Windows 7 services problem

[Pjieter]

I'm running a Dell XPS 15, OS: Windows 7 Ultimate x64
Today I tried installing Linux Mint next to Windows 7, thought I might like it.
When I booted from the live cd, and tested Mint for a while, I noticed that I couldn't connect to my wireless network. I wasn't able to enable my wireless network adapter.
Because I didn't like that, I rebooted my PC in Windows again, and decided to leave Linux for what it is.
But the problem is that in my Windows 7 machine, I also can't make internet connection, my wireless adapter seems to be disabled or something.
Also, my antivirus-programs (Microsoft Security essentials & Avast) are stopped, and I can't put them back on (time-out error with Security Essentials).

If any of you guys could help me out, would be great. If not, I guess I'd have to go for a format c: :s
I think it has something to do with 'services' that can't be enabled, but actually I don't have any idea on how to fix this.

Thanks in advance! :)

there should be a button or key to turn the wireless on and off ,i assume you tried that ,also did you try or can you connect wired to the router/modem .
a lot of what you say excepts live Linux points to a Trojan or virus if you cant get on line with the laptop i suggest downloading something like Superantivirus or malwarebytes on a working computer and transferring to the laptop and installing and scanning with it .
