Actually, malware and virus are not types of another type of virus it is a term to identify the specific type of infection on our computer. If we talk about malware then there can be any type of threat in it, but if we talk about virus then we specify only a particular type of threat.
Malware stands for malicious software which includes all types of threats like – Viruses, Trojan, Ransomware, Backdoors, Rootkits, Worm, Adware, Spyware, Evasion etc. This malware has been designed only to cause harm or damage our computer system or our network system.

It steals data in the background without knowing the user even sometimes many antivirus or antimalware program not knows about it. Trojan horses not easily detectable but remove by best antimalware program.
Backdoors:- A backdoors usually a method which bypasses the normal authentication process over the internet connection and after a successful attempt it installs other backdoors or spyware to the system for future data stealing and this all process invisible to the user.

How many different ways our computer can be infected with the Malware
There are lots of different ways a malware coming into the computer, but some ways are very common to get virus or malware into the computer.
Downloading software from malicious sites
Most of the malware come in our PC from downloading software from an unauthorized site or malicious sites. Most of the time user downloads patches and crack of software from these sites and virus and malware is also downloaded along with it and when they install these patches or malicious software tools in computer, malware also installs and easily spread within the whole computer system.
Via USB or flash drives
USB is also most common reason when viruses get into your computer and through USB, viruses easily jump from computer to computer. Mostly Trojan horses or other types of spyware spread through USB because hackers design this malware to attach to one of the files in removable drives and it easily move one to another system.
Opening unknown emails or spammy links
If you ever see a link in your email which is unknown and saying to click on this link, maybe the link is spammy or it redirects you to an unknown site where the virus easily accessible to your computer. This type of emails created by hackers so that they can easily steal our data or put viruses to our system.
Visiting unknown sites on the internet
Visiting unknown sites or clicking on spam ads lead to redirect to other sites and asking for downloading the contents, these sites are present in all over the internet so only visit authority sites.
How do we know that our computer has a virus
When a computer infected by virus it gives many signs so we know that our computer is virus infected. If the virus changes some computer resources or our computer not working as usual so we should understand that this may be a virus infection.
Getting unknown error messages

Sometimes we work on computer and suddenly our computer freezes or got a BSOD Blue screen of death error this happens to many users and this error may occur due to incompatible software and hardware or any high severity malware. If you trouble with BSOD then I recommend you to check how to fix BSOD on windows.
Computer slower than usual
After a malware infection sometimes our computer slower than usual or got a message that “You are running out of space”. This may be happening because some malware uses high resources or high network traffic in our computer and if this happens through a malware then probably it runs unknown services and process in the background which you can easily find by task manager if the processes are not hidden.
Unfamiliar icons or wallpaper on computer desktop
Whenever you start your PC or laptop and see the unfamiliar wallpapers or icon on desktop and you do not remember or seeing before, then it highly chances that these things done by malware.
