What are these processes and should I block them with my firewall?

Question

IEXPLORE.EXE
SVCHOST.EXE
ALG.EXELPFW.EXE
nebios
LSASS.exe

Answer 1

IExplorer is Internet Explorer.

SVCHOST.exe is part of the Windows OS.

LSASS.exe is also part of Windows.

I don't know about the other 2 though. Keep the above three unblocked though.

Answer 2

Other than ALG.EXELPFW.EXE (which is probably a typo on your part) all of these are core windows services. The only one you could possibly block with a firewall is iexplore (internet explorer) on port 80, but that would kill your internet.

Answer 4

You need IEXPLORE.EXE, SVCHOST.EXE.

I'm not sure about the last three.

IEXPLORE.EXE runs your Internet Explorer browser. Leave that alone.

SVCHOST.EXE runs your internet. Leave that alone or you won't be able to get online.
