Can a malware download itself?
Yes. You can. Most viruses spread via email, where once the host is infected, the virus sends copies of itself to all email contacts, and all the contacts download it manually, not knowing it is a virus, and so on.
How does malware install itself as a service?
Many worms spread by infecting removable drives such as USB flash drives or external hard drives. The malware can be automatically installed when you connect the infected drive to your PC.
How does malware propagate?
Malware spreads in computer when you download or install an infected software. They also enter your computer through an email or a link. Once malware enters the computer, it attaches itself to different files and overwrites the data. As malware travels within the network, it infects the computer it moves into.

How does a malware inject code into a process?
Instead of injecting code into a host program (e.g., DLL injection), malware can perform a technique known as process hollowing. Process hollowing occurs when a malware unmaps (hollows out) the legitimate code from memory of the target process, and overwrites the memory space of the target process (e.g., svchost.exe) with a malicious executable.
What kind of malware attaches to another program?
A virus is malware that attaches to another program and, when executed—usually inadvertently by the user—replicates itself by modifying other computer programs and infecting them with its own bits of code. Worms are a type of malware similar to viruses.
What’s the difference between a virus and a malware?
Macro viruses usually arrive as Word or Excel documents attached to a spam email, or as a zipped attachment. Fake file names tempt the recipients to open the files, activating the viruses. An old but still prominent type of malware, macro viruses, remain popular with hackers.
