How can i block things from loading on my machine?

try some smart internet filtering app like acespy or website blocker:

Try "MalwareBytes" to start cleaning up your system:

(free version has no "real-time" shield)

You must modify your browsers 'automatic' behavior so it restricts what gets returned, for both security and privacy.

Get Firefox as your default browser & use it for everyday tasks.

The following mods help, but methods ("vectors") are dynamic, and users must stay abreast of daily threats.

FIREFOX: Tools> Options> Privacy> top drop menu set to "Firefox will use custom settings..."> Check 'Accept Cookies from sites'

►Un-Check 'Accept 3rd Party cookies'.

And tick the very top box regarding "Do Not Track".

A good collection of effective add-on's (Official Mozilla) is here:

AdBlock Plus (with 'subscription' added) & "Better Privacy" also helps defray rubbish.

►► At minimum, get the #1 item for malware prevention: "NoScript", which constrains automagically fetching & deployment of potentially tainted assets.

INTERNET EXPLORER does not handle 3rd party assets very well no matter what settings you have (or anything else) and won't give nearly the control as Firefox or Chrome.

It is garbage.

Use to your own detriment.

get the adblock plus and noscript addons for either firefox or chromium. Then you can whitelist which scripts you want to run.

Alternatively you can edit your hosts file so that they go to your own machine.
