any way i recommend u to use avira or avast antivirus, zone alarm firewall , malwarebytes anti malware and super anti spyware which are all the best to my view...
too many applications, calm down with multiple software apps that do the same thing.
one good internet security suite should have all the tools that you need.
and I hate having security software from multiple manufacturers, cause conflicts..
just because you can download a lot of software and even hack them open,
you don't always need too.
