You have done the right thing, ‘first do no harm’ don’t delete, send virus to the chest and investigate.
There is no rush to delete anything from the chest, a protected area where it can do no harm. Anything that you send to the chest you should leave there for a few weeks. If after that time you have suffered no adverse effects from moving these to the chest, scan them again (inside the chest) and if they are still detected as viruses, delete them.
It would have been good if you gave a couple of the reasons why a file couldn’t be moved to the chest, commonly if this happens and you are able to move/rename it was because the file size exceeded the settings for the chest. You can adjust these from the avast Program Settings (right click the avast ‘a’ icon), Chest and adjust the sizes as required.
Files moved and renamed will be in the C:\Program Files\Alwil Software\Avast4\DATA\moved folder.
Before sending anything to VT to Jotti you should give some information about the detections and we can advise.
What is the infected file name, where was it found e.g. (C:\windows\system32\infected-file-name.xxx) ?
Check the avast! Log Viewer (right click the avast ‘a’ icon), Warning section, this contains information on all avast detections.
For the most part there is little requirement for DIY as you call it in avast, VT and Jotti are usually used if you have a suspicion that the detection might not be good and is the exception rather than the rule.
