Remember to back up your souvenir pictures after your holidays. And take the opportunity to also check your remaining data are backed up properly, too.
Holiday time is photo time. So that your valuable souvenir snaps aren't lost or destroyed by malware, you should create a back-up copy of your pictures as soon as possible. This is good opportunity to also check that all the other data on your devices are up to date, and then back them up, too.
Simultaneously, you should install any updates for your operating system and all your programs as well - especially if you haven’t used your computer or tablet for several weeks.
