computer frozen at desktop

help! i am a computer novice who was impacted by the mess on wednesday. now my computer boots up to the desktop and freezes. nothing works. i have all my christmas data and embroidery designs on this machine and i am desperate to get it working. any ideas? remember, i’m a newbie. i submitted a tech ticket yesterday morning but haven’t heard a peep from them.

They could have received a lot of tickets yesterday… sorry.
Can you boot in SafeMode (repeatedly press F8 while booting)?
Backup your files… and then we can start thinking in what is wrong with your computer?

thanks, i’ll try safe mode, but am not sure what to backup?

ok, i got safe mode but not sure what to do now.

Run a full avast scanning from there.
Also, backup your christmas data and embroidery designs.
