Hey guys,
can u help me please with this problem, everytime I start my pc this error occurs:
module 4271830.dll can not be found. by clicking OK it disappears. I think it begon after the last windows update. I couldn't find any solution in Microsoft.

Hi townman, welcome to the CPHF.

Google doesn't know what it is either.
Might be an idea to follow the Prework link in my signiture and post the resulting logs.

thnx GaRHaR,
I followed your advice and came to the step where i shoud run an AVG scan, but i have latest version of Norton int. sec., should i use AVG anyway?

Yes please

AVG spits out a log file for our security team to have a look at
This AVG program is an anti-spyware version of AVG also...it scans for different things than Norton.
