Avast claiming League is infected?

This guy is having the same problem as I am - http://boards.eune.leagueoflegends.com/en/c/help-support-en/pst4mKzt-avast-saying-lolclientexe-is-malware?show=new

For some odd reason, after the newest update, I've gotten about 6 or so popups from my avast! claiming that League has malware? I'm not sure what's up with it but I'm pretty sure it's a false positive.

Just asking to see if anyone else has had this issue arise or enlighten me as to what's goin on haha
