First, I’m an Avast user and not an Avast Team member.
You can’t post links to images - but if you have the image saved on your system, you can use Windows Explorer or other file handling software to Drag and Drop your image into your post. That way it is on the forum web space and everyone doesn’t have to import from an unknown 3rd party site.
Unfortunately you have to install Avast Antivirus to remove Email Protection (former Email Guardian) from your mailbox. Or, ask official support.
How can I remove Email Guard from my email if I don’t have Avast Premium Security installed?
Because the online version of Email Guard is linked to your Avast Account, it will continue to protect your online email accounts even if you uninstall Avast Premium Security. If you wish to disable Email Guard you must reinstall Avast Premium Security. For detailed instructions to remove Email Guard from your email, refer to the following article:
Email Guard - Getting Started
Alternatively, contact Avast Support for assistance.
