Apart from what you have been told by the others, I see other things/questions.
Firstly you have multiple copies of that file in the chest so this was a recurring problem for a while. So we may have to do other things.
Though the dates are concatenated I can only see the day not the month or year, so assuming that these are recent then the 16th, 18th and 19th of last month is that correct (or is it from earlier than that) ?
If it is from last month or earlier it looks like the recurrence has stopped and you can scan within the chest and delete if infected as Tech suggests, but it may be worthwhile doing some other scans.
If you haven't already got this software (freeware), download, install, update and run it, preferably in safe mode and report the findings (it should product a log file).
