Virus Checker by davidpolitis on 10-04-2006 at 05:33 AM
Sorry if this question has allready been asked but I was wondering if someone could make a script that checks the name of a file that someone is sending you & uses a website to check if it could possibly be a virus or spyware/adware. (Sorry for not being very specific)

Hi,
Why do u want to have that ? Windows Liv e Safety Scanner is free and you can download it from the settings window of WLM. Go to File Transfers tab and then click on Install. It is downloaded and installed directly by WLM ...
See you
NB : Maybe you wanty something else, don't know ...

1. I can't Install Windows Live Safety Scanner for some reason &
2. Doesn't Windows Live Safety Scanner scan the files after downloaded?

How can it scan the file if the file hasn't been received?

Files are scanned after they are downloaded, but before they are executed. Just downloading a file won't get you infected anyway, you have to execute the code somehow.
quote:Checking files on filename is a very bad way to check for badware, anybody could simply change a filename. And even if it would be a good method, maintaining a site and keeping it up to date with all the latest threats just takes too much work for normal people.

I suggest to just a normal virus scanner, which not only scans files send on Messenger, but all the files on your PC.

I use Bitzi to check the "bitprint" of a file, gets around the file name changing thing
If we could make a script that reads MD5 strings, that'd be good

quote:By design, but it is possible for a vunerability in the scanner to be exploited to excute code in the file when it is scanned. Vunerabilities like this exist not only in virus scanners, they can be in filesystem drivers, productivity applications and other programs that even look at a file.
