I know this thread is pretty old, but it looks to relate directly to my problem. I have Windows 7 (64 bit) and have been using it without issues. I decided to install McAFee last week as I had been running unprotected for a little while. I installed it and everything went fine. Today, I was working on my laptop without issue and then all of a sudden I couldn't connect to the web. I did reboot my modem/router/laptop and it's not issue with modem/router as other devices in house can connect. I also connected thru ethernet cable and still can't get on any website thru any browser (so not wifi issue) So I decided to uninstall McAfee thru Control Panel. Don't know if that was related or coincidence but was trying to troubleshoot. Still can't get on. I am able to ping websites thru CMD line either by IP address or website name, but can't connect via browser. When I run network troubleshooing it says it believes there is a firewall or security policy blocking it. I went in and disabled Windows firewall just to make sure that wasn't it and still no luck.
The only way I get connected is if I boot up in safe mode with networking. I did install Security Essentials while in safemode and ran scan with that and it found nothing.



I feel like somehow it thinks there is a firewall restricting me, but like I said there is no firewall enabled at this point. Hoping someone has some ideas! Thank you



Ive typed all the commands below as stated by someone else and still can't connect to internet.


1) go to start, type "cmd" in the search bar (without quotes), right click it and "run as administrator".
2) type this: "ipconfig /release" (w/o quotes) and press enter.
3) now type: "ipconfig /flushdns" (w/o quotes) and press enter.
4) now: "ipconfig /renew" and press enter.

If that doesn't solve it, do the following

1) type on the CMD window: "netsh winsock reset catalog" and press enter.
2) after done, type: "netsh int ip reset reset.log" and press enter.
