What is spyware?
Spyware is a type of malicious software that is installed on a user’s computer without their knowledge. It is used to collect confidential information, such as passwords and credit card numbers, and send it to a third party. Spyware is often bundled with other software, such as freeware or shareware.
Some spyware programs are difficult to remove, as they may modify core files or registry entries. Anti-spyware software can detect and remove most spyware programs, but some spyware is designed to specifically evade detection.
Spyware can be used for a variety of purposes, such as identity theft, data theft, and system sabotage. In some cases, spyware may be installed without the user’s knowledge in order to collect their confidential information. In other cases, spyware may be installed for malicious purposes, such as to track a user’s online activities or to display unwanted advertisements.
There are a number of ways to protect yourself from spyware. First, only download software from reputable sources. Second, install an anti-spyware program and keep it up-to-date. Finally, be careful when clicking on links or opening email attachments, as these can be used to install spyware on your computer. Click for source
What is a firewall?
A firewall is a system designed to protect a network from unauthorized access. Firewalls can be either hardware- or software-based, and are typically configured to deny access to all services except those that are explicitly allowed.
Firewalls are often used to protect private networks from the public Internet. By blocking all incoming traffic that is not specifically allowed, firewalls can help to prevent malicious or unwanted access to the network. Additionally, firewalls can be used to protect individual computers from attacks by other computers on the same network.
While firewalls are an important part of network security, they are not perfect. Firewalls can be bypassed, and they cannot protect against all types of attacks. Additionally, firewalls can sometimes block legitimate traffic, which can be frustrating for users.
Still, firewalls are a valuable tool for protecting networks and computers, and are typically used in conjunction with other security measures, such as virus scanning and intrusion detection.
