Cannot connect to the internet due to a virus / malware of some sort, need help!

I don't really understand, and I'm afraid of messing something up. When I go to type in the new DNS you posted it removes the old ones, and I don't know what that will do.

If it is a DNS problem what does that mean? How do you fix that?

Like I said there appeared to be some form of malware attempting to type in a strange URL at the start, especially in Firefox, and I cannot connect to the internet with any web brower, other than the three webpages I listed, ( Youtube, itslearning and facebook.)

I would also like to point out that the problem is the same wherever I go, at least from both school and at home.

Also, Howard, that link is the one I used. All it tells me is to call them by phone. I cant get the web chat option when I type in my issue.

Really need some help here. Have a project due monday but I'm afraid of doing anything untill I've cleared up what this is, and removed it.

Can anyone please help?

I am using my desktop computer.

I don't know if this is linked to the issue, but the last day this computer's anti virus has started blocking elements every time I log on. I did use my MAC with an ethernet cable linked to this computer a few days ago. Is it possible that the virus has traveled over to this computer as well? Of course, like I said its being blocked by my anti virus here so its not a problem, but I guess this confirms that it is a virus, if it is the same thing.

Still in need of help, I'm at a loss here.

EDIT: Also, John, if you read the post above carefully you'll see that I already said, the issue persists even if I change location.

Ok thank you for the reply.

Nothing is happening when I do that. I turn it off, then on again, hold down ⌘ and r but there is nothing happening.

But I did try putting my safari on private mode, and it seems like that fgot past the problem. I can visit pages it wouldn't let me before. Still wont let me do anything in firefox or chrome, and if I go out of private mode the problem is the same.

Thats what I did but nothing happened. Tried it 3 times.

But since I was able to get online with the private mode, I did get to download an anti virus program. It tells me there is nothing detected yet, though I'm doing a full search through the harddrive, something that its estimating will take 2-3 hours so I dont know if that might help yet.

I appriciate you are trying to help, I really do. At this point I'll take any advice I can get, but your attitude is uncalled for.

The anti virus I am running just found a trojan and it was called api mybrowser something, which was the URL that firefox attempted to send me to. I removed it, and I hope that this was what was causing the issues. As the scan is still going I don't know yet, but I'll come back once its done with an update on wether or not the internet issues have been resolved by removing that piece of malware.

As for the thing you asked me to do, I really did attempt exactly what you told me three times and it did not work. Could you maybe attempt to explain a little more datiled and noob friendly, ( you can probably tell I'm not very used to Macbooks), what it is this method does and what it is going to achiveve? How does it help fix my issue/ identefy it?

Sorry if there is a little bit if spelling mistakes / poor English, and sorry if you find me a little annoying. Like I said, I really do appriciate the help.

Yes I was using the keyboard on the macbook and I was able to boot in safe mode before. It seems the scan is complete now so I can try again as I'm going to restart it. 4th time's the charm.. maybe?

Ok this time it worked. I must simply not have pressed the R key hard enough or something, I have no idea.

So now I was able to do it, and I AM able to load pages that were unavaiable before.
