Hello, i have a question regarding avast (free home edition) detecting, renaming, and moving. I recently installed avast and it has detected a trojan in my system. The recommendation was to rename and move the file, so i did just that by clicking the ‘rename and move’ button. My questions is : when the trojan (detected) was renamed and moved does it still pose any problem? What is my next step? Should I have deleted it? Sorry, i am new at this as you can see. thank you for your help. ???
short answer - take option to move malware to the virus chest
long answer will follow as you provide more details as to what has / is happening. I’m not sure myself about the rename option but others may know more. I think avast renames files as they are sent to the chest.
Hi There,
Actually you have did the right things.
But to clear your system from trojan, i am recommended you to delete it.
To make sure whether your system has been cleaned or not, please do avast scan again and give dual protect with MalwareBytes
thank you for your replies … but im still unsure, by renaming and moving the trojan DOES it disable it? should I look for it and delete it? thank you.
i will re-scan and see if it pops up again.
Sorry phoenixdown I’m not sure exact wording of avast alert/warning/detection messages as its been a long while since I got them on my machines and usually was instant reflex to move to virus chest (still is). This is what you seem to have done.
Once in the virus chest, the trojan (or the instance of the trojan that you encountered) can do no harm to your computer. You can delete it in the chest if you want but you don’t have to. I used to delete instances of trojans all the time (to no evil effect), but on better advice I now keep anything I send to the chest for a few weeks just in case. Files that are sent to the chest are quarantined and can no longer affect your computer.
The occasion arises where non-malware or non-dangerous files become sent to the chest for one reason or other (normally false positives), and by keeping them in the chest they can be restored if wanted once their correct status has been ascertained.
also worth noting - the trojan you detected may not be the only instance of the malware. You may still need to fully clean your system. You may want to keep the detections in the chest while the cleaning process is still underway to give you some idea as to the nature of the infection. The instance you have in the chest is so far your only clue as to what kind of infection it is.
thank you MKIS and YANTO for your replies. It was very informative and helpful. 
Hi Phoenix,
No problem there,
And welcome to the forum.
