I recently experienced a problem with WyUpdate, where it detected and deleted files due to a virus alert during an update. I would like to understand the reason for this and explore any possible solutions. Can you please provide more details on the deletion and potential file recovery options?what is the reson for the virus
wyUpdate doesn't respond to anti-virus programs. It doesn't do any work on their behalf. If your files are being deleted it's due to the anti-virus program itself.
Also, don't use any third part anti-virus. Use the built-in Windows Defender.
And code-sign all your executable and dll files.
