If you feel wary about a program a little time researching with google
and looking through this group (it is archived if you have a google
account) and you may find more about any particular program, I've not
had a freeware program cause me, personally, any problems for quite
some time and many of them are unsurpasable, if you watch this group
you will find links to reviews and users comments, if you are running
XP you would be well advised to use the system restore at regular
intervals and always before installing a program whether freeeware or
not (windows should make a restore point.. but don't rely on it)
