                      Types of Malware

                      Here are some common types of malware:

                      Viruses

                      A virus is a type of malware that attaches itself to a program or file. When you open the infected
                      file, the virus spreads to other files or programs on your device. It can damage files, slow down
                      your device or even steal your personal information.

                         WinVer 1.4 was first Windows virus, Groove was first .exe file and Farooq Alvi brothers created first
                         boot virus.

                      Worms

                      Worms  are similar  to  viruses,  but  they  can  spread  on their  own without  needing  to  attach
                      themselves to other files. They spread through networks, often without any action from the user.
                      They can damage your files or network and slow down your device.

                      Spyware

                      Spyware is a type of malware that secretly monitors your online activity. It can track what websites
                      you visit, steal your passwords or collect personal information without your knowledge. Spyware
                      is often used for identity theft or stealing financial data.

                      Ransomware

                      Ransomware is a type of malware that locks your files or device and demands money to unlock
                      them. If your device is infected with ransomware, you may lose access to important files, such as
                      photos or documents, unless you pay the ransom (which is not recommended).

                      Adware
                      Adware is malware that displays unwanted advertisements on your device. It can pop up as
                      banners or ads, often slowing down your system. While not always dangerous, adware is very

                      annoying and can sometimes come bundled with other types of malware.

                      Trojan Horses
                      Trojan horses look like harmless programs or files but contain malicious code inside. When you

                      open or run them, they can steal your data, corrupt files or give hackers access to your device.
