The first thing I install after a refresh OS installation is Comodo Security Suite. I guess thats what everyone should do before visiting any sites. I usually download and keep most important installers such as Comodo, Firefox, Chrome etc, before starting the installation. That way no need to browse before installing virus guard. I guess drivers don't count here ? xD

I think rest of the stuff is just user preference rather than mandatory. Other software which I installed right after are,

01. FileZilla,Bitvise SSH Client.
02. Adobe Photoshop
03. Adobe Dreamweaver
04. VNC Player
05. qBittorrent
