I have a pretty weird problem. I only noticed it with Google websites yet (Inbox, Drive, Google.com). Some parts of websites don't load, for example some icons are missing from Google Inbox. Some buttons don't work, for example i can't sign in from a different Google Account, because when i click my account picture nothing happens. I'm currently using Opera, however it is same in Chrome, Edge and Firefox. I also tried connecting to another Wi-Fi network. I think it is because of a virus, but my Avast Pro Antivirus cannot find anything.
