Hi I am using Prevx 188.8.131.52 with Safe Browsing and realtime protection. Often when Prevx shows the "Authenticating files" little pop in the right hand corner of my desktop Norton Safety Minder blocks access to upload.retento.com. When I did a Google search on it I found out that Prevx is owned by Retento Ltd. Mcafee Siteadvisor lists retento.com as a dangerous site. Could I ask if it is Prevx accessing this site, what it uploads to the site and if it is safe? Thanks.
