downloading malebites (ithink) might help
my avast would have detected it though....
Run a full scan with Malwarebytes.
Both scans didn't detect anything :c
It's not malware. You said yes to a toolbar while installing something or visiting a website.I've removed this from people's computers several times.No scanner will find it because it's considered non-harmful software that you willingly approved of.There's a program you need to remove and it will let you change it afterwards.Please pay attention to what you're doing next time.
Uninstall chrome again, look for any chrome folders in ProgramData or AppData, delete them, reboot, re-install
