Well, this is awkward. Once my laptop has booted and before I do anything (no browser, no programs whatsoever), I check what avast is doing and see that it is checking the web. In the Statistics window, it scans and scans endless pages of pr0n pages on the internet. Occasionally a pop up window appears, saying that some process has been blocked. Always with an dmw.exe as the culrpit. This exe sits in the Lenovo-folder, i haven't found anything useful on the web for that file. then the scanning stops only to start anew half a minute later.
I did a boot-scan with avast to no avail. A malware-check too, I attach the report. Maybe someone has a clue what is going on. The avast module is in german and I have posted this in the German thread also. I hope that is okay, since there is no answer there.
Thanks.
