Negative Positive
Title: Very poor performance
Review: I have two desktops, one running Win XP (Dell Dimension 4600, 2.8 Ghz, one running Win Vista, 2.4 Ghz dual core). I ran the full scan starting at the same time on both using Norton Internet Security 2007. The XP version scanned almost 600,000 items in less than 2 hours. The Vista version is still running after almost 8 hours and has managed only about 233,000 items. The Vista PC is normally a fast machine. It seems that Norton has some work to do to take advantage of dual core technology. Had I known it was going to be this slow (not the first time, either), I'd have opted for ZoneLabs. Zonelabs also found spamware that was not detected by Norton. Granted that it was low-risk, but Norton should have found this kind of stuff as well.I'd probably look more carefully next time before buying a security suite.
Is the review positive or negative?
