Related to reply # 3 in https://www.wilderssecurity.com/threads/nod32-not-updating-virus-database-18-sept-2014.368331/ I needed to use PLAIN tags. I wanted to highlight the lines which were different in the two updates (the old one and the new one). [PLAIN ][b ] ... [/b ][/PLAIN ] That didn't work. That was probably to be expected. Example: [b]Virus signature database: 10438 (20140918)[/b] Would doing it the other way around work? [b ][PLAIN ] ... [/PLAIN ][/b ] Virus signature database: 10438 (20140918) Yes, that works. But then I should have been using the Plain tags in several lines there, and I must admit that I was too lazy for that. So I decided to forget the highlight tags and put the whole post between Plain tags.
