OK, I've read the Threads about this topic and as retired IT professional,
I have spent hour's upon hour's testing and putting the AntiVirus apps and personal firewall apps through their paces. Symantec, Mcavee, AVG, PC Cillin, Zonealarm,Ect,Ect.
1st) If your using a good router with NAT enabled, you'll have a hardware based firewall along with XP's built in personal firewall turned on,
decent protection without a load on your system resources. and Best of all Free.
if you do not have a router (NOTE: all DSL and Cable modems are in fact a routing device) and most have NAT turned on by default, this protects the ISP also.
They don't want any buga boo's on their servers either. Now if your an unfortunate soul with Dialup,
your ISP usually has some type of protection for you, even the local ISP's do this as a part of their services.
They have them for a reason people. your paying for it, Use it! Besides why would you want to spend your
hard earned bucks on a solution they normally provide.
2nd) As far as Anti Virus Programs, AVAST personal AntiVirus gets my marks, Free Version just
register and they send you a key and allow you to renew forever every year, if your a small business
or a Corporation the Full Pro Program is for you at a reasonable price.
Avast uses very little resources and has a small footprint. It will automatically protect you email clients,
Automatically update itself, Help protect you from bad or infected sites, Skinnable, Alows for a Boot time Scan
of entire system including any Archival files, zips,Arcs,
Rars, Which means before your OS loads,
Incorparates into Explorer to allow file scans at anytime via explorer right click context menu,
Detects infections as soon as you access an infected file.
In My opinion Avast has fewer False positives then AVG or the other popular antivirus apps and
misses less infections then any I've tested.
3rd) Anti Spyware protection. I recommend you install MS Defender as it updates via Windows
updates, Scans daily in the background. It's Free!
Spybot Search and Destroy 1.5 Latest version, Has Browser protection, teatimer active scanner.
You have to check for updates once a week, and download them then Imunize again. this will keep you
well protected. The teatimer will absolutly keep you from all
known bad sites for spyware and adware, This includes alot of so called free online gaming sites
( they watch everything) and the so called free screensaver sites.
( they almost always load apps in the background you don't want) You can pretty much setup
Spybot Search and Destroy to be an automatic deal.
Now if you prefere you can still get Adaware free version but it is limited to manual scans,
I am currently testing Adaware 2007, not free, but does have active
scanning and other features turned on that even the last Adaware version personal SE
does not have. Anyway the Adaware 2007 seems to be doing it's job.
BEWARE!!!! there are alot of So called AntiSpyware and AntiSpamware Apps floating around
on the WEB that are NOT what they claim to be,
They are in FACT! SPYWARE Themselves
I've cleaned a many a system that the Owner stated they were on the web surfing and a pop up
came up and said they were infected and they can download a free
Scan of their system, so they clicked on the link and viola they were now infected or Browser Hijacked.
Stay away from the so called Search sites with the free Tool bars, you simply do Not need them.
just go to Ask.com or Google.com, livesearch.com, then save the
link in your favorites. With IE7 there is a search toolbar already and you can even change your
prefered search site by clicking the drop down from the toolbar(its right
next to the little magnifyer, upper right in the browser.all the browser add ons use resources
and some track your every move, dropping cookies on you like
Rain.
One last Note: Always remember to temporarliy turn off windows restore before scanning for
Virus's or Spyware. If you use a backup solution, you may have backed
up the infection Too! So Clean up make sure your clean and healthy, then Re-enable system restore and do your backup's
Happy Computing to all
