Top Forums UNIX for Dummies Questions & Answers Trivial Unix Architecture question Post 70947 by Perderabo on Thursday 5th of May 2005 03:33:39 PM

We really need a clarification of terms here. The OP asked about virus attacks. I don't mean to sound pedantic, but the Morris worm was a worm, not a virus. The destinction is important since Unix does enjoy some immunity from classical virus attacks, not malware in general.

On the other hand, language has evolved and "virus" is now often used to mean any malware. I would not be pleased if my virus scanner intentionally ignored a trojan horse. Also some modern malware does not fit comfortably in one of the traditional categories.

So what do we mean by "virus" in this thread?
