Never happened before. But after upgrading to 18.104.22.1681 I see some sites being added as trusted to the websites list everyday. Right now it is webprot.avira.com, webprot.avira.de and inycs-i.gy1.b.yahoodns.net. If I remove them, they are added back again. Anybody else seen this happen? And how do I prevent this? Before any of you ask me to go to OA forum, let me say this again that I trust the experience of members @wilders the most. Will look elsewhere only if required. Thanks.
