Malware, short for malicious software, is a blanket term for viruses, worms, trojans and other harmful computer programs hackers use to wreak destruction and gain access to sensitive information.

Malware is a catch-all term for any type of malicious software, regardless of how it works, its intent, or how it’s distributed. A virus is a specific type of malware that self-replicates by inserting its code into other programs.

The primary difference between a virus and a worm is that viruses must be triggered by the activation of their host; whereas worms are stand-alone malicious programs that can self-replicate and propagate independently as soon as they have breached the system.

Usually, a worm is more dangerous than a virus, because it can spread more quickly. For example, a worm could infect all of your email contacts. Worms can also spread without notifying you or interacting with you at all, such as through a security vulnerability.

A virus must meet two criteria: It must execute itself. It will often place its own code in the path of execution of another program. It must replicate itself.

Blaster Worm., the worm has been designed to tunnel into your system and allow malicious users to control your computer remotely. A Trojan horse is not a virus. It is a destructive program that looks as a genuine application. Unlike viruses, Trojan horses do not replicate themselves but they can be just as destructive.

It’s designed to steal your account information for all the things you do online. That includes banking, credit card, and bill pay data. This Trojan targets instant messaging. It steals your logins and passwords on IM platforms.

Trojan-IM programs steal your logins and passwords for instant messaging programs – such as WhatsApp, Facebook Messenger, Skype, and many more. This type of Trojan can allow the attacker to control chat sessions, sending the Trojan to anybody on your contact list. They can also perform DDoS attacks using your computer.

Summary. Virus:Win32/Xpaj is a family of viruses that spread by infecting local files and removable and network drives. The virus attempts to download arbitrary files which may be detected as other trojans. It may also arrive on your computer via a drive-by download.

All of these malicious programs can cause serious problems including data and financial losses. If your anti-virus software has detected Trojan. Win32. Typically, these malicious programs are disguised as harmless and legitimate software – people are usually unaware that their computers are infected with them.

VirTool:Win32/DefenderTamperingRestore is a type of malware that is programmed to stop your security software from working correctly. While the initial goal of this virus is to compromise security software to bypass its defenses, cybercriminals behind it may have various goals.
