Yep, its some kind of virus and I cant get rid of it :(
now Im scanning my computer with ad-aware 2008 (updated of course) and I hope to see some dead viruses, but please, tell me what you know about this stuff :( Im a n000000000b

Use Kaspersky instead.

alright, after this scan I will scan that with kaspersky

after reading a few arctiles I deleted winupdate.exe and I also scanned my computer with "SpeedUpMyPc 200"

SpeedUpMyPc doesn't sound like a good program. Although I haven't used it, so I don't know. Kaspersky is one of the best antivirus programs out there, but I think Avira is the best free antivirus. Although you can use a registryhack to use Kaspersky for free.

Try AVG.

Start->All Programs->Start Up

Delete Calculator.

You seem to be using every single program that is advertised on the internet.

You know.
Those, that allow Trojans to get in?

Get Spybot and NOD32

Type msconfig in run.

In the startup tab, uncheck calc. Hope that'll help. :)
