Hi, I've installed a virtual Lion machine using Parallels 7 on Macbook Pro 13" 2010 using latest build of Lion. I will be installing and testing some software from third parties and want to ensure my machine is not compromised by keylogging or other malicious software. I already checked the "Isolate Mac from Virtual Machine" on Parallels after taking a snapshot of the original Lion install. Is there anyway malicious software migrate to Lion on my laptop or other computers on my wireless router. I don't have a network drive. I am using a wireless linksys router in a Mac and PC household. Will reinstalling the virtual Lion install from the first snapshot also kill any instance of a virus? Thanks. I used Windows for 20 years and was always very careful about getting any viruses.
