A sort of malware the hackers use to attach to another program such as a document is known as a computer virus. A computer virus further circulates and duplicates once a person first runs that virus on their system.
For example, a hacker can send you an email that contains a malicious attachment. The virus will run into your computer unconsciously when you open that attachment. This virus could be a cause of destroying your data and further can slow down the speed of your system log keystrokes and resources.
If you think hackers develop a new virus every time, it is not true. Rather than creating new viruses, cybercriminals pay more attention to making more refined, advanced, and advantageous threats. There are different kinds of malware such as trojan, computer worm, virus, ransomware, or a couple of other dangerous things.
Android antivirus software is also known as anti-malware software. And it is a fundamental measure to prevent several threats. For example, a couple of them are going to make your Android smartphone crowd into irritating ads.
Another malware that is more dangerous and normally expresses itself as a certified application or website misled you by disclosing passwords and personal data, including financial information.
However, there is a lot of antivirus software available in the market; Malwarebytes for Android is one of the finest antivirus software that can protect your devices in the following ways:
- The first task it does is automatically find and remove harmful malware threats.
- Locates ransomware in your devices ahead of locking them
- To maintain the smooth running of your Android devices, it can offensively find Adware and Potentially Unwanted Programs (PUP).
- Whenever you utilize the Chrome browser, it scans for phishing URLs.
- It also performs a privacy audit for all the applications.
Examples of Computer viruses
Here in this article, we will explain a couple of examples of things that most of the people on the internet normally think are viruses, and we will let you know it is or isn’t.
According to different studies, trojans can be viruses. The computer software that hackers use to pretend as something not aimed at sneaking onto your device or supplying some malware is known as a Trojan. In other words, we will say it is a trojan if it hides. For example, it could be a file you downloaded from the web or a Word doc attached with an email.
Moreover, it would be best to have second thoughts before downloading your favorite movie from P2P or downloading tax documents from your accountant because they can contain viruses.
Worms are not considered viruses. However, the terms could be exchangeable. What is worse is that often the terms utilize collectively in a weird and conflicting word salad, for instance, a “worm virus malware.” It must be a worm or a virus; however, it can’t be both at the same time. And the reason behind the same is that worms and viruses indicate two equivalent but separate threats.
As you previously heard me say, a virus requires a host system along with some kind of action from a user to get spread from one system to another. However, it neither requires any host system nor some kind of action from any users regarding the worm. It can circulate over a network and any systems that are connected to the network. Worms basically drop malware (mostly ransomware) or open backdoors after getting onto your system.
Ransomeware is considered a virus. Ransomware blocks the access of the systems as well as private files. However, if users still want to access their data, they will have to pay ransom payments. These days the majority of ransomware appears because of computer worms that have the ability to circulate from one system to another and all over the network and do not even need any sort of user activity, for example, WannaCry.
A rootkit is not considered a virus. A software package developed by the cybercriminals to get the “root” access or admin access to a target system is known as a rootkit. It should be noted that rootkits can’t self-reproducing. That’s why they are not capable of spreading over the systems.
5. Software bug
Software bugs are not considered viruses. A defect or imperfection in a computer code is known as a software bug. The computer’s programs can act differently from their intended purposes if there is a software bug.
For example, let’s talked about Y2K. It is a computer bug that shows false dates, and the reason behind this is the program’s limited ability to handle dates through the year 1990. After 1999 the year capsized and sank similar to the odometer on an old car to 1900. Although the Y2K bug was not extremely dangerous, several bugs can be harmful to consumers. These bugs could provide illegal access to hackers to drop malware, collect personal data, or open backdoors in the targeted systems. This is called an exploit.

Different Kinds of Android malware
There are several kinds of Android malware. This article will discuss the top five kinds of Android malware.
An undesirable software that was developed to use for dropping ads on people’s screens while they use different web browsers is known as Adware. It normally utilizes a sneaky technique to hide as legal or pickaback of another program to deceive people in installing it into their devices, including mobile, PC, or tables.
Spyware is malware that is mostly used by cybercriminals to confidentially view the activities of target systems without their consent. After secretly observing users’ activities, spyware further reports them to the software’s author.
3. Trojan, or Trojan horse
A technique of attacking by showing itself as some kind of beneficial application or an attachment to push the users to download it into their systems. Trojan attacks have the ability to disguise anything from malware that permits the assaulted unlawful access to spyware that collects financial details.
In this technique, cybercriminals prevent users from accessing their devices by encrypting their files. Afterward, they demand ransom payments in order to get access to other systems and files. Furthermore, it is also known as the favorite weapon of cybercriminals due to its easy acquisition of online criminals’ marketplaces. The defense against ransomware is difficult, and it is most challenging when it comes to removal. That’s why the majority of the victims have to pay to get their data back.
5. Malicious crypto mining
Malicious crypto mining is also called drive-by mining or cryptojacking. This malware is becoming more and more widespread. A Trojan normally installs it. Cybercriminals use this technique to get access to the target systems to mine cryptocurrency, such as Bitcoin. After attacking, normally, hackers send the collected coins to their accounts. A cryptojacker basically takes the computing resources of targetted devices to make money. What makes it worst is that the targetted users don’t even know that they are affected, making them a specifically subtle threat.
