It is mostly okay, but here's not much point in having them all running all the time. Just make sure you've got some protection in each of the main areas of intrusion protection, antivirus, pestproofing. I would definitely recommend a good firewall and antivirus program as essential, and then would add some realtime protection - MS AntiSpyware is free and pretty good, though it misses some important things. I also use Trojan Hunter (www.trojanhunter.com), though I've recently switched off its realtime protection and just scan periodically. I like very much Online Armor (www.tallemu.com), because it brings together the features of a number of these programs into one package - but I've recently uninstalled it, because it was doing silly things with Gmail and with these forums (I had to press 'Post' four or five times before it would let things through - each time it came back with a 'timed-out' message); the developer tells me he's working on v.2, which will address these issues. CarolHaynes started a thread on using a Hosts file for safer surfing - search for that, and read the article on the site she points to; it's got some good advice.
