Something Weird Happened to my PC

[Tpex]

Switch on my PC one night and it said it had a new network (different name from the old one) ESET's firewall acted like it has just been installed, asking me the permissions for everything, and the Last.fm scrobbler won't connect to iTunes, oh and my Object Dock lost all its settings, can't figure out what the hell changed and therefor how to fix it.
Any ideas?

OS: Win7 Ultimate
Latest ESET, and no changes where made to the network recently

Oh I forgot to add, my ADSL connection doesn't auto dial anymore (PPPOE) it doesn't even ask to connect

Windows update perhaps, tried system restore?

Windows update perhaps, tried system restore?

Updates are set to manual, now it gets weirder! system restore is set to off (never disabled it)
So I try an enable them and it says:

Could not apply the settings for the following reason:
The Filename, directory name or volume lable syntax is incorrect. (0x8007007B)

Then

There was an unexpected error in the property page:
The Filename, directory name or volume lable syntax is incorrect. (0x8007007B)
Please close the property page and try again.

Then it seem system restor is enabled, but there are no past restor points

have you run a virus scan?

sounds similar to when my pc got knocked bad, same error on system restore.

Click Start, type SystemPropertiesProtection.exe. The System Restore Properties window will open.

You may see two C: drives in the listing with the same Volume label (see figure below). Deselect the checkbox for the duplicate volume, and enable the checkbox for the correct drive (the one with Windows logo).

Just experienced something similar. All my shortcuts got wiped from start menu, firefox lost its settings, bookmarks. Luckily i keep firefox backups. System restore fixed my icons. Installed the windows update which contains the september malware removal tool today - wonder if that broke everything?
