"Object is locked skipped
" or "Access Denied"
notations in a scan are normal. Some files are locked by the operating system or running programs during use for protection, so scanners cannot access them. When the scanner finds such a file, it makes a note and then just skips to the next one. These skipped detections are normally not malware related nor are they infected.
When an anti-virus quarantines a file by moving it into a virus vault (chest), that file is essentially disabled and prevented from causing any harm to your system. The quarantined file is safely held there and no longer a threat
until you take action to delete it. One reason for doing this is to prevent deletion of a crucial file that may have been flagged as a "false positive
". If that is the case, then you can restore the file and add it to the exclusion or ignore list. Doing this also allows you to view and investigate the files while keeping them from harming your computer. Quarantine is just an added safety measure
. When the quarantined file is known to be bad
, you can delete
it at any time.AVG FAQ 1314: I have some files in the AVG Virus Vault. What next?Chapter 9.8
