Please help! Very unresponsive internet browsers

[BathSaltZombie]

Hey guys, need some help

My google chrome has recently started performing very strangely, theres a few things goijg on. First, half of the addresses i type in fail to even come up at all, just says webpage not available, for example this site fails to load. I google search something and it will bring up the results but when i choose a link and try to open it most the time fails to open. Keep in mind i have fast internet, my last speed test was 26ms, 52 up, 5.5 down. the few sites that i CAN open take an unreasonable amount of time to come up. Another thing that is strange is a couple sites that i can manage to load will will weird formatting problems. Like amazon and yahoo, the webpage format is all sorts of messed up and not normal, and pretty unresponsive. This is a new and sudden problem, the first thing that came to mind was some sort of malware messing up my browsers, (this occurs with chrome AND explorer). Ive ran scans with my Nod32, Malwarebytes, and Superantispyware and they come up with no threats. the only things that ive downloaded recently was the last two anti malware programs, thats it. I hardly even use my browser. My Steam is running super slow and only half if the shit on the page is loading, pictures in steam arent loading either, like in library and steam store. Ive really got no idea guys why this is happening, this is a bran new pc that i built and i treat it nicely. Basically all i do is play dota2 online and i can do so with NO lag or hiccups of any kind. But these unresponsive browsers and programs have really got me clueless fellas, please help if anyones got any idea.

It's worth a shot, as @valdyrgramr said.
