weird messages trying to log into blogger

something weird is going on with my computer.  i have been getting a page pop up when i log into blogger for the last few days.  it's a red screen with a white text box saying 'something's not right here' and a report about one of the blogs that i follow having malware.  i have reported it to blogger and have turned off the bit in preferences about warnings so am not getting it now.  it's only on the computer that i use chrome on.  if i go into ie9 or similar i don't get it.  i am just wondering if anyone else has been getting this page pop up.  i wonder if anyone else uses chrome.  probably not.  i am assuming it's a chrome issue and not blogger.  let me know if you've had it too.
