Honestly, I'm quite surprised about the strong reaction. I thought it was common knowledge that this kind of software is full of bugs. During the last year, I discovered dozens of bugs in different widespread anti-virus products.

Concerning your question: In general, I consider it quite difficult (if not impossible) to give a concrete answer. The software, as it is now, is just in a horrible state. Depending on what your threat model is, how experienced you are as a user, it might very well decrease your system security.
