Hi we often encounter a lot of good stuff on the internet some are free, others are trial and some paid ones online.
The internet is big. As of now you may have stumbled upon a what we called Pirated Software. There are many out there specially the famous ones.
What is Pirated software?
We will define it as Illegal/Unauthorized use, modification and/or distribution of software...
Well you might be thinking that its cool to obtain copies of this stuff or have in your mind that who cares i can save money doing it.
Think again. Pirated software or Illegal versions of it are mostly (if not) all packed with Viruses, Trojan Horses, Bots, Ransomware and other malicious software that may have been intentionally coded by the cracker (aka. hacker). Do you really think they will freely distribute cracked software out of charity?
Have you ever encountered that websites deny you access to their site ( your computer/network maybe sending automated queries...) or your computer is suddenly acting strange or maybe your antivirus have gone haywire. Most likely you've have installed yourself a Malicious Software.
An Antivirus solution is a line of defense not a fool proof solution. If you are familiar with City of Troy in Greek mythology the very same concept what a Trojan horse in our computer does. Most common trojan horses will get detected by you favorite antivirus solution but the newer ones and the more shady ones will bypass it very easily and without anyone knowing until it does it damage. The effect may not be immediate but its there.
Besides that most well developed application software are the paid ones simply because the developers are able to fund their project with better equipment and if necessary come up with a good team to help him/her in development. They have put their time effort and dedication to come-up with something good. Software development may long hours and take years to perfect.
Conclusion:
The use of Pirated Software is illegal it also puts your computer and your files at risk in worst case it could Compromise you privacy.
You should always use legitimate software from legitimate source not only that its safer you'll get most updates free. You're also entitled for support.
