Malware notifications from source: clients1.google.com

Hello,

Since this morning, I have been getting malware notifications every 5 minutes or so.

Check the screenshot: http://prntscr.com/ebvvjb

Anyone knows how to fix this annoying problem? I have checked my virus chest, but there’s nothing there.

Thanks!
