Virus Scan

1. After you click the "initialize DB with the selected directory" button, you will be automatically redirected to OSE Anti-Virus™. You will find the to-be-scanned directories on the left side. Next, please select the files types/extensions, update file extensions, and then please first "Initialize DB".

File Functions
Functions:
Backup Items
   This function will make a copy of the selected files to the "quarantine" folder of Anti-Virus:
   site/administrator/components/com_ose_antivirus/quaran/.
Whitelist Items
   If you find a reported file is a false positive, please select the file and whitelist it. Then the file will not be reported in the next scan.
Clean Infected Items
   IF YOUR SERVER ALLOWS THE WRITE PERMISSION FOR THE COMPONENT, your files can be cleaned immediately and a backup file will be created in the
   quarantine folder of the Anti-Virus.
Quarantine Infected Items
   This function is suitable for the condition that the whole file is an infection or the file is uploaded by the hacker, such as shell codes. 
   In this case, you need to remove the whole file. Please use the "Quarantine" function to thoroughly remove the file and at the same time, 
   a backup file will be create in the Anti-Virus quarantine folder.

3. Review reported file before you execute any function.

We provide a new function from Version 3.0 to allow you directly view the files in scanning result. Please click the small "Action" view button after a reported file, and it will redirect you to the OSE File Manager™ to view the file.

View Files

Generally the scanner reports real infected files, but in some cases it will report false positives, because some files may use iframe inside their codes which matches one of the suspicious patterns the scanner is looking for. Therefore sometimes the scanner will alert false positives. Please use the Whitelist function above to whitelist them.

After you confirm that you have whitelisted all false positives and make backup for important files. Tick all infected files and clean them. For shell codes, we recommend you to delete the whole infection files. If you are not sure about the reported infections, please contact us for advice.

4. Whitelisted files and Quarantined files.

You can easily manage the files whitelisted and quarantined in the Whitelist Files and Quarantined Files. You can purge or restore quarantined files in the list.

Quarantined Files

After Cleaning

1. Comparing the Backup Files with the Cleaned Files, you may find the malicious codes inside the file.

Updater

2. If you look at the Cleaned version, the malicious codes were all removed.

Updater

3. If you find that the file was reported as false positives because the codes that have been removed are not malicious codes, please use the "Restore" function in "Quarantined Files" to recover the original files and add the file to the Whitelist for next scan.
