Difference between tags virus, malware, trojan, infection,worm

Question

From most used to least used (including related tags):

• virus x 501
  • anti-virus x 453
  • virus-removal x 56
• malware x 256
  • malware-removal x 37
  • malware-detection x 13
  • anti-malware x 11
• trojan x 70
• infection x 8
• worm x 8

Are they really unique? I know that they might be a little bit different by definition, but are they different enough for users that aren't experts on the subject?

Answer 1

I'm of the opinion that for many OP's (who are usually 'basic' users asking for help with an 'technical' (virus/malware type) problem) the exact distinction may be very confusing (and probably unknown).

I still feel the multiple tags should be available - yet users who are not knowledgeable enough to define their explicit problem should be encouraged to use the malware or virus tags.

Questions can then be edited/improved (by the OP or more likely other editors) to make the distinction.

Remember that many original questions may not contain enough information to diagnose the exact cause/'infection' until more in-depth diagnosis steps from comments/questions are taken anyway.
