Hello all. I am unable to open any web browser in Vista. I've had a few things over the past month(the Vista Security 2012 virus) but seemingly managed to clear everything out, and everything has operated fine. However, after a recent reboot(someone else, non-technical, was using the computer at the time, so unfortunately I do not know of any specifics of a crash, antivirus catching anything, etc) now I cannot open any of my web browsers, at least not for any period of time. Usually there's just a slight flash and nothing else, every so often they will open briefly but then close. Firefox I tried safe mode as well at it does the exact same thing. Does anyone have any ideas what this could be/what to check. I reinstalled browsers, no browser processes are running in task manager, etc. I'm really at a loss. Thank you for your time!

First thing I suggest is flushing the DNS Cache "how to" below;

1.Press the Windows key then type in cmd (do not hit enter)
2.In the search results that come up, right click “cmd” and run as administrator, when the screen flashes and asks for permission, accept it.
3.In the command prompt type in ipconfig /flushdns (or right click and paste it to the command prompt) then press Enter.
You should then see a dialog box saying successfully flushed resolver cache, if so you are done post back with an update.

What AV and firewall are you using?
Have you tried IE9?
