Hello, I have been using two programs the last several months which have kept my machine running smoothly and bailed me out when I had windows programs. The first is First Defense ISR(raxco.com). This is easy to install and set up and will create an identical snapshot of your system on the hdd. So, if you have corrupted system files, or your system is suffering from some application you installed which has created havoc, or some other problems, you can shut down and choose to boot into your backup snapshot from the preboot screen and you're back up and running in no time. Now, what about support if you run into a problem? Have you ever tried to contact Symantec? Or perhaps "support" associated with some other application you bought and ended up with those wonderful messages from an auto-responder or mail robot? We all have had those experiences, even after paying good money for the apps we bought in good faith. I have only had one problem with First Defense and the support was really exceptional. Just as good as from Diamondcs. I was contacted promptly and ended up talking to real people on the phone(who paid for the call). I was also contacted by the primary developer who solved my problem. Truly a class act similar to DiamondCs. The other program I'd highly recommend is PerfectDisk. The only Microsoft certified defragger, it's a step above all other defragging apps available today(I've tried several including Diskkeeper) and keeps your system running smoothly by its Smart placement of files feature so that you rarely have to do a full defrag. Both of these programs have been tested and highly rated by various trade magazines(PC World, PC Mag, etc) . Well worth having, Hope someone fiinds these as valuable as I have.
