Digital Security Issues: Malicious Software, A Virus

 I think my telephone has a type of malicious software that makes me believe that my cell has a virus. Sometimes, it will fool me into believing that my security measures are old. In turn, they offer new updates for my security settings. So I do not know what to do.

This Link is to a page for solutions

9 Tips to know is your mobile phone have a virus:

  1. Excessive data usage: Undetected viruses running in the background of your phone may significantly increase data usage.
  2. Unauthorized charges: Some forms of trojans may drive up your phone bill with in-app purchases and text charges to premium accounts, which hackers can then collect on.
  3. Apps crashing: Apps may repeatedly crash if your mobile software is compromised. Before searching for a virus and assuming the worst, check that your storage isn’t full and you don’t have too many apps running simultaneously.
  4. Unusual search engines: Many people have a primary search engine they use for search queries. If your searches are being answered by new or unrecognizable search engines, this could be a sign that a virus has infected your phone.
  5. Pop-ups: While some pop-ups are a normal function of advertising while browsing the web, if your browser is closed and you’re experiencing increased pop-ups, you may be experiencing adware, a type of malware whose goal is data mining.
  6. Increased battery drain: You may experience an inexplicably quick drain on your battery with the increased use of your phone’s RAM if a virus is running in the background.
  7. Unrecognizable apps: When you see unrecognizable or fake apps that were mysteriously downloaded, they may be malware. Trojan horses can also attach themselves to legitimate applications and cause further damage.
  8. Overheating: Malware can consume RAM and CPU quickly, causing your phone to overheat. While occasional overheating may be normal, a chronic issue could be a signal that there’s something more dangerous afoot.
  9. Fraudulent linking: Malware may gather sensitive data and attempt to infect your contacts by sending dangerous links and attachments through texts, emails or social media messages.


Antivirus software is the most fail-safe way to protect your mobile phone from viruses, and the most famous method.

Clear the Cache. The first item on your checklists is your browser. If you visited some suspicious pages, some data will still be stored, navigate to settings and selects Apps & notifications. Next, find your browser of choice (in our example Google Chrome), go to its storage and select Clear Cache.

Reboot the device. Press and hold the power button, when the dialogue box appears, choose reboot to activate "safe mode".

Find suspicious Apps. Open your settings. Select Apps. Tap See all apps and enter Installed apps in the drop-down menu. Manually review applications to find any suspicious downloads. Once identified, open the app information and uninstall or force close it. After this step, you can restart your phone like normal.

Enable Play Protect. The most secure way to protect an Android against a virus is by installing an antivirus, but Play Protect can be used as a secondary protection measure. To enable this built-in software, enter the Google Play Store app and open the menu under your avatar. Choose to activate Play Protect so it can scan your device for security threats.

Digital Security Issues: Use the Same Password Always

 I always use the same password for all my accounts and applications. I do not like to use complicated passwords because it is difficult to remember and too long. What do you think?

This link is to a page for solutions.

Using the same password for all your accounts is extremely risky. Is have poor security and one service can compromise all.

Is better to Writing in paper or in a notebook, that can you see is it necessary.

You can save your passwords with your Gmail accounts. That you have your passwords in the Gmail accounts.
Or you can use more longer password and simple that you can remember.

Another is to use a Manager of passwords to remember and generate strong passwords. That the only password that you need to remember is the password to the Manager of passwords.

Other alternative to Manager of passwords is to use a Algorithm, by "Algorithm " i mean a set of rules that you use each time you create a password, that you can use to remember all the passwords.

For example:

  • The first three letters of the site URL for which you are creating a password
  • The first three characters of the name of your first pet spelled backward
  • Your age on your birthday in the year 2010 + a number like 333
  • Three characters indicating what the site is about – perhaps “ban” for bank, “ema” for email, and so on – with the first letter capitalised.
  • If the service requires it, a special character at a standard location. Perhaps a “#” the end.
According to those rules, my Gmail password might be "goons386Ema#"

Build a computer: Case

General information

The PC case is only the a fancy-looking box that holds all the PC's components. It have pre-defined areas with screws and holes where all of the components are supposed to be placed and attached to.

PC case come in different colours, and sizes, some have RGB lights, some don't, some have glass panels another no.

In another words a PC case is a box with buttons and ports of USB, HDMI,etc… you don't actually need a case. Another people put the PC components in the floor or on the table. But haven't a case is more difficult to transport the PC.

The most popular case are the NZXT H500 or the Phanteks Enthoo Pro

Photos of the case NZXT H500:

Build a computer: CPU

General information

 The CPU is plugged in the motherboard's socket, every CPU is has a specific socket, and the motherboard will need the exact same socket to be compatible with the CPU.

The fist step is to choose the CPU to choose a motherboard with be compatible.

CPU means Central Processing Unit and it processes any task you might throw it. Without is the computer is no functionally.

Everything you doing in a computer will have to be calculated by the CPU, you need a fast CPU (high frequency and high core count) will make your PC faster.

The most famous CPU are AMD Ryzen CPUs and the Intel CPUs

Build a computer: Motherboard

General information

 The motherboard case is a printed circuit board that every other hardware and components is attached. It like a central HUB that connect and manages all, the motherboard has connectors that cables like power cables, etc..slots for cards like RAM, GPUs, etc..

There are also lots of little building blocks like transistors, capacitors, jumpers, etc... all go towards making the different hardware and PC components work well together.

The most popular motherboard are the MSI PRESTIGE X570 CREATION and the Gigabyte Z590 Aorus Master.

Build a computer: CPU Cooling

General information

 The CPU cooling is necessary because the CPU generates a lots of  heat, this means that they need to be  cooling, to be able to operate flawlessly.

Some CPU's like many AMD's Ryzen Series already have CPU-Coolers included in the box, but someone like the Intel i9 CPU's, do not included.

Make sure that you have a CPU-Cooler that is compatible with the CPU and the socket, there are two popular types of CPU-Cooler. One is the Air-Cooled Tower Cooler and the other is the an AIO (All In One) Closed Waterloop CPU Cooler.

Here is a Photo:












AIO Closed Waterloop CPU Cooler tend to do a better job at a cooling overclocked CPU's and that run hot for longer periods.

A good cooler to the Intel i9 is the ARCTIC Freezer 34 eSports DUO.

A good cooler to the AMD Ryzen is the cooler that is go in the box of the AMD Ryzen

Build a computer: GPU

General information

 The GPU purpose is to processing of anything that has to do with visuals and outputs these visuals (Images, User Interface, GUI, Video) onto the monitor(s).

There are two main types of GPUs, the integrated GPU (IGPU) and the discrete GPU.

The integrated GPU is integrated into the CPU. This means some CPU's already have a graphic chip built-in and you will not need an additional Graphic Card to drive your Monitor.

When your CPU has integrated Graphic chip (such the Intel i9 13900K CPU) you can connect your monitor to the display adapter on the Motherboard. 

They are good enough for light tasks such as word processing and some light gaming. Still, as soon as you want to dive into graphic-heavy tasks such as 3D GPU Rendering, Higher-End Gaming, Video Editing, Graphic Design, you will want a discrete GPU.

The most famous GPU are the RTX generation such as the: RTX 3060 TiRTX 3070, or the higher-end RTX 4090.

Or the AMD generation AMD Radeon RX 6800 or the AMD Radeon RX 6800XT.

Build a computer: RAM

General information

 The Random Access Memory (RAM) is the "shortest-term" memory part of the computer if you would compare it to a brain.

The RAM is the stores data that is actively being worked on by the CPU. RAM can read and write data extremely fast (much faster than any permanent storage solutions) but can't retain information once the power is turned off.

RAM kits consist of RAM Modules such as the 4 colourful Modules you can see in the image above.
You can get just one Module, 2 Module, 3 Module, 4 Module, or even 8 Modules and more as long as your Motherboard has sufficient RAM Slots.
A Motherboard has RAM  Slots where RAM gets plugged in to. RAM comes in differences capacity starting around 4GB and going up to 64GB per Module on modern systems. Having more Modules, of course, will multiply your RAM capacity.
Find out what RAM performs best for your future PC build, and take look at our guide to see how much you'need.
This a example of a Ram of 64GB:

Build a computer: Storage (HDD/SSD/NVME SSD)

General information

 The storage (HDD / SSD / NVME SSD) is to store thing without electricity because the RAM hasn't store thing without electricity.

There are 3 typical mass-storages types:

  1. The HDD (Hard Disc Drive)
  2. the SSD (Solid State Drive)
  3. NVMe SSD (Non-Volatile Memory Express Solid State Drive)
The main difference between the 3 are is the speed. An HDD is the slowest of the three and will usually read and save Data at about 100 MBytes/s. An SDD will already read and write at around 500MBytes/s. An NVMe SSD currently reads and writes sequential Data with up to 10000 MBytes/s.

Both HDDs and SSDs are plugged into a SATA connector on your motherboard via a SATA Cable. They also need Power that they get through a SATA Power Cable from the PSU   (Power Supply Unit).
The NVMe SSD, though, is plugged into the motherboard directly, it is about as small as a stick of chewing gum and is no needs cable. Your Motherboard, of course, has to support NVMe SSDs and have an M.2 slot available. But almost all modern Motherboards nowadays have at least one of these. Highly recommended!

Build a computer: More Cooling

General information

 We talked about the CPU Cooling a bit already. The CPU isn't the only PC components that needs cooling  in a computer.

The GPU, too, needs cooling, but every discrete GPU that you can buy already comes with an attached heatsink and cooler on top of it, so we don't have to worry about extra cooling for the GPU. Now, because the PC case is usually closed shut, and the PC components inside the case need coolish air to not overheat, there should be a way to blow colder air from outside of the PC's case into the Case.

This is done by attached Case fans to the inside of the case These then pull in cool air at the front of your PC and blow the hot air out the back of the PC, creating so-called airflow throughout the case. This way, the inside of the PC-Case and all of your PC Components ideally stay nice and cool and performance isn’t reduced through things such as thermal throttling.

Here is a size comparison:


Usually not, as most cases are shipped with extra fans that will do just fine for this purpose. If you are thinking about building an extraordinarily quit/silent PC, though, you might want to get higher-quality case fans than what is shipped by default with a standard case.

Build a computer: Power Supply Unit

General information

 The most important components of your PC is the Power Supply Unit (PSU), because is you don't have a PSU the PC isn't work, because didn't have power to light.

There are so many PSU brands, PSU tiers, and efficiencies with different wattages out there that it can be quite difficult to decide which one tu buy. The important thing how much wattage your current PC Build will need to run stable and possibly how much you will need in the future if you are planning on adding more components, like extra or stronger GPU's or Storage.


 We recommended buying a stronger PSU that will later also be able to handle any upgrades, if you are unsure of how much wattage your current or future PC Build actually needs head on over to the Wattage Calculator that tells you exactly how much you need.

Some great PSU that I can recommended without hesitation are the CORSAIR RMX Series RM650x and the  Seasonic FOCUS Plus 650 Gold.

Build a computer: Display Device (Monitor, Keyboard, Mouse)

General information

 Any PC that you want to interact with needs a display device such as monitor, to be able to see what's going on. Monitors come in all kinds of sizes, colours, resolutions, aspects ratios, and so on.

A popular modern display usually is a  24” or 27″ Full HD/4K Monitor from brands such as Asus, Dell, LG, BenQ, Samsung, and many others. If you are looking for a Gaming Monitor, you might not need IPS-Type Panels but rather a TN Panel Display with better color display and contrast.


IF you are into visually-demanding workloads such as Graphic Design and professional Color Grading or Video Editing, you should invest more money into a good monitor, the Monitor is attached to either the discrete GPU or the Motherboard’s display connector, depending on what type of GPU you have.

Don’t forget a good Mouse and (mechanical) Keyboard, because you need a Keyboard to write document, to search in internet or to play video games, and a Mouse to move mouse around the screen and click in the things.

Build a computer: Operating System

información general

 Windows 10 es el sistema operativo líder en la actualidad que te permitirá utilizar tu PC. Muchas tiendas en línea ofrecen claves de licencia por volumen que no cuestan más de 15 € por licencia.


Windows 11 también está disponible, pero aún está plagado de errores y no es compatible con todo el software, por lo que no todos se animan a actualizar. Por supuesto, deberá instalar el sistema operativo en su computadora, y hay varias formas de hacerlo. Puede usar un DVD de instalación del sistema operativo Win si tiene uno y su PC tiene una unidad de DVD. Sin embargo, hoy en día, como las unidades ópticas se están convirtiendo en algo del pasado, el sistema operativo generalmente se descarga directamente de Internet (para que usted cree su propio medio de arranque en DVD o unidad USB), o puede comprarlo en una memoria USB (Thumb-Drive) desde la que puede instalar Win10/11.
