r, I thank you for your kind answer.
Unfortunately, you have not read, with enough attention, my post.
I have NOT tweaked Opera. Only Firefox; only Firefox 3.
X, to be more precise. Firefox 1.X and 2.X are
working fine, "out-of-the-box". They do not create this kind of problem.
IE 6, 7, or 8 does not
need to be "tweaked" in what concerns the "file attachment policy".
Opera 9 or 10 does not
need to be tweaked.
Safari 4.0.X does not
require any tweaking, either. (I just have tested it!)
K-Meleon, QtWeb, SeaMonkey, Luna and ALL the other available browsers, for Windows, based on Gecko,
Trident, and WebKit engines, are working fine. They are ALL conforming themselves to Windows security
policies. They do not have to be "tweaked", in order to download "unmarked" files.The only really "indisciplined" browser out here is... Iron
. And I underline: only
Regarding my anti-virus program, well, I have to disappoint you. I am not using ANY kind of AV protection!
I use Opera 10 (+ Sandboxie - if I navigate on unknown websites). If I want more protection, I activate the very
useful application called AVG LinkScanner - wich is far superior to WOT, or McAfee SiteAdvisor, for example.
(more info about LinkScanner, here: http://linkscanner.avg.com/
From all the browsers I know, Opera has the best "Security Record" - at least, according to Secunia. By the way:
if you have time, please read this article: "Security competition reveals new browser flaws". Here's the URL:http://www.windowssecrets.com/2010/04/0 ... wser-flaws
According to its author, "For the second year in a row, Google's Chrome was the only browser not hacked — not
because it was unbreakable, but because the other browsers were easier targets. Compared to IE, Firefox, and
Safari, Chrome is a new browser
." (Opera was deliberately excluded, for the second time, from the hackers'
contest. Guess why...)
More of that: after the working day has finished, I restore my PC to the state it was right after the "clean"
installation of Windows XP.
Similar to the procedure from any Internet Cafe...
Before doing this, I save all my downloaded files on a CD-RW disk - if, of course, I download any file.
For "office-like" activity + CAD + photo editing + etc., I use a second PC - which I never
connect to Internet.
(Note: the CR-RW solution is better than the USB stick/HD solution, from the Security point of view. Even if it is
a little more uncomfortable.)
I am sorry: you have lost your bet...
My problem - which, I repeat, is affecting many others - has to do with the Operating System (Windows XP SP2).
And not with the Antivirus.-
