Hi Jos,
I agree with Tracy about Comodo firewall. I'm using it for a few years w/o any problems. Their AV is another story. It's not any good. It was mistake that they release it.

I have now uninstalled Comodo and gone back to ESET and the problem has disappeared.

Even when I told Comodo to ignore the drive where the project was being compiled it still had the problem. Only uninstalling Comodo resolved the issue.
