I am facing some problem with the free version of the Avast. I have Windows XP professional installed on my computer and after installing that I found that the performance of the virtual machine slows down a lot. I am having the VMware Server 1. Can you tell me that what could be the problem with this? If I try by disabling the real time protection then the it is running the virtual machine without any problem but as I activate the protection then it shows me the same problem again. Please help me with this.
