In today’s world of Information Technology, we enjoy a lot of benefits with the increasing rate of technological advancements and on the other hand, we also have to face some threats to our computers and one of them is different types of computer viruses which is a specific type of malware.
Before going in-depth on our main topic it is necessary to know what is malware? as computer viruses are a type of malware. Macro Viruses are used by hackers in a great number in order to steal, destroy, or modify data from another person’s computer. I want you to follow along till the end of this article carefully in order to get to know about it in detail.
1. What are malwares and what do they have to do with Viruses?
A virus is a specific kind of malware and in order to know about Viruses, we first need to know what is malware actually. Malware means all the programs that are written with malicious intent in order to steal another person’s important data or cause mischief to it.
There are a lot of different types of Malwares but here we are going to discuss only one specific type of malware called Viruses.
2. What is a Computer Virus?
A computer virus is actually a malicious program codded by a hacker with bad intentions for performing different suspicious activities like destroying important data and stealing important information.
It can also download some other type of malware depending upon how is it coded and for what purpose is it coded. It also has a unique trait of replicating itself without even letting it know to the user and could be easily spread among a lot of computers.
3. Types of Computer Viruses
Generally, there are a lot of different types of Computer Viruses but they are all not necessary to be discussed here. I’m going to discuss some of the main types of computer viruses that are necessary to be known by you.
There are the following main types of computer viruses:
i. Macro Viruses
Macro Viruses are viruses that are written in Macro languages like VBA(Visual Basic for Applications) that are mainly platform-independent.
The malicious programs written using these languages can run on any platform and can also make forced attacks for performing different functions that the computer won’t allow without the administrator’s consent.
Microsoft Office is an example of the applications made using VBA(Visual Basic for Applications).
ii. Stealth Viruses
Stealth viruses are such types of viruses that usually try to hide any modifications made by them and then try to trick the antivirus software by providing false and bogus information so that they can’t be detected easily by the antivirus software and continue their suspicious activities.
iii. Polymorphic Viruses
It is such a type of computer virus that produces varied operational copies of itself and such a virus may have no paths that remain identical between infections.
This makes it very difficult for the antivirus software to detect directly using signatures and they can be really dangerous for our important data.
iv. Self-Garbling Viruses
Self-Garbling viruses are such types of viruses that attempt to hide from antiviruses by modifying their code that does not match pre-defined antivirus signatures.
These are the types of viruses that simply spread from one machine to another. One of the unique functionality that differentiates it from other types of viruses is that it can make copies of itself and deliver such copies to other users or another computer via different means i.e. via emails.
vi. Boot Sector Virus
It is such type of computer virus that damages or controls the boot sector on your hard drive. This type of virus is usually spread using USB drives and it is activated when such an infected USB device is plugged into the computer and the computer is booted.
4. Taking proper preventive measures is the best cure
Yes, the best way is to prevent such virus attacks by taking all the necessary precautionary measures which are:
- Avoid opening any unnecessary documents and emails which do not concern you at all and you should better delete them.
- Install advanced antivirus programs and make sure that they are up to date and keep them updated with time.
- Operating Systems like Mac and Windows have built-in various security features and programs that can protect your PC from different cyber attacks.
- Keep your computer updated by installing up-to-date security patches that are being issued by the creator of your operating system.
- Most important of all is to take every step carefully and do not do things over the internet, especially that can lead to installing Virus on your pc i.e. We should take proper care while downloading any file or software and try to know that if it is actually the file which you wish to download or is it something else and if you are not sure about it I’ll suggest you to not download it at all.
The more advanced the technology is getting and growing the more complex and difficult it is getting to protect ourselves from different cyber attacks. Different types of viruses are usually the programs that are written with malicious intent. They can steal your important data or even cause more harm to you if they are not prevented properly or stopped.
The best way, to protect ourselves from any type of viruses or any other security threats and vulnerabilities, is to take proper preventive measures and deploy complete security policies that can make it difficult for viruses to cause harm or breach.
