4. What are those viruses that activate at specific time?
Viruses that activate at specific times or on specific dates are known as time-triggered viruses or time bombs. These viruses remain dormant until a predetermined date or time, at which point they activate and execute their malicious payload. Here are some well-known examples and characteristics of such viruses:
Examples of Time-Triggered Viruses

6. What are worms and how do they affect computer?
What Are Worms?
A worm is a type of malware that replicates itself to spread to other computers, typically without any user interaction. Unlike viruses, which attach themselves to other programs or files, worms are standalone programs that can spread independently. Worms exploit vulnerabilities in operating systems or software to propagate through networks.
How Worms Spread
- Network Connections: Worms often spread through network connections by exploiting vulnerabilities in network services or protocols. Once a worm infects one computer, it can scan for other vulnerable systems on the network to infect.
- Email: Some worms spread by sending themselves as email attachments or links in phishing emails. When a recipient opens the attachment or clicks the link, the worm activates and begins spreading.
- Removable Media: Worms can also spread via removable media like USB drives. When an infected drive is inserted into a computer, the worm copies itself to the new system.
- Exploiting Software Vulnerabilities: Worms often take advantage of security flaws in operating systems or applications to spread. For example, they may exploit unpatched vulnerabilities in web servers, databases, or other networked applications.
Effects of Worms on Computers
1. Network Congestion
- Description: Worms can generate significant network traffic as they scan for and infect other systems.
- Impact: This can slow down network performance, leading to congestion and reduced availability of network resources.
2. System Resource Consumption
- Description: Worms often consume substantial system resources (CPU, memory, bandwidth).
- Impact: This can degrade the performance of infected systems, causing slowdowns and crashes.
3. Data Corruption or Deletion
- Description: Some worms are designed to corrupt or delete files.
- Impact: This can result in data loss and disrupt normal operations.
4. Unauthorized Access and Control
- Description: Worms may create backdoors, allowing attackers to remotely control infected systems.
- Impact: This can lead to data theft, further malware installation, and the compromised system being used for malicious purposes.
5. Propagation of Other Malware
- Description: Worms can act as a delivery mechanism for other types of malware, such as viruses, trojans, or ransomware.
- Impact: This can amplify the damage by introducing additional threats to the system.
6. Financial and Productivity Losses
- Description: The damage caused by worms can lead to significant financial losses due to downtime, data recovery efforts, and loss of productivity.
- Impact: Organizations may incur costs for repairing infected systems, recovering lost data, and implementing enhanced security measures.
Notable Worm Examples
1. Morris Worm (1988)

4. Network Segmentation
- Description: Divide the network into segments to contain the spread of worms.
- Benefit: Limits the impact of an infection by isolating affected segments.
5. User Education
- Description: Educate users about the risks of opening email attachments, clicking on links, and using removable media.
- Benefit: Reduces the likelihood of user actions that could introduce worms.
6. Email Filtering
- Description: Implement advanced email filtering to block malicious attachments and links.
