Remove “file contained a virus and was deleted” (Removal Guide)If you are seeing a “this file contained a virus and was deleted” message, when trying to download a program using Internet Explorer 8, 9 or 10, then your computer is infected with a ZeroAccess rootkit.

The ZeroAccess trojan is a dangerous threat that has been circulating for several years. In the time that ZeroAccess has been in the wild there have been a number of revisions, with modifications to its functionality, infection strategy and its persistence mechanisms on an infected machine. However, the core purpose has remained: to assume full control of the machine by adding it to the ZeroAccess botnet and to monetize the new asset by downloading additional malware.Primarily, Trojan ZeroAccess is a kernel-mode rootkit, similar in ethos to the TDL family of rootkits. It uses advanced techniques to hide its presence, is capable of functioning on both 32 and 64-bit flavors of Windows from a single installer, contains aggressive self defense functionality and acts as a sophisticated delivery platform for other malware.

Trojan ZeroAccess remains hidden on an infected machine while downloading more visible components that generate revenue for the botnet owners. Currently the downloaded malware is mostly aimed at sending spam and carrying out click fraud, but previously the botnet has been instructed to download other malware and it is likely that this will be the case again in the future.

The “program contained a virus and was deleted” trojan has been observed being distributed by exploits and programs that promote software-piracy, such as ‘keygens’ and ‘cracks’ (programs designed to bypass software licensing).
