I have been a Zome Alarm user for a few years now. I started with Zone Alarm Pro with web filtering (parental controls) and they discontinued the product; however, they upgraded my license to Zone Alarm Security Suite. About a month ago, I knew my subscription was nearing end, so I decided to try several other products for comparision. My needs are as follows- Good outbound protection behind router that works with home network. It should be eady to use but robust. Antivirus (bundled or separate product)- I already own TrojanHunter Password protection- I want to define allowed programs and lock them down so kids don't install file sharing, etc. Parental Controls- more of a safe guard for my daughter and teenage son Fast User Switching for XP SP2 support since my kids share a computer. Product should not slow down my machines (Win XP SP2 on both, 2GHz 1 GB RAM and 3GHz HT with 1 GB RAM) So here is what I tried- KAV/Kaspersky Antihacker- KAV is great but I was burnt by the istreams tags with excessive disk fragmentation (do a search if you aren't famailiar with this). I was able to resolve this issue with their removal utility and reinstalled KAV by unchecking "use recommeded settings". Antihacker constantly asked for apps permission even after I had allowed them in the ruleset and no there is no password protection. No fast user support, but top notch AV. No parental controls unless I go third party. This is ala carte suite but KAV now offers this a suite that includes antispam. Outpost/KAV- Since Antihacker wasn't to my liking, I substituted it with Outpost Pro 2.5. Excellent combo if you don't need fast user switching support, but web content filtering (parental controls) are very poor because often an undesired web site is not completely blocked allowing graphics and frames of porn sites. The filtering is based on key words that you must define and it often does not work well. Otherwise this was my favorite alternative to ZA. The firewall and AV are top notch IMO but the advertised Outpost plugins are not as good as other products. Trend Micro Internet Security 2005- Very light on resources and priced right. A nice feature is the ability to administer the software on other network PCs from one machine. There were two major show stoppers- the firewall is the worst because you cannot disallow new application access. This is very important because the parental controls only seemed to work with Internet Explorer (all porn slipped right through Firefox and my kids like Firefox). This application offers spyware detection as well but the interface was somewhat clunky. Panda Internet Security- I had used a free offer from Panda apparently one year ago because I got an email from them to renew at a discount so I gave their new suite a try. The product offers everything that I wanted except fast user switching didn't seem to work too well and the biggest show stopper- it slowed down my P4 3Hz with 1GB RAM to a crawl and it wasn't as stable. Popup messages also drove me crazy and this suite and renewals are more expensive than the others. F-Secure Internet Security 2005- Again offered everything I was after, very good AV and nice interface. Parental controls worked great and firewall seemed decent. Also offered a rebadged Lavasoft Adaware as part of the package. I would have purchased this one, but only one show stopper- it dragged my system down to a crawl so I had to uninstall. Comcast Security Manger- Avoid like the plague!!! This is a freebie for Comcast users and includes parental controls, a firewall, and spyware removal, but no AV. The parental controls aren't bad but when you access a bad site, you are given the option to "Add to allowed sites" that requires your Comcast password. If your kids don't know your password this is great, but the also conveniently allow you to reset your password on the same page. The main show stopper- unstable app (blue screens) and clunky interface, although it did not slow down the system. This app has potential but I won't use if even for free. Also hard to uninstall. Norton Internet Security Suite- I did not evaluate this product since I no longer use Norton products due to excessive bloat with previous programs. Zone Alarm Security Suite- Well back to the standby app that hasn't let me down. Comes with CA Vet engine AV that is automatically updated daily and can be updated on demand (maybe not the best but it often wins VB awards and it compliments Trojan Hunter). This is the only app that works very well with fast user switching, has password protection, good parental controls although you cannot allow specific individual sites (only categories), top notch easy to use firewall that can lock apps down, spam guard, but no spyware detection (I use MS Antispyware). Overall this package can't be beat for the price and renewals are only $25 per year that covers firewall, AV, and parental controls. Winner- For me Zone Alarm Security Suite, but your mileage may vary.
