pup.optional.one click downloader.a - what is this?

8 posts in this topic

MalwareBytes just brought this up. Googled it but it only says how to remove it, which i know how to do as i'll just use MBAM to remove it. I just want to know what it is really & how it got there.

 

My main browser is FireFox, although i do use Chrome at times & IE rarely.

Looks like you accidentally clicked on one of those "Download Now" adverts rather than a download link somewhere.

Yes i did. I thought it was the actual link but it turned out not to be. Following the path this was on 11/10/13 (UK date format). So it's been in there for a short while now.
