Avast anti-virus is now whitelisting QSPICE

Hi folks,

I posted this in the “malware” thread, but wanted to give it its own topic for visibility.

If you are using Avast anti-virus and ran into problems installing QSPICE, please try again. Avast has now whitelisted several key QSPICE files, including the “AcmeSemi.DLL” sample model.

So, I’d love to hear about successful installs, and I’d also like to know if Avast still has issues; I can submit more files for whitelisting if needed.

Finally, Avast and AVG are the same company. I suspect they share a whitelist, so if you were running into problems with AVG, a test install would be useful information for us.



HP antivirus report Win32.Trojan.Generic…InstallQSpice.exe is malicious.

Thanks for the alert.

Avast just blocked it as a threat on my laptop: “We’ve safely aborted connection on getqspice.com because it was infected with URL:Blacklist”.

I disabled Avast from blocking for 10 minutes, and was able to successfully download and install it.


Thanks for the alert. Avast was doing fine until now. Although we have been making incremental updates to the code, nothing significant has changed, and nothing is new at the download website either.

I have the same problem, can’t download the setup file. Have reported it to Avast Threat Labs and will forward reply when I receive it. FYI the file can be downloaded without triggering Avast using a download utility e.g. https://www.freedownloadmanager.org/

Just had reply from Avast Threat Labs, they have fixed the false positive that prevented the installer file InstallQSPICE.exe from being downloaded from the link https://getqspice.com/InstallQSPICE.exe. Anyone affected should update their installed Avast/AVG software to the latest version and restart Windows. I have done this and verified that the false URL Blacklist no longer occurs. FYI feedback from Avast follows:

Thank you for reporting this false positive.

We have now cleared its reputation in our database based on the findings and removed the detection. This change may take up to 24 hours to take full effect. Please accept our apology for the inconvenience caused.

If the detection persists after 24 hours, update the virus database in Avast anti-virus.

That is fantastic. Thank you very much! I have been impressed with Avast’s responsiveness and whitelisting tools. Of course it’d be better if we didn’t get the false positive in the first place, but this is the second-best option.


I’m an Avast Business reseller, which gives me direct access to their Threat Labs, so if you have any similar problems that I can help with please let me know.

That is very helpful. Thank you!
