So I am having this problem too since few days. After starting my PC, firefox opens with sd-steam.info and redirects to zodiac-game.info after few seconds. Nothing changed and I do not installed anything recently.
There is a regedit entry called sd-steam.info, if I delete it and restart my PC, the pop up is gone but randomly the entry keeps comming back at a point. There is also a taskeng.exe (or something like that) pop up for a sec it is just black and says nothing but it is gone really fast. I think after that the regedit entry is also back.
I tryed multiple malware removing tools already but there are no hits.
I know that the internet is full of this right now but I can not find a working solution. So my questions are:
What is this? Is this damaging my files and causing more problems or just an advertisement?
How can I fix it and remove it completely?
Sorry for not the best english. Please help!
