Are these programs worth the money? Do they actually make
the computer run faster? Are they dangerous?
Win XP, SP2.
My machine has slowed down a lot. I defrag, chkdsk, Webroot
Spy Sweeper, BitDefender AV. 3GHz, 1 GB ram
In general, NO. There are some good ones, free and pay-for, but chances
of the inexperienced user coming across them are low.
System speed decreases can be caused by many, many things, of which t
hese are only small parts. The registry is seldom if ever the root
cause of a slow performing computer system. If other things are causing
the slow down, straightening out the REgistry will almost NEVER be a fix
because the more important things overshadow it. No, RB in particular
is not worth the money IMO.
You -can- try them, as long as you're certain you have a complete
system and data backup of your drive, but otherwise avoid them. You
should do such a backup ANY time you mess around with the internals of
the OS.
There ARE some pretty decent ones out there though, and if you ask I'm
sure folks would give you a list of some of the better ones. ccleaner
is one that comes to mind; use it all the time on another machine.
However, IMO, your problem is more disk clutter, likely either spyware
or file corruption, spyware being most likely. Get, update and run, to
see if they don't help a fair bit:
= Adaware from lavasoft
= Spybot Search and Destroy
= MS Defender
Read and follow all onscreen dialog boxes or they'll do you no good.
If you don't have a firewall installed, you should. ZoneAlarm still
has an excellent freebie if you look hard enough on their site.
First, do a Disk Cleanup. Click start; programs; accessories; system
tools; disk cleanup. After which, do a disk defrag (same location to
start it). Then run the above scanning tools.
This may sound silly but then do a REstart 3 times in a row. That
optimizes, in a way, the registry structure implementations.
In many cases like this, it's going to be faster but less of a learning
experience to simpy do a backup and clean install and rebuild of your
system.
At a minimum, ALWAYS create a Restore Point before starting ANY of
these suggestions so you can go back to where you started from,
system-wise. Better yet, back up the System State; it's slightly more
inclusive.
