    Re: Lite anti-virus software

    I'm not aware of any comprehensive comparison of free antivirus products with respect to resource consumption. However, the Norton product is known as one of the more resource-intensive programs, so I suspect that you might have better luck with most other products.

    Although I cannot personally recommend any of the following, most have been mentioned on these boards in the past and you can read about them here and there.
    <UL>Product: avast! 4 Home Edition
    License: "avast! 4 Home Edition is a full-featured antivirus package designed exclusively for home users, non-commercial users. Both of these conditions should be met! ... Institutions (even non-commercial ones) are not allowed to use avast! Home Edition."

    Product: AVG Anti Virus: AVG Free Edition
    License: "AVG Free Edition is available free-of-charge to home users! AVG Free Edition is for private, non-commercial, single home computer use only. Use of AVG Free Edition within any organization or for commercial purposes is strictly prohibited."

    Product: AntiVir Personal Edition Classic
    License: "The private and individual use of the AntiVir Personal Edition is completely free of charge!"

    Product: ClamWin Free Antivirus
    License: "ClamWin is a Free Antivirus for Microsoft Windows 98/Me/2000/XP/2003. It provides a graphical user interface to the Clam AntiVirus engine. ClamWin Free Antivirus uses the GNU General Public License by the Free Software Foundation and is free (as in freedom) software."
    [/list]For extended trials and discounts on commercial AV products, Microsoft has some special offers on this page: Security Software: Downloads and Trials. Personally, I use PC-cillin Internet Security.

    Free firewalls

    For a 9-month-old list of widely recommended firewall software, see <post#=407306>post 407306</post#> - "Software Firewall: Why use it, Where to get it" on this board.

    Does anti-spyware software do a different job from a firewall? Thanks.

    > Does anti-spyware software do a different job from a firewall?

    Yes, definitely. Anti-spyware (AS) is similar in behavior to anti-virus (AV) software. Both AS and AV can (1) scan for unwanted or dangerous executables and associated files; and (2) provide some degree of real-time protection against downloading and/or installation of such files. Firewalls do not do either of those. And neither AV nor AS does what firewalls do.

    To add to Jefferson's comments, you might like to start at Home PC Firewall Guide, and click on the links after "Third line of defense"...

    Re: Free firewalls

    How would you summarise what a firewall does? The netgear router has a firewall. Is this adequate?

    Please refer to the above-linked post on software firewalls for more information on what router-based and software firewalls do and how they differ.

    Re: Free firewalls

    Basically, a firewall is a computer that is placed on the network in between the computers you want protected and all the other computers on the network (for example, the PC in the bedroom vs. all he computers on the internet). Once installed , the firewall filters all network traffic that comes through it. Depending on your needs, it identifies the type of internet traffic and either blocks it, lets it pass unchanged, or redirects it somehow.

    For example, you might want to get email so you would let port 25 (smtp) traffic through. And you might wan to block Usenet access, so you would deny port 119 (NNTP). And you may want to send any requests for your web site to a web hosting company that is running a web server for you, so you would redirect port 80 (http). Most modern firewallls can filter trafffic either in or out. A noteable exception is the biult-in Windows XPsp2 firewall, which only handles inbound traffic.

    In contrast, spyware and virus detectors are simply programs that look at your computer for programs that match the description of certain (very bad) programs that are in their database.

    The firewalls in most of your simple routers tend to be pretty spartan feature and interface wise. You might be better off trying a commercial software firewall first, to keep you protected without having to learn all about TCP-IP networking first !

    Re: Free firewalls

    As a footnote to Jim's comments, on a home network, you do not need to open port 25 inbound in order to receive mail. This would be needed only in the situation, more applicable to a business, where you are running a mail server on site: other mail servers ned to be able to deliver messages to that on-site server inside the firewall. In the home user scenario, you usually are picking up your messages from an outside server, so you only need to allow outbound connections to the relevant ports (e.g., 110 for POP and 25 for SMTP) on those servers. And in most products, you don't need to do anything with port numbers: the firewall software will ask you "is Outlook Express allowed to access the Internet" and you say "sure thing."
