Pros: This does in fact work on xp, because I installed it to my dads computer and it worked fine, he upgraded finally to windows 7 and it installed perfectly fine. Works great, catches everything.

Cons: A little slow at updating.

Overall Review: I've used almost every internet security package out there, including the free ones. Kaspersky is by far the best of all of them.

Pros: Great for music, great for movies. I owned the HD 555 headphones before these, they don't ever compare. When the volume is louder, the 555's hissed and popped, not so with these. Watch Transformers 2 at the beginning when the Fallen slams his foot on the ground with any other headphones, you'll know what I'm talking about. I can hear things on movies and music I didn't know was there before. Also, these are very well made, nice box, heavy duty cord and the phones are really light.

Cons: Price, but you get what you pay for. Headphones are a little tight, but hopefully they'll loosen over time.

Overall Review: These brought together my home theatre. LG 42" 120hz lcd tv, Sony 7.1 receiver, PS3 slim 250gb, Sennheiser HD 650, Logitech Harmony One remote, Monster HTS 1000 MK III surge protector, Monster Cable HD 2000 hdmi cables
