Installation went fine through the Avast UI, but it did install Safe Price. Went into Add/Remove Programs and removed Safeprice, but Avast did add a second browser extension to Chrome with that same name as the previous one, only difference was it was titled "Avast Online Security (BETA)" and was loaded alongside the same plugin I had before version number 11.1.0.955.
The BETA version was Version 12.xxxx (Removed it before I wrote down the number for this post)
Not entirely sure if that was safeprice that did that or a bug but w/e. If it was Safeprice's fault, the BETA plugin was not removed from Chrome when I removed the component from Add/Remove -> Change. Had to go into Chrome's extension menu and remove it from there.
Just seems odd Avast would allow two of the same Plugin to run at the same time within a browser...
