I have a new Dell laptop with Windows 7 (64-bit).  Normally I install AVG but I thought I'd give Avast a try (the free version).  The install went fine, but when I run a manual quick scan it always hangs.  The current file shows "SVC: .NET CLR Networking".  
Any ideas anyone?
My version is 5.0.594.

Rob.

If possible, do the following, please (should work on Win Vista and Win7):
- disable avast! self-defense (avast! settings / troubleshooting)
- start the scan again and wait until it gets frozen
- open Task Manager
- righclick on AvastSvc.exe
- choose "Create dump file"

Then navigate to the location of the dump file (it's shown when it's done - you can copy&paste the path) and upload it to ftp://ftp.avast.com/incoming.
Thanks.

your guide got to the message "writing to file" when dumping and it hangs there, nothing seemed to happen.

That is pretty strange...
What if you stop all avast! resident shields before starting the scan (that is about to freeze)?
(Btw, did you give it a while before concluding it hanged? Any hard disk activity indicating it might still be writing?)

about 30 minutes.

i am pasting the dump file now to ftp://ftp.avast.com/incoming i didnt see a upload button. so at least it worked with the shields disabled.

it should be finished in about 19 minutes according to the file copying.

Yes, thanks a lot.
A dialog box seems to be displayed by the service (which doesn't have access to your desktop, so it's not visible)... and probably waiting for some input. That's why the scan is frozen.

If I might ask for one more thing (which is actually the cause of the problem) - you have a shortcut "Valg av nettleser" on your desktop (probably added by a Windows update recently). Could you please also upload this shortcut to the FTP? (I mean the shortcut itself, which is a .lnk file)

Thanks!

Thanks for the file. Unfortunatelly, the problem doesn't reproduce even with that... (sounds like a bug in Windows anyway... second in two days, looks like I'm really "lucky").

If I prepare a small test tool, do you think you could run it on your machine - to see of any message appears?
Thanks.

You can certainly delete the dump.
Please keep the link on desktop for now - that's what the tool will try to check.
I'll be back soon.

OK, here is the tool: http://public.avast.com/~glucksmann/LinkCheck.exe
Just download it, run it from the command-line console and watch if a warning dialog (about the target of the link missing) appears. If it does, please note what is printed in the console at that moment (there are 5 attempts to do something, so it theoretically might appear 5 times; hopefully not).

Now I bet it won't appear at all... which is the worst thing, of course, as it doesn't really reveal anything.
(sorry, updated the file just know - used a wrong filename inside).
