The new app is only downloaded once, if it is not already on your system.

However, if McAfee keeps quarantining the app, boinc will think the file needs downloading again because McAfee has moved it.

To get around it, I suggest setting "no new tasks" for CPDN. Suspend any current 8.29 wah, check McAfee quarantine and restore the wah_8.29_windows_intelx86.exe file if it's been quarantined. Then resume the tasks. Check McAfee doesn't quarantine the exe again, it shouldn't do, this is how I worked around the problem when I was developing the new app.

To get around it, I suggest setting "no new tasks" for CPDN.

Done.

Suspend any current 8.29 wah,

There were none. (Two 8.24 are there with time on them. One running, one waiting to run)

check McAfee quarantine and restore the wah_8.29_windows_intelx86.exe file if it's been quarantined.

It is there; nothing in quarantine. I probably restored it last night, time stamp is 23:56 yesterday.

Then resume the tasks.

Done.

Check McAfee doesn't quarantine the exe again, it shouldn't do, this is how I worked around the problem when I was developing the new app.

It has not quarantined it yet. We will see next time I get an 8.29 task.

Failed anyway. File is quarantined.

Try again, set no new tasks etc. Every time it's quarantined, a new task will trigger a new download.
It's a timing issue I think.

Download a new task, then suspend either the task or all computation before it gets a chance to run. Look to see if the .exe was quarantined immediately on download. If so, restore it and use whatever tools the AV program provides to say "I trust this file".

If it wasn't flagged immediately on download, look to see if the AV provides an option to scan a single file on request (most do). Scan it, and respond to any warnings/options it generates. Again, the idea it to get to the point where you can say "I trust this file".

Only then allow the task to start running.

One was downloaded but not started, so I suspended it. It was not yet quarantined.
There is a way to tell it not to scan a file, but I do not think it works. I can go through the motions, but it never acknowledges that it has done it.

I could scan the single file, and it quarantined it right away.
There is one file in the list of quarntied files-- this one. It says

Item: wah2--8.29-windows-intelx8
Threat:RealProtect-L S6e9fdca5e68a
Dated: 15/02/2024 12:56 PM
C:\ProgramData\BOINC\projects\climateprediction.net/
RealProtect-L S6e9fdca5e68a

I have a choice of Restore or Delete. No option to say I trust that file.,
If I select Restore, I can then go to where it allow me to say to not scan it, but it has no way to display a list of non-scanned files. Furthermore after I tell McAfee to not scan the file, it pretends, but does not do it; i,e,, if I scan it again, it quarantines it again.

Only then allow the task to start running.

I did not do this yet.

---

With my McAfee, once I've restored the file, it does not quarantine it again. I think that's how you tell McAfee the file is trusted. That was all I had to do.

However, if the file is replaced again, even if it's exactly the same file, McAfee will quarantine it again. So the key is not have a task start unless the exe is restored.

With my McAfee, once I've restored the file, it does not quarantine it again. I think that's how you tell McAfee the file is trusted. That was all I had to do.

OK: I told McAfee to restore the file from the quarantine. I checked and it is there where it should be, right after the 8.24 one.
I then told Boinc-client to resume the process (it had never started so it is now in ready-to-start state).

However, if the file is replaced again, even if it's exactly the same file, McAfee will quarantine it again. So the key is not have a task start unless the exe is restored.

I have two 8.24 tasks running and one waiting to run. The 8.29 one is now waiting to start. app-config allows four climateprediction.net processes to run at a time, but my machine is busy with other Boinc tasks, so it can be a while.
Boinc is allowed only 7 of my 8 cores. This is a machine that has little to do other than Boinc-client although I will be running TaxAct soon.

Ok, hopefully that'll fix it. Otherwise I'm not sure what else to do.

Ok. I've been away but will be home tonight. I will try on my McAfee windows pc and let you know.

13 successful tasks from 1006 so far. I see the only two hard fails so far from 1007 look like all six task failures are variations on the exe file not being present.

I have 11 batch 1006 tasks in progress, and 2 batch 1007. The leader has reached 76%, and tail-end Charlie is approaching 28%. None has shown any sign of distress so far, and I have no stuck uploads. Fingers crossed that continues.

Failed again same way.

Hi Jean-David, I've got this working with McAfee. For reference I have: McAfee LiveSafe 1.14.212.

Starting from scratch, that is, no wah-ri 8.29 tasks and no wah 8.29 executables in the ...../boinc/projects/climateprediction.net folder.

Set 'Allow new tasks' for climateprediction.net in boincmgr.
Starts download for a new wah-ri 8.29 task. 'Suspend' the climateprediction.net project in boincmgr -- this will allow the download to complete but not start.

Open McAfee and from Home page go to 'My Protection => Real-time scanning' in the left hand bar. Make sure 'Real time scanning' is ON. It's not possible to exclude files without it on.

At the bottom of the real-time scanning window, click on 'Add file'. Navigate to the ../boinc/projects/climateprediction.net folder, select 'wah2_8.29_windows_intelx86.exe' and add it. It should then appear in the list of 'Excluded files'. If it doesn't, do it again (for some odd reason, I find I sometimes have to do this twice). Then in boincmgr, Resume the climateprediction.net project and the task should then run fine.

If boinc has already downloaded the exe file, you might find it under 'My Protection => Quarantined Files'. In which case, select it, click 'Restore'. Then as above, go to 'Real-time scanning' and 'Add' the file to the excluded list.

If the boinc data directory is hidden from you to get to the exe in File explorer, turn on 'View - Show - Hidden folders'.

Hope that gets things going for you.

p.s. we are looking into why this is tripping a few AV systems. I can assure you there are no viruses on my development PC.

Hi Jean-David, I've got this working with McAfee. For reference I have: McAfee LiveSafe 1.14.212.

I have what they call McAfee Advantage Individual
Version 1.14.212
Build 1.1.2569.0
So it is probably like yours.

Starting from scratch, that is, no wah-ri 8.29 tasks and no wah 8.29 executables in the ...../boinc/projects/climateprediction.net folder.

Right now, my Windows 10 machine has No New Tasks set for climateprediction.
There are also some other files in that directory with 8.29 in their names. .zip files. there was the 8.29 ,exe file, so I deleted it. There are no files in quarantine.
There are four 8.24 tasks running.

I do not recall that they are called wah-ri. IIRC, they are called wah2_8.29_windows_intel86.....

Set 'Allow new tasks' for climateprediction.net in boincmgr.
Starts download for a new wah-ri 8.29 task. 'Suspend' the climateprediction.net project in boincmgr -- this will allow the download to complete but not start.

I hesitate do do this now because if I allow new CPDN tasks, I may have to wait a week or so until at least one of those 8.24 tasks finishes. Maybe if I suspend one?

Open McAfee and from Home page go to 'My Protection => Real-time scanning' in the left hand bar. Make sure 'Real time scanning' is ON. It's not possible to exclude files without it on.

It is ON,

At the bottom of the real-time scanning window, click on 'Add file'. Navigate to the ../boinc/projects/climateprediction.net folder, select 'wah2_8.29_windows_intelx86.exe' and add it. It should then appear in the list of 'Excluded files'.

I have never been able to find a list of Excluded files. Where is it?

When I click Add file, a pop-up menu of files in the right directory appears. If I click on the file to be excluded, nothing happens. I can select either open or cancel. If I try open, it does not really respond. And I do not really want to open it anyway. There feels to be something wrong there.

If it doesn't, do it again (for some odd reason, I find I sometimes have to do this twice). Then in boincmgr, Resume the climateprediction.net project and the task should then run fine.

If boinc has already downloaded the exe file, you might find it under 'My Protection => Quarantined Files'. In which case, select it, click 'Restore'. Then as above, go to 'Real-time scanning' and 'Add' the file to the excluded list.

If the boinc data directory is hidden from you to get to the exe in File explorer, turn on 'View - Show - Hidden folders'.

Not a problem.

Hope that gets things going for you.?

I have never been able to find a list of Excluded files. Where is it?

On my version of McAfee, the list of 'Excluded Files' is on the same settings page as 'Real time scanning'. The file list appears above the 'Add file' button. You probably can't see it because there's none added?

When I click Add file, a pop-up menu of files in the right directory appears. If I click on the file to be excluded, nothing happens. I can select either open or cancel. If I try open, it does not really respond. And I do not really want to open it anyway. There feels to be something wrong there.

Yes, as I said in my earlier message. For some reason I sometimes have to try 'Add File' twice on the same file before it appears on the page. Probably a bug or McAfee being slow. Try it again, it does work.

I had a response from McAfee and they have accepted the binary file wah2_8.29_windows_intelx86.exe for whitelisting as a false positive. Hopefully this will soon propagate down to users and stop being a problem.

That is probably the case.

Should I put the old 'wah2_8.29_windows_intelx86.exe' file back and try again? I am keeping it in the trash bin.

Sure. Now McAfee have emailed to confirm it's a false positive it's a safe thing to do.

I just updated my McAfee stuff but all seems to be the same. E.g., Version 1.14.212, etc.
