Partition Magic is a good product, originally from PowerQuest which is the
version I have. It is not like NIS or the AV. PM is not memory resident.
It is invoked to do a specific job only. There is a lower cost alternative
from Terabyte Unlimited called BootIt Next Generation (BING). It has a 30
day free trial, full featured version. I have not used it but many of the
folks in here recommend it.
Bundled programs are as much an issue of marketing agreement between the OEM
and the partner. It does not mean it's the best for your system. For
anti-virus there is Avast (free version, which is what I use), AVG (free),
Computer Associates Etrust (low cost). For firewall there is Zone Alarm
which has a free version, and Sunbelt's Kerio Personal Firewall (low cost,
which is what I use). For spyware, adware and other such there is Spybot
S&D, Adaware, HijackThis, Spyware Blaster and Windows Defender. The other
functions in Norton can be accomplished by tools within XP (or by free
downloads) and/or don't add much value. For example XP's defrag works just
fine. Registry cleaners are unnecessary and can be dangerous.
You may have spent money on some products but what is the cost to you for
the time and grief spent on trying to fix things when they cause problems?
One thing you will discover, if you carefully choose the apps, is the number
of headaches goes down significantly and system stability increases
immensely.
