Greetings. Got a question here. I want to know, can I install multiple anti virus? I have ESET Smart Security for now and I want to install another anti virus without firewall. I think, I'm going to install Kaspersky. So now, can I install another one or not? If answer is no because of system resources, do not say that. I don't have any problem with that, even if my Windows gets crashs. I'm on Windows 7 64-bit, Ultimate edition. I heard if I install another one, none of them works perfectly. So now, it is true? Thanks for answering. Cheers, Shitu.
