I hope you don't think that waiting a month will protect you. Malicious software can wait to be triggered months or years before anything malicious happens.

It helps. If I were a malware/backdoor author, I have the choice to make it lie idle for a couple months; this would help me get more victims, BUT it gives more time for someone to notice it BEFORE I get any victims at all.

Whereas if it is active immediately, I'm likely to get at least a few victims.
