Yes, i decided to backup my data last night. And disconnect my laptop from the internet for awhile. Since i read an article that WannaCrypt can also infected without a click or any kind of installation, idk, i still find another articles.
And most of them said WannaCrypt targets all Windows versions that were not patched for MS-17-010, which Microsoft released in March 2017. Even though i updated regularly, it's still scary.
