Avast Antivirus Web Shield chokes on:

http://mirror.catn.com/pub/kde/stable/4 ... n.tar.bz2|>aspell-x86-mingw4-0.60.6.3-bin.tar|>bin\prezip-bin.exe

which it blocks as allegedly the High Severity Threat:Win32-Malware-gen

I'm fairly sure this is an Avast false positive, but would someone like to investigate and either remove the malware or poke Avast, as appropriate?

In the meantime, any advice to complete my installation?

Thanks!

I am not sure of the correct procedures for reporting false positives to antivirus vendors, but someone on that list will likely know the appropriate method.
