Hi Luke,

I have Kaspersky free installed on my computer and all of a sudden today, after years of having and using your software, Kaspersky deleted multiple version of this application because it thinks is infected with VHO:Trojan.Win32.Convagent.gen. I tried to download it again from your site and it doesn't let me.
Do you know what can cause this? Something in the SW behavior that looks like a trojan, or Kaspersky went crazy? Real trojan?

Thanks,
Miti

Now it won't even allow me to download anything from your site. It says:
"Visiting a dangerous website has been prevented"

What is going on? Has Kaspersky gone nuts? Can other people check with different antivirus SW?

I had the same problem with Windows Defender a few years ago. I reported the problem to them and they published a revised virus scan file to correct the problem.

Here is a link to report to Kaspersky:

I tested my program files on my work computer. It's running Microsoft Defender for Endpoint. This is the enterprise version of the microsoft security software. No virus was found in the files. Definitely a false positive.

I have users of my HP 3478A multimeter control software that are getting checksum errors when trying to read the calibration data. This is happening with newer AR488 firmware versions. Older firmware works fine.



My program works with AR488 0.49.14 but fails with AR488 0.51.18.

If you have checksum fails you should check your firmware version. You may need to downgrade until I find the cause of this problem.

Your software made my day! I bought a 3478A a few weeks ago and was becoming anxious that the battery would run out as it was older than I thought when I bought it. The battery is impressively still at 3.5V even though its date coded 11/87. So I was happy when I received the PCBs for AR488 today from JLCPCB, I got the 24pin connectors from Digikey earlier this week.

As you note above, I had to install AR488 0.49.14 firmware from the archived ZIP file in the github repository to make it work. I checked the AR488 issue tracker https://github.com/Twilight-Logic/AR488/issues?q=is%3Aopen+is%3Aissue and there's apparantly nothing reported there about the problem. We should. Is there a way to dump the communication between your software and the AR488 for debugging?

The automatic GPIB address search and edit calibration data dialogue are very nice features of your software!

I've observed a bug that sometimes it display Ohms instead of DCV. Clicking the function radio button corrects the display, so it's just a minor source of confusion. See screenshot.

Thanks a lot for your work  :-+
