Laptop never ending problems

Hi there,

Ok so i' am the not so proud owner of a samsung laptop and up until recently things were going smoothly - i'm a gamer - I know a lot about pc's and laptops however now i'm stumped.

My laptop has several problems that i need immediate assistance with so please, HELP if you can.

#1 My display driver crashes then recovers ( 3 second duration ) around 10 - 15 times a day; or everytime i have WoW + spotify open and i then open a google chrome page. PLEASE HELP.

#2 Today my laptop decided it was going to spam redirect me to different webpages ( mainly search engines or advertising sites or obviously fake internet security pages ) and give me a pop up spam from the interwebs-hell. PLEASE HELP.

#3 Everytime i load up some form of MP4 file on the internet ( Youtube, Twitch etc ) the video lasts 3 - 6 seconds then i get redirected to > http://www.downlofe.com/GB/index.ph...1ZmJkNjI0OWU5ZjlhNGZkZjVhYzlkNTU2YWI4YWMzZQ== <


These are the 3 problems i'm dealing with, can anyone out there help me ? Im guessing Virus; but im not 100% sure on what the best way to deal with it is.
