When this infected program is executed or loaded by the operating system, it will also execute the viral code which may perform any number of functions including disabling security protections, destroying files, displaying messages, slowing down computer performance and sending personal information about the user to remote servers where they can be stolen.

A trojan horse functions like a virus but instead of being inserted into an executable file such as EXE, they are disguised inside another program’s data file typically posing as some form of useful software for example; anti-virus software.[] Rootkits are similar in that they modify system settings without permission or notification so that malicious actions cannot be stopped by standard antivirus products.
