3 Common Types of Malware

Malware is malicious software deployed against unsuspecting users for a number of nefarious purposes. Any device that connects to the internet may be vulnerable and potentially require removal of malware Odessa TX. Malware can be used to collect information about users, extort money, or just disrupt normal operations. There are many types of malware, but here are a few of the most common.


1. Spyware

Spyware is used to record keystrokes. They may be used to steal passwords as a way to gain access to people’s online accounts. A more ambitious use is to purloin someone else’s intellectual property that is created on the computer. However, sometimes spyware isn’t deployed by a stranger. Some people use it to keep track of loved ones’ computer activities. While the use may still be questionable, the motive is often sympathetic.


2. Ransomware

Ransomware has caused a lot of problems within the last five years or so. It works by encrypting the data found on the infected computer so that it becomes inaccessible. Then it demands that the user pay a ransom in cryptocurrency to remove the malware and get the information back. Without a validated backup, it can be difficult to reverse the damage. About 25% of victims pay the ransom, yet there is no guarantee that this will result in the release of the files. Targets of malware attacks are often essential services, such as law enforcement or hospitals.


3. Trojan

A Trojan gets its name from the ancient legend of the Trojan horse. Trojans appear to be harmless, legitimate files, but once downloaded, they execute malicious programming. A Trojan requires action by the end-user to work, which it accomplishes by tricking the user. For example, a website infected with a Trojan may cause a pop-up that looks like an alert from a legitimate antivirus program stating that the computer is infected and action is required.

Trojans are also used to execute ransomware attacks. However, not all Trojans are ransomware, and not all ransomware is delivered by Trojans.
