Jun: What do you think about the Norton's Utilities, scan disk, speed disk(defrag) and system check ? I agree with you about Crash guard, I didn't even install it but have had good results with the other programs like Anti Virus. Also why would you not use the e-mail protection in AV 2000 ? To me it seems like a good preventive program. Would like your opinions on the pro's & cons of Utility programs. Thanks Bobby Jun Qian *just my $0.02, with personal experience, I completely vote "not trust" to Norton untility or any similar system protection software. I've found that they only make more troubles than windows itself. I do use Anti virus, but I never turn auto-protection on, I only scan as I wanted it to. one of my friend had one of the "worst" experience with Crash guard software, Crash guard did a very "good" job for him - before any crash could happen, Crash guard always crashes his PC first, so no more win9x crashes, Crash guard already done it.
