Most programmes have no Internet connection!

Hi guys,

Since Friday my laptop has been playing up a lot. It is connected to the Internet and the laptop itself recognises it, but when I try to use Mozilla or IE, the only page that works is Facebook, whereas every other one won't load, as if the Internet were off. Sometimes I can use Google and Wikipedia and every now and then maybe one or two more pages, but then it goes back to saying there is an error loading them as they can't connect to the server.

Skype and Bittorrent seem to be the only two Internet-based applications working, whereas Zune and AVG Antivirus can't connect to the server either. I've run a full scan and a threat was detected, but even after deleting it, the problem is still here.
I've also downloaded Malwarebytes as someone on here had suggested on other occasions, but unfortunately I can't update it for the same reason. I've run a scan with it anyway and, although it found and deleted several threats, it did not solve the issue.

The Internet itself is working as I am using my brother's laptop to ask this question, so there is definitely something wrong with mine.

Any suggestions?

Thanks

Have you tried running malwarebytes? Does all run OK in safe mode

I have and it couldn't be updated as it couldn't connect to the server, so it was 346 days old. I''ve run the scan anyway and it's found 146 threats that I've deleted, but nothing's changed.

I've checked the safe mode and everything was working and I've also run an AVG scan, but I couldn't test the Inthernet connection. I've just restarted the laptop in normal mode but the problem hasn't been solved.

Try safemode with networking....also might see if you can borrow a USB network device and see if that connects, may have a bad ethernet port
