The latest antivirus software features many protection options for your computer. But do even know what you are protected against? Know the 9 major threats against you below.
Malware is an umbrella term for malicious software which can do anything from steal data to bypass access codes. A virus spreads by attaching itself to an existing file and copies itself from there, much like a biological virus. When a user executes the program it activates . Rendering advertisements, creating botnets, and many other malware symptoms can be experienced because of a virus.
A bot is a software program that automatically performs a specific operation. If your computer is infected with a bot, then it is probably part of a botnet. This is a network of compromised computers controlled by third parties. If your computer is infected with a bot, then it most likely used for malicious activity like DDos attacks. CAPTCHA tests in websites help guard against bots.
3. Trojan Horses
This malware type disguises itself as a normal file that tricks users into downloading and installing it. Once a computer is infected, the attacker is given access to sensitive data like login details and bank information. A Trojan can monitor activity through keylogging and even use the system in a botnet.
Advertising-supported software, as the name suggests, is delivered through advertisements. Many free versions of software come with adware which is mostly annoying but harmless. Adware is generally harmless but the inclusion of spyware make adware a potentially dangerous platform to introduce other malware into your system.
Spyware can do a variety of things. Activity monitoring, like keystroke logging and data harvesting, are the most common spyware attacks. This type of malware can also do more malicious things like modify security settings and interfere with network operations. Spyware typically gets introduced into a system with Trojans.
This very dangerous type of malware can remotely access computers and control operations without the users knowing it. Rootkits can alter software, especially the very programs that are supposed to detect rootkits, and install malicious software or create a botnet. Rootkits require manual removal because of the stealthy nature of this malware.
This is by far one of the common types of malware that can infect a computer. Worms use up bandwidth and also have payloads or pieces of code that perform actions other than spreading the worm in the system. Payloads can steal data, delete files, and create botnets. Worms act like viruses except for one crucial difference: they do not need a user to manually run a program for it to spread.
As the name implies, this type of malware demands a ransom before certain key functions will be returned to the control of the user. For instance, restricting access, encrypting files, and system lock downs will stay in place unless a payment is made to regain access.
A bug is a flaw that creates an undesired outcome. Bugs are usually within the source code and a result of human error. Many bugs just affect certain programs but more problematic ones can cause serious problems like computer freezing and crashing. Security bugs are the most malicious as they bypass user passwords, program privileges, and outright steal data.
