Can I delete quarantined files in scans?

I'm sorry if I'm in the wrong place, but … When I run Norton, AdAware, or SpyBot they quarantine files that are dangerous to my computer. Should I leave those quarantined files, or can I delete them? I regularly delete the ones in Norton, but not the others. Are they just sucking up space on my hd? Most of them seem to be in the temp internet files, which I empty out a few times a day. Some are cookies, which I also delete often. Thanks, Mandy

Go ahead and remove them.

Thanks, they're gone! Mandy
