I don’t know why you took it out of the chest as in theory avast would alert again unless you specifically excluded it. The idea of leaving a copy in the chest is you scan that copy to confirm when it is no longer detected. It would have been helpful as requested if you had posted the URL to the VT results.
Doing some research on-line is no substitute to confirmation, using virustotal, so your friend should do as you have confirm and submit to avast for analysis and correction.
Since you don’t mention anything about her detection, file name, malware name and location, I can’t give any detailed advice.
