Both? All of these have potential to interfere in unusual ways with unsigned open-source software (which many virus scanners attack as "evil"). Having multiple virus scanners installed is highly discouraged as they are likely to interfere even with each other.

For virus scanners, most allow you to configure exceptions. For example, please create an exception for the SageMath installation directory, as well as any LaTeX distributions you have installed. > My warning is not potentially wrong: a user under windows8 with Mcaffee is >> not able to use sagemath9, no patch known to date, it is a fact that it is >> better to know to not lose his time >> > Maybe, but no one has confirmed yet what the actual problem is, so it's not helpful to make broad pronouncements that may not apply to most users. I've seen at most 2 other reports of this issue so it clearly isn't just you, but please let the software developers make pronouncements like this if/when we have full information. > it is a wonder in itself that 8.9 worked with Mcaffee installed and > running. > It's not always a problem. I haven't seen too many problems with McAffee interfering with Cygwin programs. Avast is much worse. But I haven't done a comprehensive review of how different virus scanners affect Sage/Cygwin. Perhaps I should install them one by one in a VM and see but it's time I don't have. I would like to have comprehensive instructions for how to add path exceptions for different virus scanners. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
