information on hosts files and the location can be found here
I use the one from this website.
Also did you try running CCleaner?
I can not load any Google websites or search google via the tool bar. This goes for both FireFox and I.E.7.
I am running XP Pro w/ firewall turned off. I have no other firewall running. I have done a complete spyware scan (twice). I uninstalled FireFox and even turned off Norton (Corp. 10). I have cleared all history, cookies, etc. and still nothing. After trying to load I get "Address not valid" message in I.E.7 and a "connection timed out" message in FireFox. Someone told me my "Hosts" may be messed up but I have no idea how to fix that if it is the case.
As stated, all other web paged load just fine.
Thanks for any help.. It's driving me crazy!!!
