Ways in which computer viruses are distributed?

Computer Viruses are commonly distributed through email attachments, where unsuspecting users may open infected files. They can also spread via malicious downloads from compromised websites or software. Additionally, removable storage devices, like USB drives, can transmit viruses when connected to unprotected computers. Social engineering tactics, such as enticing links on social media or deceptive ads, are also used to propagate these harmful programs.
