"Don't be mislead - this product is now FREE - v1.2.6.3"

February 24, 2009  |  By graphicequaliser

 |  Version: MJ Registry Watcher


An excellent FREEWARE alternative to full-blown anti-virus, which uses far less resources and doesn't need signature updates every few hours. Constantly maintained at


User interface could be improved, although it has its appeal in its simplicity and functionality.


There are plenty of positive comments about this product at
This product has saved my bacon on numerous occasions, even on zero-day viruses where other anti-virus products are usually defenceless. If ANYTHING tries to interfere with your Windows system, the changes are instantly undone, and you will be alerted as to whether to allow the changes or not (Accept or Reject). MJ Registry Watcher allows you to configure what you want to protect (files, directories, registry locations and values). You can use wildcarded specifications (???) to protect multiple items in one line. You can use it straight out of the box at default settings, or get your hands dirty and tweak it to your heart's content. You can choose the level of protection from Light through 5 levels to Highest. The default settings are what I have always used and that gives me the protection level which doesn't cause too many alerts, but gives good protection. The alerts can be automatically emailed anywhere you like, and you can quarantine files, directories, and registry keys. The alert sound can be changed to any WAV file you like and there is a free download of Optional Extra Sounds for the Alarms (720K zip file of 33 wavs to set as the alert sound) at
MJRW works under ALL versions of Windows including Vista. To side-step UAC prompts or elevation prompts under Vista, you can use the task scheduler to launch MJRW with administrator rights and set it to run at log on.

Dunno what's wrong with cnet but they won't update the details for this product. As such, their download is over a year out of date, and is for a paid-for version which does not exist any more! Anyway, better to get the absolutely free and bang up-to-date version (currently at http://www.jacobsm.com/mjsoft.htm#rgwtchr

Latest version is now with facilities for combatting viruses like Brontok. Go to http://www.jacobsm.com/mjsoft.htm#rgwtchr to download latest free version.

I still cannot understand why CNET refuse to update this page, but there you go....
