All of my internet browsers are messing up?

[ツǝɯɐu ou [LIGHTS addict.]]

The pages won't load sometimes & sometimes I have to reload the page 10 times for it to finally load. Sometimes Tumblr & YouTube won't work on one browser for a while so I have to use it in a different one. Like YouTube will be stuck on the home page for YouTube & every time I click to like watch a video it just goes back to the home page of YouTube.

So basically all I can explain it is that my web browsers are all messing up all the time. I have Opera, Chrome & Firefox. I don't get whats wrong.

I tried looking into it & it seemed like I had a virus maybe but I did a full scan with Avast in safe mode on my laptop & it showed no signs of infected files.

Whats wrong/what do I do?

Try using Malwarebytes. It will look for malware (parasites) that the antiviruses don't look for.

It doesn't sound like a virus, it sounds more like someone has hacked into your computer through a wormhole. You should get rid of that computer and delete all your accounts and passwords. Get a new computer and don't use your old passwords or logins. Apples dont seem to have those problems.
