Been getting little blue box that pops up just above date and time?

Most of the time it pops up(slides up behind the task bar into place right above the date and time) it asks me to update VLC player, with a few times where it asked me to update Libre office, I have the option to don't show again or to update, but I usually click the little X at the top right corner of the box to get rid of it, so this time I finally clicked update and it disappeared and a red norton warning popped up, AdWare.Eorezo blocked, computer is safe, have done a full system scan plus power eraser and have found nothing and box still pops

To give detail the Blue box has a whiteish blue border and the VLC logo/icon close to the top right corner.

Finally found out what the box is, didn't know it but when I installed Alcohol 52% it automatically installed Smart File Advisor. Just used Revo Uninstaller, and uninstalled both Alcohol 52% and Smart File Advisor and the blue box is no longer appearing.
