Im not sure what this is but it is blocking me from loading web sites on fire fox and my IE freezes when I open it any help?. HKEY_USERS\S-1-5-21-2875180750-2557437428-1547615657-1007\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_LOCALMACHINE_ LOCKDOWN\iexplore.exe!=w=1

Well that registry key has nothing to do with Firefox. Are you on a stand alone computer at home or on a corporate network?

I'm at home and none of my virus cleaners will get rid of it

Why do you suspect that registry key is the problem?

Some time Firefox will give me a page that says server not found and I think that reg is a virus I can't wipe out in other words I think the reg is the virus messing with Firefox

Nope that reg key is valid, Google it. There must be something else going on.
