Since installing Bit Defender Total Security 2012 Ive been experiencing slow shutdowns in Win 7 x64. I dont know anything about windows processes. Which processes are used to shutdown Windows? Are any of them likely to be interpreted as a threat by Bit Defender? Is there anything I should whitelist? or any other explanation for the slow shutdown? Ive done full system scans with a couple of different AV and anti malware programs and theyve all been clean.
