Types of Viruses & Antivirus to Avoid Them

1. Basic virus

It is the simplest and oldest type of virus, created with the aim of hindering the operation of processor operating systems, slowing down their performance. You can also erase information stored on computers. Its arrival on the computer can occur through the downloading of programs that the system recognizes as safe. From this, the other types of malware that exist on the Internet are generated.

2. Trojans

After basic viruses, Trojans are the most famous group of viruses out there. Their strength lies in the fact that they achieve a level of camouflage that may go unnoticed by some versions of antivirus. It is a malware frequently used by programmers and is housed in various applications and files of the operating system. Mobile versions have even been created , where its effect can be much more lethal. It is linked to questionable email attachments, and unofficial license programs. It is fought with antivirus and antitrojans.

3. Worms

It is essentially a virtual virus, which can then stay on the computer indefinitely. Its favorite place is the RAM memory and it reaches it while we surf the Internet, managing to slow down the process. You can generate automatic replicas and travel through all the network systems that exist. It is controlled with antivirus and firewall.

4. Spyware

It is a more specialized class of virus, as it is basically a spyware. Its objective is to steal absolutely all the information on your computer and pass it on to its owner. It is one of the main avenues for the success of cybercrime.

It can be diagnosed when our default browser is replaced or when toolbars are installed whose presence we have not requested. They remain in our equipment because they are silently housed and are installed again when we turn on our equipment. To control it, you need a good antivirus, frequently update browser versions and, if possible, download their security add-ons.

5. Rogueware

It is a fake antivirus that is offered to us as a solution to detected threats. It is present in various environments for illegal downloading of files, adult content, free programs, etc. It is controlled by developing the security measures mentioned above.

6. Ransomware

This type of virus is much more specialized than the previous ones. It is designed to enter our computer and block it until the will of the owner of the virus is done. Generally, he is blackmailed into revealing passwords. It is recommended not to succumb to blackmail and to inform you properly about this threat.

7. Keylogger

It is aimed at recording, capturing and collecting all the keyboard movements performed by you regularly. They are accompanied by Trojans and can be installed not only digitally, but also through devices. Your goal is to steal information and blackmail.

How to avoid them:

1. Install a quality antivirus

Many people trust the free antivirus that come with Windows or Internet Explorer. However, these programs do not represent adequate protection against the growing list of digital threats. It is suggested to install professional grade antivirus on computers.

2. Install protection against real-time Trojans

Many users think that having an antivirus program that includes protection against Trojans and spyware (spyware) is sufficient.

3. Keep your antivirus programs updated

New threats to digital security arise every day, which is why updating our protection programs is mandatory.

4. Perform daily scans

Occasionally, a virus escapes the active protection of the antivirus and infects the system. Scheduling daily scans of the entire hard drive can prove invaluable in detecting, isolating, and removing harmful programs.

5. Disable the “Auto-run” or Auto-run

Some viruses operate by adding to external devices such as USB / Flash drives, External Hard Drives or Network Drives. Windows users can disable the auto-run function by following the instructions according to their operating system version.

6. Don't "click" on links in emails or attachments

Sometimes by distraction, users end up "clicking" on attachments they receive by email, even knowing that it is a risky action for their computers. Once this is done, the result may not be seen at the moment, but a virus or Trojan may be acting on the computer's memory, recording and stealing information.

7. Browse smart

Major browsers have protection mechanisms that notify us when we approach a potentially harmful website. However, it is vital to be careful when sharing personal information over the Internet. Always check if the page where it seems that we are is indeed trustworthy. Check if the URL is for the organization or company. Some hackers install web pages with an identical design to the original to confuse us.
