I've had a couple of tasks errored this morning by Avast refusing to allow tcl84.dll to load: the tasks were from the long queue, running version 8.41 (cuda60). Symptom (apart from the Avast pop-ups) is "exit code -1073741790 (0xc0000022)"

The same machine ran identical tasks downloaded yesterday, so I think this was caused by a faulty antivirus update overnight. I've reported it to Avast as a false positive.

Same problem from three hours ago, have run the short runs without problem till then. Have checked the Avasti virus chest and see two elements from two failed downloads.
Does anyone know how to deactivate BOINC/GPU files or do I have to uninstall Avasti completely?

Another download seems to have failed, the problem appears to be with the td84.dll file, it keeps getting continuous retries

Can you just exclude the file from your anti-virus checking it? Most people end up excluding the whole Boinc directory as any true virus will try and infect other parts of your pc and then be caught, while false positives will be ignored.

I was also having problems with the download for the tcl84.dll which was being blocked by the Avast Web Shield. Temporarily disabling the Web Shield allowed the download to complete.

The paths C:\ProgramData\BOINC\projects\...\* and C:\ProgramData\BOINC\slots\* were already in the Avast file system exclusions. I went ahead and added C:\ProgramData\BOINC\projects\www.gpugrid.net\tcl84.dll.

We will see if that helps until Avast corrects the issue. I also reported the tcl84.dll file as a false positive. FYI, I have not noticed this problem with the McAfee VirusScan Enterprise.

Thanks for confirming. My index case machine has completed one long task, and will shortly finish a second, since I took similar action.

Please use the directions at https://www.avast.com/faq.php?article=AVKB21#idt_07 to submit the files to Avast for false positive analysis.
