Weiß jemand wozu die Datei MSHTA.EXE im Windows 98SE
Systemordner gut ist?
Mein Virenscanner behauptet, daß sie möglicherweise einen
Virus enthält.
Kann ich die einfach löschen ???
Bringt´s was wenn ich die einfach umbenenne ?_
Die Datei wird mit dem IE5 installiert. Es ist ein HTML-Programm, das HTA-Dateien ausführen kann. Da hierbei evtl. sämtlich Sicherheitseinstellungen des IE umgangen werden können, ist nicht auszuschließen, dass dadurch schädliche Programm geladen und ausgeführt werden können. Kann gelöscht oder umbenannt werden, ohne die Funktionalität des Browsers einzuschränken (glaube ich).
Habe in einer Security-Seite folgende (engl.) Informationen gefunden:
HTA (HTML Applications):
_An HTA is an HTML-based webpage file, with .hta file extension. Through the use of webpage scripting, in combination with functionality provided by Internet Explorer 5, it’s possible to create programs of a sort that run in the IE5 browser window.
If IE5 is installed an .hta file is opened by MSHTA.EXE, thereby bypassing all browser security. The only security limitation on an HTA is that it must be downloaded. Other than that an HTA is the equivalent of an installed program and can do anything that any installed program can do, without needing any special permissions. An HTA webpage will download ActiveX controls, if necessary, without informing the user, regardless of browser settings. In a sense, HTA is little more than a method to shut off all security restrictions in your browser.
HTA is a useful invention in controlled circumstances, such as on a closed network. Unfortunately, as with so many other things, you’re not given the choice of whether to enable HTA. If you have IE5 then you’re HTA-capable. That’s partly why there’s currently an epidemic of email viruses. The vulnerability to HTA, combined with inadequate (default) IE5 security settings that enable scripting, allows for a virus to be transmitted through Outlook and OE5 email simply by reading the email. No file attachment is necessary. The recent viruses KHA.HTA and KAK.Worm are good examples of this problem.
While the file association for opening .hta files can be changed to Notepad for better security, the safest approach might be to delete or rename the file that provides HTA functionality: MSHTA.EXE in the Windows/System folder. ( In WinME this is a protected file that can only be removed by uninstalling PCHealth.)_
