Puzzled & alarmed: new msg at boot-up, and lost Restore PT

[mmmhhhm]

Hello Hello

I'm running Win 7 Home Premium on a Gateway with plenty RAM and hard drive.
About three weeks ago, a new message appeared at boot-up. In a congratulatory tone, it told me I had a successful interactive log on.
Where? With whom? Why?


My system also says there is no Restore Point, and I've never done a back-up.
Rather puzzling, as previous experiences over the prior 3+ years would seem to contradict this.

I have a little home LAN (two desktops, two laptops, Cisco Lynksys E2500, my desktop = straight piped into the router, cable modem), use Avast and several anti-spywares, don't broadcast the SSID, and love the DNT (Don't Track Me)

So...what is up with this? Did Microsoft pull yet more crap as a result of 'patches'? Or is someone ON my computer remotely? (I am the ONLY person physically who ever uses it) Would appreciate some insight(s) into this.

Thanx and a hat tip from MHD

What is it that prompted you to ask now about a 3 week ago event?

I've never seen a Win update that did away with restore points.

Have you scanned your systems with Windows not running?
You might try one of the LiveCD style scanners
Boot from a CD or USB drive and run a scan without having Windows running.

An example would be Bitdefender Rescue CD

It might be a good idea not to remove or quarantine anything is you suspect that might keep your system from booting (unless you're ready to make repairs on the spot).
