Install fails with Kaspersky Internet Security 2011?
I'm having a really strange issue installing Calibre. The first time I installed, it worked fine. However, since then, every upgrade installation hangs at the checking disk space stage, and at that point KIS goes mad and drains almost all the CPU.
If I kill KIS before installing the update, all proceeds OK.
Has anyone else seen this behaviour, and even better, does anyone know how to cure it?
