BackTrack running on a windows machine with antivirus

[Sark89]

Hi all,
Just sort of out curiosity, I run backtrack on my mac which has no virus protection on it etc etc. I was wondering if I was to install backtrack 5 r3 as a virtual machine on a windows 7 based laptop, will the laptops anti-virus software interfere with backtrack and pen testing? i.e. when running scans such as nmap will the computers anti-virus prevent the nmap scan from getting a three way handshake? Please guys don't give me grief for asking a some what nooby question, like I say, I use a mac and never used bt on a windows machine so in affect, its kind of new to me.
Thanks in advance!

The best advice would be to test it out and see

I dont think it should effect nmap scans for example. It would usually only flag malware files. Like metasploit payloads (unless your smart enough to get around the av detection ) And as sickness said it wont hurt just running the scan and seeeing if it works or not. whats the worst that can happen a little window pops up saying there a potential threat you close it and then you have an answer to your question
