The BS Test will only change clock time for a matter of a few seconds. There is no need to manually change the clock back.

Yes when the clock changes back it does cause issues with some security software, but that's a small price to pay for those who wish to continue using BS. If possible make BS an exception on all security software.
The cache zipped file 'I' supplied, I think was zipped with either the freeware TUGZip or mac osx's zip compressor which should be cross-platform compatible. TUGZip does the same thing as WinRAR & more, but is free. Zip is a more common format than rar, as not everyone has a utility to open rar files. This cache is simply an alternative to the one offered by AW & was offered to help the users in this & another couple of posts since that cache did not appear to work for them, but this one did. File appears to be Zip v.2.0. WinRar, Tugzip & another two extractors I used had no problems with opening that zip file.

More information about those who are attacking the Gnutella network? erm .. there's even a special section on this forum which discusses a part of this & links to other posts discussing about this. Not to mention the thread in question repeated in almost every section of the forums. Did you try the forum search function?
A link toward the topic of spam Virus thread: Typical virus spam file sizes - Make a note of them (click on blue link to see). Although this article was written as advice in techniques for LimeWire users, it also applies to all other gnutella clients: How to find music

BTW the same company (MusicLab LLC) that took over Bearshare also 'hijacked' ShareAza, took over their site & their forums. Now the original ShareAza devs have been forced to move to Sourceforge (just weeks ago), which is a site for open source dev projects. Any version of Shareaza above 3 is a fake & is basically identical to iMesh & bearflix. There is a link between MusicLab & the RIAA.
