Hi,
These are all good points. I also had severe issues with Antivirus - it
slowed down or prevented a lot of the network access. The IT services
had to add exceptions.
But you describe that it only happens after a couple of days of usage,
which is strange.
If you find out what the issues really is, please let us know, so we can
learn.
