Just ingore. Such erros offten occur, while updating lineage 2 files, so just ignore it.
Even if I can ignore it, the real question is: is it sensible to do so?I was running the game for long time without any problems with the antivirus until today, and I am not so happy going around ignoring virus alerts:
It's not a virus. Add this to exception list, couse anti-virus think it's virus, since this is modded stuff, but it's not really a virus. Just antivirus thinks so... Just add it to exception list and play without any worries.
