I'm using Avira also... though it's known to cause a lot of false positives.
Can you take a screenshot of the warning?
Does https://elliquiy.com work?
If you open up a command prompt, and run
What IP address do you get?
I can take a screenshot however because of currently still staying with family I only have my laptop, which has no photo program which I can paste the screenshot into. However I can tell you it pops up with this in the warning box saying its a HEUR/HTML.Malware - Heuristic
Ran the command prompt and the ISP which came up was 174-34-158-178
I decided to then type in https://elliquiy.com
myself instead of using the one in my favourites and this time no virus warning has popped up on that page or any I have clicked on within the site. I am keeping my fingers crossed that simple suggestion from you has solved the issue...will let you know for certain either way after a clicking a few more posts and such.
