Seen on the Kitz forum, a scam email puporting to come from Microsoft with a link to Windows 10 upgrade that contains ransomeware. Link here
Have just read the article about the scam on the BT.com homepage.
For existing Windows 10 users, there's a potential problem if you use a laptop with touchpad. It's system bug (there's problem with the touchpad driver).
Every time you shut down, or reboot, the touchpad and mouse settings revert to default.
Unfortunately, "default" settings are troublesome - namely the "tap" feature, where before you know it you have opened a link by just hovering over it.
You can reset the touchpad settings each time you reboot, but it's better to use a mouse. This reduces the risk of inadvertently opening something up, but the risk is still there, as the touchpad in it's present driver state, is still active.
