Hello P3t3rb0nn, my friend,
The anti-rootkit discussion will be taken onwards, I presume. I think it will be an evolving threat in the future. I totally agree that a lot of malware, and programs with virus- or trojanlike activities are wittingly or unwittingly downloaded onto a machine. That means great pity for the uneducated. That is why we have to advice people strongly against clicking on anything they see or that which seems interesting. Idle promises are more likely than not meant to be just that. So an extra line of defense goes according to these lines, imho: be responsible on the net. Know your system in so far as necessary. So use a checksum program, check on unknown program files, keep files from hiding on your system. Use small helpful utilities like FileAlyzer, a Binairy Text Scan program, a hex viewer to look for abnormalities that else won't show. These are things you should use whenever you smell there is something fishy going on on/in your system, a xxx.dll or cpl that does not seem familiar at first hand, a file that is found in another path than normally routine, etc. etc. There will be new handy dandy tools coming up for this purpose, and screening your OS from an uncompromised OS can be helpful too.
greetings,
POLONUS
