Yes, a program always uses some resources... On my old laptop (Celeron 700 with 256 mb ram running XP) zonealarm makes the startup slower. After, it is not really noticeable.xenaprincess said:if I install a firewall...will this use more resources than I am already using
What is your processor and how many mb of ram do you have?
System information tells me 74% system resources free, but of course that changes drastically depending on what programs I have opened. As of now...I try not to have anything running in the background.
