Buffer overrun detected!

system · 2007-11-20T15:54:18.000Z

Recently I used “convert” to convert a machine’s file system to NTFS from FAT32.

Since the conversation has completed avast! has stopped working correctly.

It will not uninstall or reinstall, if you try, it produces the following error:

Microsoft Visual C++ Runtime Library
Buffer overrun detected!
Program: C:\Program Files\Alwil Software\Avast4.…
[with information:]
A buffer overrun has been detected which has corrupted the program’s
internal state. The program cannot safely continue execution and must
now be terminated.
[OK]

I am unable to uninstall or reinstall avast!, I have even tried downloading it fresh and deleting all files in my %tmp% dir before running the installer.

What I believe I need is some kind of avast! uninstaller which will remove all references to avast! so I can then reinstall it from fresh. Does such a thing exist? I know Norton has something similar.

Yes there is. You can get it here:

It’s wise to remove any system wide programs (especially those running in realtime) before performing such tasks.
Hope this tool will help though…

Thanks for the tip.

I will test this, and get back to you.

Please wait a bit with the uninstallation, if you didn’t to it already.
We’d like to get some info to look for the problem.

What’s the name of program that generated this error message, is it avast.setup?
Please send file setup.log from avast4\setup folder to my email.
