I found some very interesting info on How-To Geek:
Here’s What Happens When You Install the Top 10 Download.com Apps
"We installed the top 10 apps from Download.com, and you’ll never believe what happened !
Well… I guess maybe you might have a good guess.
Awful things are what happens.
Join us for the fun !
We’ve been railing against freeware download recommendations for years,
and recently we taught you how to test any software safely using a virtual machine.
So we thought, why not have some fun and see what really happens if you download software like a regular clueless user might ?
For the purpose of this experiment, we’re going to just click through all regular installation screens with the default options using a fresh virtual machine.
And we’re going to install ten applications from the most popular downloads list.
And we’re going to assume the persona of a regular non-geek user.
Why would we choose Download.com ?
Because their policies page states clearly that they do not allow malicious software on the site,
and further that they do NOT accept any software that contains the following:
Software that installs viruses, Trojan horses, malicious adware, spyware, or other malicious software at any point during or after installation.I mean, with all those protections in place from the trusty people over there at CNET, why would anybody worry ?
Software that installs without notice and without the user’s consent.
Software that includes or uses surreptitious data collection.
Software that diverts or modifies end users’ default browsers, search-engine home pages, providers, security, or privacy-protection settings without the users’ permission.
Software that installs in a concealed manner or denies users an opportunity to read the license agreement and/or to knowingly consent to the installation.
Software that induces installation by making false or misleading claims about the software or the software publisher.
I mean, CNET News is a trusted source, right ?
Full story: Here?s What Happens When You Install the Top 10 Download.com Apps
It´s wellknown that CNET´s download.com gives you a lot of "extras" when you download from them...
And nowadays you can not even trust SourceForge....
This is the reason for my recommendation to always download directly from the creator of the software,
or from a webbsite they direct you to.
But that doesn´t mean that you are always safe...
Calendar Of Updates has been monitoring this problem for years,
they have a list of software that gives you toolbars, cleaners, optimizers and other crap when you install them.
It´s called Installers Hall of Shame
If you should install some software and notice it installs (or try to install) "crapware", then get a (FREE) membership over at Calendar Of Updates and report it so it can be added to the list.
Also remember that many legitimate software want to install "automatic update-programs" that are not dangerous but will run in the background, take system resources and slow down your computer.
So be careful about what you install !
