I'm using Windows 7 Ultimate x64, with Norton 360 v5.0. Windows as well as Norton is updated daily. But I get this message, titled "Remove the TrojanDownloader:Win32/Adload.DA virus from your PC", with "Windows has detected , a known virus, on your computer." in Action Center. I scanned with Microsoft Safety Scanner as mentioned in the action details, tried MalwareBytes, apart from Norton 360, but none of them detected any malware. I also do not experience any of the symptoms mentioned in http://www.microsoft.com/security/portal/threat/encyclopedia/entry.aspx?Name=TrojanDownloader%3aWin32%2fAdload.DA (like the folder/files with name opencap can't be found).
Whenever any program crashes (I use some legacy programs designed for Windows XP or Flash Player update), the Action Center report shows that the reason for the crash is because of the Trojan. The crash is also not frequent and causes hardly once a month. But if it happens once, the message is displayed and stays for one day to at most five days.After that, "No current issues detected" is displayed.
Does the Trojan by the name actually resides in my PC or is it a fake alert?
Also,does Windows detect virus/malware by itself?
