It steals user’s information and misuses them to fulfill malicious purposes.

It is challenging to detect spyware. Therefore, users must install anti spyware software on their system for prevention and protection against such attacks. The anti-spyware software identifies the threats based on either specific rules or downloaded definition files.

An anti-spyware program is a highly recommended security measure for any computer user.

It runs in the background and continuously checks for the presence of any spyware and other malware programs on the system.

When detected, it alerts the user and lets the user quarantine or remove the infected files, directories and registry keys. Anti-spyware functions in different ways, which are discussed below.

Hard Disk Scan

Spyware usually leaves a signature in the operating system’s registry. A hard disk scan by the anti-spyware program effectively helps in finding out any spyware existence on the system.

It uses a database having known sets of spyware, and searches all the files on the device for matches. The larger the database employed in an anti-spyware software, the better is its chances of detecting spyware.

That’s why, anti-spyware software is frequently updated to include the new spyware in its database too, and thus help to protect the user’s system. Usually, it is available on a subscription basis.

Registry and Memory Scan

For Windows systems, a registry scan determines the changes made by spyware to the Windows configuration files. It is also an excellent technique for anti-spyware to figure out malware in the system.

A memory scan checks the processes running on the computer to discern any suspicious activity.

Monitoring URLs

Monitoring the URLs is a prevalent method for anti-spyware to figure out spyware attack on a system. They keep track of websites visited as well as monitor cookies against a database of known spyware.
