We 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 or others browser then your computer is infected with a ZeroAccess rootkit.
Don't panic. You can solve it very easy way .
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.
Her is the Solutions:
Rename Windows Defender folder to stop the “file contained a virus and was deleted” notification .
Click on the Start button, select Computer, click on Local Disk (C:), and the click on Program Files.
In the Program Files folder, right-click the Windows Defender folder and select Rename from the context menu.
Add a unique variation to the filename, such as .old or panic (for example, Windows Defender.old, Widnows Defender.panic) or something.
-- Cheers !!!
