Parallels saves the day
I have Autocad, Pcad, Designer, Corel, etc running on my PC of crap, and with a RAID array, full mirror backup each night, I touched a trace in PCAD, heard a TING and my system went into a booting loop. No virus, just a registry that had to have it's own hard drive.
After all that backing up, it still took me 4 days to get my system back, then after a week of use, I went to use AutoCad and it wouldn't load. The company told me that a Windows update has some NET program that has been killing them all over the place.
I have been transferring everything over to my MAC PRO 8 core 3gig machine, this was the final straw.
I switched over to it, ran ACAD and did my edit. My only complaint is accessing more processors and a little slowness on the mouse, zoom which was discussed earlier.
Here is my plan:
Load Windows, load only the programs that HAVE to run in Windows, disable the access to the internet completely, only to the network, use the MAC for everything else. With the internet disabled and no browser, you drop your chances of attack and viruses. I have also found that most software companies will transfer your license to the MAC platform for free to $100.00.
I feel free again.
