I know this question appears to have been asked a million times but here goes...

Every time I open Google Chrome I get the error message

Your profile could not be opened correctly...blah blah blah...

I've tried renaming the Default folder in

C:\Users\myUSERNAME\AppData\Local\Google\Chrome\User Data\

I've tried deleting my user in chrome in the Settings page and logging back in again but nothing works. I've also reinstalled Chrome. When I sign in for some reason 3 extensions appear for some unknown reason. These addons weren't installed before this error happened.

I'm using Chrome 33 on Windows 7.

  • What are the three extensions? You might have something messing with your profile.. Feb 24, 2014 at 23:33
  • Google docs, chat undetected, avg safeguard

According to what is written here problem seems to be caused by AVG.

Update 2

  1. Delete this folder C:\Users\<USER>\AppData\Local\Google\Chrome\User Data\Default.
  2. Open Chrome again.

If you have other profiles is preferable to delete them also.

Good luck!

  • I also just tried that with no luck. :(

  • I don't have AVG installed (I did about a year ago) nor can I seem to uninstall the extension since as soon as I sign in again it reinstalls it

Try this Windows 7

Quit Google Chrome. Open Computer. Navigate to: C:\Users{username}\AppData\Local\Google\Chrome\User Data\Default. Delete the file named “Web Data”. Start Google Chrome and the error should be gone.
