When Symantec AntiVirus (SAV) detects a virus or infected file it comes up with a alert dialog box. This dialog box tells you where the file was located (most often your attach folder), what virus the document is infected with and whether or not the clean process worked.
In most cases the clean process does not work and the file is placed in Quarantine. This is good. Because when the file is in Quarantine you can't accidentally send it to other people or infect yourself with the virus.
This how to explains how to delete a file that is in Quarantine.
Important Note: In some cases you may not want to delete an item in Quarantine. Examples would be an important document or your In box (from Eudora). If your In.mbx appears in Quarantine, please contact Computer Support as soon as possible and DO NOT delete this file from Quarantine.
If an important document has been Quarantined you can keep it in Quarantine until your virus definitions are updated. Then you can try to clean these infected files again.
