'emulation or virtualization' related question

hello folks

there is a software (TeleCharts) that i need to download for work but there is a slight problem. the software doesn't have a mac version. it's only made for windows based computers.

after doing some googling, i found out that i can only run the software by using emulation or virtualization on my mac.

would doing this make my mac run slower or make it prone to viruses? because basically i'll be running a windows based program on my mac...

i would appreciate any comments.
