Symantec is just an awful corporation. They *USED* to have good products some 7-8 years ago. The Live update program updates all related Symantec DLL's and stuff OFTEN. Are these files truly regression tested? Nope. Who tests the software...you guessed it, the general public! Norton A-V 2005 brought my old HP laptop to a crawl. Promptly removed the (to take a word from one of my BITOG brethren from Oz) rubbish. I was surprised to see that it actually removed itself properly. Many times in the past the Live Update or the NAV would refuse to uninstall properly. ick.
Now, they're playing software cop for Microsoft. When did MS ask for their assistance? I'm sure this 'feature' didn't just appear one day, it was developed with MS's knowledge.
I would say "Linux", but if the person is so unsavvy with computers, it may not be worth the headache of teaching them.
Solution: tell them they need to buy another Windows license, or buy another cheap computer that comes with one. Or buy a cheap 17" iMac.
One more reason not to use any Symantec product. It's such a shame that they are slowly but surely ruining the Veritas product line.
