chrome://policy/ (or about:policy), like ExtensionInstallSources or ExtensionInstallWhitelist. I though it may be from some virus because on other machines with a clean chrome install the policies are empty.
i went to the win 7 registry and removed all the keys/entries that contained the policies names, but when I visit chrome://policy/ they still show up.
I even tried removing the entire \AppData\Local\Google\Chrome\User Data\ folder and the unknown extensions I had disappeared but the policies still show up.
How do I remove them?
