|Regardless of which downloads, and where you get them from...|
"Always" use the manual/custom installation option - "never" the automatic...
Using the manual/custom means "you" can see what s pre-checked for installation - and carefully "uncheck" them all. Thus you can elect to install only actual software app/utility you wish to install, and none of the assorted bundled junk, add-ons, search engines/browser changers etc. all of which are usually "helpfully pre-checked for installation - for your convenience..."
Sadly just about every download these days comes with bundle stuff and some is PAI to eradicate... Using teh manual/custom installation path means you can avoid them..
There is also a freebie utility "unchecky" which checks for all those pre-checked boxes too; and unchecks them. But still wise to run the manual/custom route nonetheless. And also use the manual/custom option when you instal it!
