Photoshop issues... Need assistance.?

Didn't even know Win7 could run on only a gig of mem.... but I have a suspicion that it's the pirated software you downloaded in an attempt to get Photoshop for free. Why? There is no such thing as Adobe Portable. It's what hackers try to use to entice gullible users to download their software which they can make money from (per download/visit), and/or to put viruses in your computer.
