The first line of defense...For all of your pc(s) and networked devices

Check this out guys!
Think antivirus and software on your desktop and laptop pcs is a good defense against viruses,spyware,ads,malware,hackers...plus taking up all of your cpu time? NO..its actually not

www.untangle.com is the key...This goes on a spare pc of yours(I recomend a athlon 64 or other 64 bit processor)
The deal is. You plug in another network card into the pc your going to use for untangle and plug the modem into one network card and your router into the other. Basically this scans your internet traffic for all the problem causers(including blocking ads and spyware as well as viruses and hackers)and lets you browse and work without worry of id theft,viruses,spyware,hackers,ads,popups! The best thing about it is.........ITS FREE!!!!!! FREE as in FREE you download it,you install it, you use it at no charge forever! and its linux based, has a wonderfull web interface(like your router has) and is simple to configure and install!

I recomend these specs(cheap and good, ive been running them for a year)
celeron 430(35$ at frys and 40$ shipped on newegg)
2gb of ram(20$)
spare hdd(free) or new 40$(can be 40gb even because it will never use all that space)
cd-rom or dvd-rom
case and power supply of your choice!
775 motherboard of your choice(50$ for mine)

Just let me tell you that i havent had a virus or a single piece of spycrap on any of my networked pcs since the install of the untangle gateway! ...I can almost guarantee it! only thing is your antivirus software on ur networked pcs might get a lil lonely because no need to scan or be used!
