Great, I've installed both now and everything is working perfectly. thanks !

Thanks for your answers. I purchased Bitdefender Internet Security 2012 and MalwareBytes. First I installed MalwareBytes because my Kaspersky license expired 3 days ago and I got infected with a virus called isecurity.exe and after searching a little bit in the internet I found a thread here in MalwareBytes regarding that issue so I thought this software already had this malware/virus in its database. After running a scan with MalwareBytes I tried installing my Bitdefender Internet Security 2012, this is the message I got: My computer OS: Windows 7 Home Premium (64 Bit) Would it make any difference if I uninstall MalwareBytes, then install Bitdefender first and after having it installed trying to install MalwareBytes again?

Hello, I bought MalwareBytes yesterday along with BitDefender anti-virus and I couldn't install bitdefender having MalwareBytes in my computer already. My question is: do I need to get an anti-virus or by just having MalwareBytes installing I will be protected ? Thank you.
