First some things to remember...

Standard and limited user accounts normally do not have the proper rights to make changes to Windows so always log into a Windows with a user account that has full administrator rights when installing any software including AVG.

Most antispyware, parental control and process monitor types of protection software can block the required changes when installing AVG program, so make certain to disable them when installing or uninstalling AVG.

How to uninstall AVG:
- Download AVG uninstall/cleanup utilty and run it ( if running Vista or Windows 7: remember to right-click on it and choose "Run as Administrator"):

AVG Remover (32 bit & 64 bit version)

If is not possible to download any file (they disappear after download), please remove this file from AVG program folder "C:\Program Files\AVG\AVG8\avgoff2k.dll" (for 64bit systems "C:\Program Files (x86)\AVG\AVG8\avgoff2k.dll") and check the download again.

Please be informed that AVG remover must be finished completely - sometimes stopping of AVG services (for example AvgMfx) takes more time.

- After restart please remove these folders*:

Windows XP/2000
C:\Program Files\AVG or C:\Program files(x86)\AVG (for 64bit OS)
C:\Documents and settings\All users\Application data\AVG8
C:\Documents and settings\All users\Application data\AVG9

Windows Vista/7(Seven)
C:\Program Files\AVG or C:\Program files(x86)\AVG (for 64bit OS)
C:\ProgramData\AVG8
C:\ProgramData\AVG9
C:\Users\<user>\AppData\Roaming\AVG8
C:\Users\<user>\AppData\Roaming\AVG9

( Stop here if not re-installing )

- Then download the latest installation file from this webpage and run it: ( if running Vista or Windows 7: remember to right-click on it and choose "Run as Administrator"):

AVG 8.5.x Installation files are found at http://free.avg.com/ww-en/download-file-ins-afe

AVG 9.0.x Installation files are found at http://free.avg.com/download-file-ins-afg-free

Update AVG when completed, restart your computer and then re-enable any protection software you disabled earlier.

1. On the taskbar, click Start -> (Settings) -> Control Panel -> (Appearance and Personalization) -> Folder options.
2. Click the View tab.
3. Click “Show hidden files and folders” (the name may vary depending on the operating system).
4. Click OK.
