I have NIS 2011 on 3 PC's each running a different OS (Win7, XP, Vista). I transported about 3Gb of files from work to home on a DVD and was very disappointed in how long it took to simply transfer the files from the DVD to my C drive. I wondered if maybe NIS was having to individually scan each file? It took nearly AN HOUR to just download the files. This is a NEW laptop, has had NIS installed from the beginning and my work PC is absolutely virus free. Is there something I can temporarily adjust to speed up the download? I know 3.5Gb is a lot of data, but AN HOUR! Laptop is a HP G72-261US with 4Gb RAM, 1.86GHz, 5400RPM 320Gb hard drive
