This email was sent to your email address because this is the address that was used when your avast! software was initially registered. If you did not register the product yourself (e.g. somebody else registered on your behalf),
please click here to unsubscribe."


For some reason my email server (GMX) tagged it as suspect.

Do the links redirect to the official avast! site?
If so, maybe your email server just tagged the existence of links in the email body. Just guessing.

Looks like a new batch of them
subject “, try 3 avast security solutions for FREE”
with comma at start

If a legitimate site doesn’t include my registration name(s) in the body or subject line I wouldn’t use a link no matter what the displayed link says.
I wouldn’t even use the unsubscribe link.

If it is a legitimate offer it is probably on their website.
