Answer:
Step-by-step explanation:
If you were redirected to another site you didn't want, and you are unsure whether that site is safe or not, you have to pay attention to the domain of that site. If so, try looking and looking at the source code for this page. From the source code you will get a note of any changes made to the original site. And if you can, try comparing the source code of the original with the "investigated" one. Another way to see and investigated it is throughout the structure about this page, like letters, pop ups, some ads you have never seen before and whether this site is asking you some questions or some personal datas.
Another way to beware of this is to install a good anti-virus on your computer or phone. This will make you a little more "safe" about these actions. This apps or programs are important way to be safe about these actions from bad people.
