When people buy a new computer, it is usually loaded with free trial software, making it sound like it is really valuable and essential for your computer use. At first it seems okay and the programs are usually pretty good, but then the trial runs out and they start to bug you.
You see pop-ups asking you to buy their software every time you turn on your computer. So our advice is to not allow trial software on your computer in the first place. It is nothing but crap and a sneaky way to sell you software.
Avoid Potentially Unwanted Programs
The first point is that the majority of these PUPs are installed by you. Inadvertently, yes, but that's little consolation after the fact. Piggybacking these unwanted programs with genuine software has become pretty much standard practice so the first step in avoiding them is to proceed on the assumption that
everything you are about to install comes bundled with something.
The second step is to be vigilant during the installation process and not just click through without checking every single screen.
There are some instances where unscrupulous developers surreptitiously bundle toolbars and other crap without providing any indication or options to decline, making these PUPs nearly impossible to avoid, but, they are generally the exception rather than the rule.
The vast majority of developers will provide the end user with the necessary options to avoid any bundled extras, although, in many cases, they will still do their very best to obscure them. Some of these PUPs can hook deep into the system and be a real pain to get rid of completely, so avoidance is the much preferred option.
✔ First Rule: when installing software NEVER accept the default "Express' or 'Standard" installation setting, even when it is labeled "Recommended".
If this setting is available then it will generally be accompanied by a "Custom" or "Advanced" installation option as well, this is the one you need to enable.
Using the Express/Standard installation option will skip the screens offering decline options and just go ahead and install everything, including any bundled PUPs.
Enabling the Custom/Advanced installation option will, in the vast majority of cases, ensure that you get to pick and choose exactly what is installed and what isn't.
What you'll need to do in these instances is enable the Custom installation option and you'll then be able to deselect any additional programs you do not want.
Here is another example where the opposite applies; rather than simply deselecting the unwanted program's installation option, the user has to tell the installer they do not want it:
