I have just upgraded to Norton 360 and I tried to get rid of some unwanted stuff at the same time. There seems to have been something loading in the background which now doesn't load. I don't know what I'm missing as I can still do everything I could before but when I reboot I get the following: "Windows cannot open this file: 00348326.rbf". I can't find it on Microsfit site, Symantec say it is not one of theirs. Any ideas?
