I found a virus using avast and the recommended action was to place it in the virus chest, which I did. Do I need to do anything further (ie delete)??
Putting a virus in the Virus chest is for examining the virus, basically most people will leave it in the viruschest for a while (normally a couple of days), and if their/your system functions correctly still, delete the virus from the viruschest.
To be of further help, info such as your OS, virus name, the original filename and location of file/virus needs to be provided.

No, the infected file is quite safe in there. The virus chest allows you to keep viruses away from your operating system in a safe location. It is not possible for the virus to run from the virus chest. ;D
