2 or 3 false positives is typical.

Which version caused a warning?

All A.V. are rubbish IMO, I haven't used active AV for well over a decade because they cause bigger head-aches than they prevent if you know how to avoid viruses... IE, don't download and install random dodgy stuff from dodgy sites (use old trusted sites and check downloads at virus-total).

Idle master does not give you cards.

1) Idle master looks at your badge page to see which games have card drops remaining.
2) Idle Master tells Steam that the game(s) is playing.
3) When the game is played for long enough, Steam gives you a card.

引用自 Mr.lagaso：

HELP pls. I started a steam account in idlemaster that I didn't want, and when I click disconnect and then connect to start with another steam account, it automatically starts the account that I don't want.

You don't have to log out, see screenshot above.

Rephrasing

Idle-master will idle up to 30 games because Steam will ignore any more games.

Size of whitelist is irrelevant, put as many games as you want on a white-list, Idle-master will only idle 30 games, once all card drops have dropped for a game Idle Master will will idle other games.
