Dot Net compatibility?

Viruses and worms
1

Hi All,

After installing and updating Avast (free) 4.0.235 VPS-0307-8, it detects the W32.ALCAUL.A4 worm everytime a .Net Framework program executes. Turning off Avast, the program executes fine, otherwise it crashes.

Browsing that .Net program folder, as well as the whole disk C:, Avast does not detect any virus nor worm.

I guess the .Net Framework is confusing Avast, because other antivirus never interfered with such program before.

Any ideas?

Hmmm, very interesting…
What filename, exactly, does avast give you when reporting the virus?
Is it a file from the .NET framework, or the EXE itself?

And what OS are you using?

Thanks,

My OS is WinXP Prof SP1 with .Net Framework SP1. The program is an independent utility for using as an add-on to MS Flight Simulator. This utility executable needs the .Net Framework environment, as it was written in VB.Net. You can find it in the file “editvp20.zip” searching Google (or I can send it to you).

No need to install it. Just explode the files in a folder and execute Editvoicepack.exe with Avast ON to receive the alarm. You won’t need FlightSim to use it, as it is only a test.

I forgot to mention the file name detected by Avast:

It is a different DLL file each time the program runs, inside the folder c:\Documents and Settings\myname\Local Settings\Temp\xxxxxxxxx.DLL

Indeed an interesting problem.

I managed to simulate it and back up the file - and I passed it to the virus guys for further inspection…
I’ll keep you informed…

Thanks,

Oh yes, you got us here. It was indeed a false positive. Big thanks for pointing this out!!! :slight_smile:

It shouldn’t be shouting anymore starting with the next virus database update, possiblity due tomorrow.

Thanks again,
