Malwarebytes stopped me because of a possible trojan.

Additionally, the description says

Avoid anything that promises a majic fix with a single click. These types of programs usually harm more than they fix because the remove things that shouldn't be removed.

If you are having an issue with your PC, post the problem, and someone can probably give you directions that will not harm your PC.

 

v 20 redirects me to a mycommerce affiliate site,

even when I use the author's link.

You could ask support if older versions are available for download

Sometimes companies pull the old versions because they don't want people to use them.

That version came out in April 2020. I've never used it; I don't believe in using cleaning software. I do it manually so I don't have the program archived. The only thing I was able to find was a GiveAwayoftheDay from march 2021 where v20 Pro was reduced. Of course the link was only good for one day and it had to be installed that day.
