Slow computer, why?

Today I was asked for help to see a new computer that is slow and full of viruses. But why?

Viruses are malicious programs that enter the computer with the user's exclusive permission, that is, if you keep a computer still connected to the internet, viruses would hardly enter it, just like with servers (where there are no users operating it).

As soon as someone is using that machine, they can be much more exposed to vulnerabilities than before. This is due to the fact that there are many programs that deceive their users.

Who wants to install a virus on your computer? Surely you will say "no, never", but if it comes in the form of a "friendly little friend"?

What I mean is that if you have a computer and are looking for programs to download from download sites, the risk of acquiring viruses and other unwanted programs is enormous.

We are not even referring here to the software governed by the GPL, which generally have open source so that they can be analyzed, but in programs that generally add functionality to programs that already exist, such as programs that change the theme of your facebook page, or that at the time of MSN, they were exchanging various texts for emoticons on the user's screen.

Many of these programs are generally not just for the "fun" purpose, they carry a load of tasks from behind that the user doesn't realize.

How to have a more secure computer?

1. Always buy good software:

> Manufacturer's website

> Physical media, such as CD-ROM or DVD.

> Avoid pen-drivers and recordable / rewritable media.

2. Always try to have original software.

> Look for discounts in good stores to be more secure.

> Windows 8 Pro license costs on average R $ 250 and Office Student (enough for Word, Excel, Power-point) R $ 150.

3. Avoid downloading software as much as possible

> Doesn't your computer do that? Be content, rather your computer free and safe, fast and consistent, than a zombie from which you no longer respond to your commands.

> Look for alternative solutions, never if there is only one way to do what you need on the computer.

4. Look for online sites that do what you need without installing softwares

> I will go through a list below with recommended sites for each commonly desired item.

Many people can criticize me saying that I want companies to profit from licenses, but think about the following fact: Does anyone offer any good or product to someone for free, with nothing in return? No. So why do you insist on using programs to break the license?

Original software works better than cracked software, this is because they are operating with their legitimate programmed code, but from the moment it is cracked, other software is working together with this, both in terms of preventing you from losing your license as well as other purposes unknown.
