The files below are for your download convenience.  I personally use them all on my small home network and stand alone machines.  They have all been scanned by me but I would recommend you rescan yourself after download to your system.  I very highly recommend you scan ALL Downloads, no matter where you picked them up from before opening them on your computer.
If you are aware of a program that is "indispensable" and that others would find useful in their SOHO, please let me know where it is and I will provide it here if possible, indicating your suggestion to include it.

FREE Zone Alarm version.  Excellent firewall program. 

FREE FTP program.  I find this one extremely easy to use and will perform all functions I need to upload files to this web site.

A FREE Registry Cleaner from the Microsoft support group.  Nice and easy to use.  Has not failed me yet.  Creates a backup file of all date it removes from registry.

Free Adware replacement and I feel it does a better job while offering more control of what is happening.  Adware has apparently dropped support for their Adware program.

FREE AVG Anti Virus software package from Grisoft Software.  Regularly updated and WORKS GREAT!
