Yup, I came across this crap the other day and did a double take. It is really peeing people off. Avast have shot themselves in the foot with this.
In the last week I have been asked to remove avast from @ 7 laptops and a couple of PC's and replace the AV with another product because people had done a default install and not realised they were going to get Google products added.
Come on avast , toolbars for heavens sakes
?? Very, very stupid move, nobody wants them on their systems.
