You gotta see this W7 Behavior, weird

ok so I downloaded the 64bit version of the RC and installed right away on the test machine, then after setup was complete I changed the desktop to my favorite image (a bullfighter).

Next I downloaded AVG (latest) from download.com, funny thing is that after it was downloaded (when I went to double-click to open), it didnt have an extension, the mouseover gave me a 7zip file, but it didnt have a 7z extension, and when I doubleclicked it asked for what program to open with, huh?

so I tried to change the extension to a zip, duh wrong, then after applying, changed it to .exe, which then gave it a .exe.zip, not good, so I went to change thru properties and removed the zip, and added exe with IE8 as the program to open with, I didnt do it, I tried to give it a different "other" (none) program but it gave it IE8.

So then I went to file and double-clicked to open, and W7 went berzerk, trying to open, then closing IE8 windows so fast you gotta see the video I took.

Here's the link:

What finally stopped this was to revert to old name, zip.

wierd

usually you get an exe with the avg free download, so maybe you got some strange downloadlink?
and why would you open an exe with IE, IE can barely open webpages ...
