After a bout with another antivirus program, which shall remain nameless (but whose initials are B D), I downloaded the trial NOD32 today, and it is beautiful. So far, it works fine....well, as far as I know. It is fast, and doesn't really appear to slow my computer down at all, as did the previous antivirus program. If all goes well after a couple weeks, I'll get the permanent version, and I'll also put it on my mother's computer, which currently has Norton, which works fine, but has slowed the computer to an excruciating crawl. So far, so good!
