What is a Runtime Virus?

A runtime virus is a type of malware that infects a computer system during the execution of a program or application. Unlike other viruses that trigger upon startup or system boot, runtime viruses only activate when the infected program is running. This makes them difficult to detect and allows them to stealthily compromise the system.

 Common Types of Runtime Viruses

There are several types of runtime viruses, including:

1. File infectors: These viruses attach themselves to executable files and spread when the infected file is executed.
2. Macro viruses: These target specific applications, like Microsoft Office, by infecting macros and spreading through document sharing.
3. Script viruses: Often found in web applications, these viruses exploit scripting languages like JavaScript or VBScript to infect systems.

The Causes: How Do Runtime Viruses Infect Your Computer?

1. Malicious Emails and Attachments

One of the most common ways runtime viruses spread is through malicious emails and attachments. Unsuspecting users might click on an email attachment or a link within the email, inadvertently launching the virus.

2. Infected Software and Downloads

Downloading software or files from untrusted sources can also lead to runtime virus infections. This includes pirated software, unauthorised downloads, and files from suspicious websites.

3. Removable Media

Inserting infected USB drives, external hard drives, or other removable media can introduce a runtime virus to your computer.

4. Social Engineering Attacks

Cybercriminals may use social engineering tactics, such as phishing, to trick users into executing a runtime virus. These attacks often involve posing as a trusted entity to deceive users into taking action.
