I've been with Apple for many years and love their OSX and the Mac Mini, but increasingly it's been harder to deal with the overpriced and limited selection of hardware options...not to mention the sheer size of downloads vs Windows versions (I had dial-up...still do right now, but this will change soon.) The newest Mini version was the last straw what with Thunderbolt, no 3.0USB ports, and no internal disc drive option.
Anyway, I just purchased a Windows 7 Home Premium HP computer (Blu-Ray!) and am....lost. Haven't had a Windows save at work where I only am allowed on prescribed pages....have just the bare bones memory of things like defrag *shudders* and so forth, so I really consider myself to be a newbie all over again. Already dismayed I can't play some of my programs I transferred via an external drive such as flv...thought this would come with Flash installed....
Okay, meat and bones:
I'm scared to death of Bad Ware and bugs. Had ClamXAV on my Mac, but that was just a precaution. Now I want some serious protection not only via outside software, but through tweaking what Windows 7 provides in-box.
Also want some good software for playing music, movie files.
Some facts:
I do some online shopping for things I can't get via brick&mortar, but have yet to venture into banking and taxes. Suspect will be forced to do the latter soon....my state is a tad insane.
I don't do photography. Don't even own a camera and haven't snapped a picture in 15 years. At most would like to do some cropping of pictures found online. (See my user name.)
Love old movies; despite a lack of love towards 99% of what Hollywood and TV offerings, so might/maybe go into Netflix? one day. Never purchased from iTunes....is Windows music site better? Mostly download the odd fan film on YouTube.
Can't figure out how to transfer my iCal entries to Windows. Can't find a Windows equivalent on the box.
Don't do games. Last game I played was Riven (yes, the original one, which I loved, but which gave my old Windows fits. In fact, I recall most games my sibling had gave his computer fits. Will likely end erasing all the junk offerings they loaded on save for Solitaire when I'm bored waiting for something huge to load.)
Been using Firefox and Thunderbird for Macs, but have downloaded the .exe file for IE9. Is it better/safer than FF? Mail?
Oh, and though very paranoid about security, I'm also paranoid about venturing more than one short line into...changing internal software code. Turns my hair white. I'd show you a pic to prove it, but don't own a web cam or that aforementioned camera.
Thanks for any suggestions offered based on the above!

Pretty sure I'll be running to the Problems forums soon enough in a full panic later, but for now...hopeful of new purchase and format.
*deep breath*

Oh, and how do you get rid of unwanted 'free installed' advertising sofware already loaded on courtesy of some idjiot? Don't want all of those game or even know what Blio? Tangent? What is this stuff? are. Don't want what I can't decipher.
