Okay, read the first post again. I suspect you misunderstand the statement. The point is that there are more additional heroes at the beginning. The three of you mentioned have always existed.
I’ve seen the antivirus (rarely) but havent seen the reinfection things in a long time. Sucks when they always do the infection contests now. Wish they’d give a few of both with contest rewards at least or something. Or with invasion rewards or guild perks.
Yeah they stopped giving those out after a certain contest.
