When looking at my email (& and some other sites) via Firefox my computer takes about 30 seconds to build each page and says at the bottom of the screen 'Looking up ib.adnxs.com'. Using Explorer takes as long but doesn't tell me what it is doing!.
Is this Norton 360 doing this and if so why does it take so long?
I understand that ib.adnxs.com is some sort of malware to do with popups but Norton scans don't suggest that my computer has this.
Thanks
John
