Constant "Infection Blocked" notices

I’ve started getting 6 constant notices of Infection Blocked notices.


Infection blocked!
Avast Filesystem shield has blocked a threat and moved it to the Chest.

Infectin: Win32:OutBrowse-G [PUP]
User: Pegs
Process: /Applications/Dropbox.app/Contents/MacOS/Dropbox109
File: /Users/Pegs/Dropbox/.dropbox.cache/-6486d5b33.tmp


I’m getting 6 popups like this for 6 different files.

I have no idea what to do with them. Appreciate any help.

Hello,
PUP = Potentially Unwanted Program, mostly bundled toolbars/adware in some installers. If you want it, just disable PUPs in settings.
