Certain applications can access the internet, while others can't. I can still browse the web just fine. Every new installation/reinstallation/update I do ends with that application not being able to access the internet. AIM still works, but it probably won't if I update it. Rhapsody worked before I was forced to upgrade. Now it won't connect. If I install an updated version of Firefox(184.108.40.206 or 220.127.116.11), it won't connect. What's weird is that reinstalling 18.104.22.168 fixes it. Steam won't connect. Neither Windows Sidebar nor Yahoo! Widgets will connect. Ad-Aware won't work, but strangely I don't remember even opening it in over a month, so I doubt it was updated. VONGO still works, but I have a feeling that if I was to reinstall it, it would also cease to work.
Let's go ahead and get this out of the way. This isn't my first day on the job.
I was connected through a router, I bypassed the router and the problem wasn't resolved. With the router connected, I forwarded all of the necessary ports, and that didn't work.
The only firewall I'm running is Windows Firewall. I've added all of the applications to the Exceptions list, with no luck. I've also completely disabled the firewall, and that doesn't work either.
When I restarted into safe mode, everything works, meaning the issue is internal and software related.
I don't know of any application that I've installed recently that would cause this. I don't know if I have some sort of virus that isn't in anti-virus databases yet, or if there's some application that's hidden itself.
I don't have a restore point from before the problem arose.
I've scanned with Windows Defender, and it found nothing.
I'm going nuts. My computer is slowly dying, piece by piece. Somebody help.
Is there some program that can try to access the internet, and then tell me what program blocks it?
