A threat was found that I think is a false alarm

I tried to log into my account at www.diigo.com which is a free storage service that I use frequently but today surprisingly Avast is reporting a trojan.
Please see the log:

Detalles de la infección

URL: http://www.diigo.com/?framerequest
Proceso: file://C:\Program Files (x86)\Internet E…
Infección: html:RedirME-inf [Trj]

I would like to know if this is is false positive and I can open the page or the infection is real.

Thanks
