ADware Infection

So i recently tried to download “Windows movie maker” on my computer, i went to google, searched windows movie maker and clicked the first one that poped up… which apparently was just an adware virus because i am without movie maker, and have a bunch of ads pop up on me when im online, specifically every now and then when i go to click on something, it will not take me to what i click on and will instead open a new tab to a “customer poll survey” screen… annoying as fuck. i have ran adware cleaner and avast free scans, both found things and were fixed, however the infection persists. please someone help me

also cant hurt to note that sometimes my mouse does a double click when i only click once, not sure if this is because of the adware or something else. but thats why this thread was made twice, sorry
