using another wifi like a public wifi at a coffee shop or friends house?
If it's new bring it to the shop and have them fix it...

So just the other day I bought a brand new HP laptop (with Windows 8.1), as my old one is about 3 years old, extremely slow and I was starting to get I/O Device Errors. The first couple of days my new laptop was working fine. Yesterday I transferred some files from my old laptop to my new one, before doing that I ran an antivirus scan with McAfee on my new laptop. I forgot to run one again after transferring the files (my old laptop had no antivirus protection). When I shut down my computer last night Windows did some updates. I don't know if this info is relevant but thought I'd include it anyway.
This morning my wireless internet was working fine on all 5 browsers I use until suddenly most websites stopped working in Chrome, all except one website I was using, until I rebooted my laptop then that website stopped working too. I tried using my other browsers - Firefox, Opera, and IceDragon all won't work, but one website I use works fine in my Waterfox browser. When I try to open Chrome or Opera, which I have several tabs open in, they just completely stop responding (this only happens if I'm connected to the internet). Skype and McAfee also won't open if I'm connected to the internet.
My wireless internet still works perfectly fine on all browsers on my old laptop. What could be causing this problem? I don't have access to the modem as I live in a flat at the back of my landlady's house, and I'd rather not talk to her about this problem unless I have absolutely no other option.
I really hope someone is able to help, as I'm really lost and have no idea how to fix this problem. I thought that the newbie section would be a good place to ask as my computer knowledge is pretty basic. Any help would be really appreciated
