If you notice unusual or unauthorized activity in your Web History, please change your Google Account password. This should prevent someone else from accessing your account again in the future.
If you notice unusual activity in your Web History after you've changed your password, it's possible that you didn't sign out after you last accessed your account from a public computer. In this case, your Google Account may be open to anyone who uses that computer. If feasible, we suggest that you return to that computer and make sure that you're signed out.
It's also possible that someone has accessed your computer. Here are some tips that may help you solve this problem:
- Install Google Pack and use Spyware Doctor to remove Keyloggers or Spyware from your computer.
- Sign out from your account, change your password, and clear your cache and cookies.
