I am a new user of Total Security Multidevice 2017 as of today. I registered on Central, downloaded and installed and everything seemed ok. It prompted me to remove my previous security program and restart. It then downloaded itself (again) and started the install. I then updated the software (and I presume the virus definitions) and it gave a little flag to say a restart was needed. I duly complied. After it went through the reboot, my login screen appeared as usual but when I logged in, all I got was a black screen and only a mouse pointer visible. I did a bit of a search and somewhere there was a post about delays but not in this case - nothing happened. Although TSM2017 did not complain, I remembered that there was a firewall installed. I managed to boot into safe mode (which also seems to be a bit hit and miss) but you cannot uninstall in safe mode. I have no idea what to do now, any advice? I am on Windows 10.
