Next time it happens have a look here to see if BrightCloud is working as it should: http://www.brightcloud.com/tools/brightcloud-status.php
Webroot, Dublin kindly 'phoned me this morning and having checked that my PC is fully up to date with Webroot's latest update and that Webroot was enabled in all 3 browsers used on my PC, suggested that the cause of the temporary loss of the Green ticks down to Red warnings might well be the result of maintenance,although they would not expect the maintenance to impact on this system for a whole day. However whatever the cause my ticks etc were back in place when I logged in this morning. The possible maintenance trigger does seem a reasonable possibility as the failures occur on or adjoining a weekend as it is fairly common practice for 'house keeping' work to be done by IT engineers over the weekend down time. I was asked if I had ever seen grey dots or circles instead of ticks . I have. This also indicates mainteneance work. So unless the disappearance of the ticks etc is over a longer term than perhaps up to a day, it seems it is not an issue, and hovering the pointer over the items retrieved by the browser does initiate the standard commentry, i.e Trustworthy etc.
Of course Webroot's stanadrd protection is still running so if a user were to hit a malicious website a warning or block would occur within seconds.
Anyway whatever the actual reason, once again Webroot support rode the the rescue at high speed and put my mind at rest, Sservice over & above the call of duty I would say. Long may it continue!!
