Hi folks,
Generally, i access my internet without using any proxy servers ie my firefox/IE always has this option unchecked. Then i ran ultra surf this one time (on vista x64) and it worked fine but then once i closed ultra surf i couldn't connect in either browser, inspite of having my original browser settings, wherein no proxy server option was selected.
So currently, i can connect only by using ultra surf and not without it, which's consequently affecting my speed esp for torrents.
I'm certain its not an issue with the settings in my browser, because my torrent client is behaving similarly ( works only when ultrasurf's on ) so if u can point out to something else, i could try that out.
Also, can't be a router issue as it works fine on my other OS.
I generally dont have good luck with forums but hoping u guys can help me out, till then ultrasurf it is.

Sometimes malware installs itself and forces an outbound proxy so it can hijack connections. I would run antivirus and antimalware first. If that isn't the issue then post back and we'll go from there.

Please answer the following questions:

Q.1. Is Ultra Surf a 3rd party software which u use to connect to internet?

Q.2. R u using an ADSL Modem+Router provided by the ISP?

Browser settings is not an issue ,but do make sure that ur browser settings donot change as soon as u close ultra surf.

1. No, i used ultra surf only as a one off case. Normally i can connect without any 3rd party software.
2 Yes I am, its an ADSL router provided by the ISP.

Yes i understand that browser settings do not change but i suspect that there's a process running which bypasses the normal route when i try to connect(without ultrasurf), probably because, prior to using ultrasurf i tried using some public proxy server websites which could directly do what ultrasurf was doing, so this could have installed some malware perhaps. Can you suggest a specific malware detection software which can detect such a thing. I've run a full scan (kaspersky 2009) and the problem still persists

www.pandasoftware.com has an online scanner. You can also try "Spybot - Search & Destroy" and Malware Bytes has a product. I would run them all.

Even after running these scans the problem still persists.None of the scans detected any malware of any kind so i'm beginning to doubt if its a security issue. i think its a problem with my network setup somewhere. is there a master setting of some sort where i can set the default route in vista x64? Or any other suggestions

route add default gw x.x.x.x or route add default x.x.x.x in the command prompt will set your route.

The gateway was already set in my router which's why it worked in the other OS. The problem however disappeared after i upgraded my OS to a Win 7 test build.
Thanks for the help.

That is odd but i'm glad it is working now.

Please mark this thread as solved as you have found a solution (albeit a workaround) and good luck!

Well, I got the same problem, but being a newbie I don't know what to do to solve it. It also affects my girlfriends computer, who use the same router.

Can anywone walk through tje steps please?
