You can use the avgscan.exe file for these purposes. It has to be run with parameters, so if you want to scan your C:\ drive, you have to run this command-line scan in the following format: avgscan.exe C: /parameters.

If you want to scan a specific file/directory, you have to replace the C: path by specific path. The list of possible parameter you can get by the avgscan.exe /? command.

Yes, it is highly recommended. You can use an older version of the Rescue disk to restore system parts of your PC but for removing/healing viruses you need the Rescue disk with latest virus database. It isn't possible to use Rescue disk for removing/healing viruses on NTFS disks, therefore the creating of Rescue disk isn't available on operating systems running of NTFS.

Note: The Rescue Disk function is only intended for OS Windows 9x/Me.

Within the 3rd party program scanning options choose avgw.exe with /SE parameter (avgw.exe /SE) as the internal antivirus scanner. Avgw.exe file is located in the AVGFree Edition directory – usually C:\Program Files\Grisoft\AVG Free directory on your hard drive. If you would like to use AVG Free Edition for checking files in WinZip archived files, it is necessary to use the following configuration parameters within WinZip, as shown below:

WinZip->Options->Configuration->Program Locations
Scan program:
Program Files\Grisoft\AVG Free\avgw.exe

Parameters:
/SE %d

AVG Free Edition needs these system libraries to work properly:

Libraries which are not part of the installation:

• OLE32.DLL (any version) - you can see the notice with exact link where you can download it

Libraries installed into the system if they do not exist or if they are older:

• MSVCRT.DLL (version 6.0.8797.0)
• MSVCP60.DLL (version 6.0.8972.0)

Libraries installed into the AVG Free Edition program folder if they are not found in the system:

• MFC42.DLL (version 6.0.8665.0)
• PSAPI.DLL (version 5.0.2134.1)
• SHFOLDER.DLL (any version, 6.0.2600.0 version is installed)
• DBGHELP.DLL (version 5.0.2195.1)

After updating Windows XP SP2 (update KB925902) there can be problems launching the AVG Control Center. The displayed error message can be related to one of the following system files: hhctrl.ocx, user32.dll, shell32.dll. More information about this issue can be found here. The solution is to install the patch from Microsoft, which can be downloaded here. If the problem persists, please try to uninstall Brico pack Vista inspirat 1.1, or another used graphic user interface upgrade.

There may be a problem with some of the AVG Control Center components after the last AVG update. This problem appears when a very old version is updated or previous version wasn't updated correctly. The error messages may be related to:

• Virus Base component (incorrect state)
• Shell Extension (not installed)
• Resident Shield (not loaded or installed)

The solution is to do a Repair installation of your AVG using the latest
AVG Free 7.5 installation file. This process is described in details in our FAQ 625

Examples of possible error states:

• Error: Resident Shield is not loaded or installed
• Internal virus base: "It is not possible to check the state of this component, connection failed." or "Component is installed properly, however the control failed with error code: 0x81000002"
• AVG Shell Extension: AVG is not integrated in the Microsoft Windows Explorer.
• Operating system reboots itself.
• Virus EXCEPTION found on Avgcore.dll, avgcc.exe files
