Upon opening google chrome on android, it suddenly downloaded (unprompted by me) a jpeg, as well as a "seed" file. After scanning both files with the mobile version of kaspersky, i opened the jpeg file and noticed that i knew the picture from somewhere. Upon searching, i found it, along with the seed file in the download folder (from within the chrome app). Both were however said to be downloaded in 2017. In contrast, in my own download folder inside the file manager the files are said to be downloaded today.
Now, what could have caused said (re-)download? Was this simply a bug, or might there be something else wrong with my phone?
