Antivirus deleting my client application

1 May 2011 by Sandeep Mewara

Instead of trying to add it to a Antivirus safe list all by itself, you should look at why it's being considered a virus. Thus instead of removing the cause you are trying to hide it out. For me as a client, not agreeable at all. For me, it's like a malicious software for me that I would...

Attachment of Email sent from c# is detected as virus and is deleted

19 Jan 2012 by Sergey Alexandrovich Kryukov

Well, you cannot predict how crazy every particular anti-virus could go. One practical advice would be to zip all the files to be added as attachment (only if you can), but this won't really guarantee that the attachment is not removed by the antivirus. Antivirus tools used at the level of...

can changing file's file extension protect your computer?

7 Feb 2012 by Jonathan [Darka]

A virus can infect any file which can be executed, the file extension is not important.Each executable file can be identified no matter what extension you give it, if your proposing a whole new executable format then that would be a whole lot of work....Additionally, changing the...

can changing file's file extension protect your computer?

7 Feb 2012 by Manfred Rudolf Bihy

I'm afraid that is not going to happen. A file can be opened and analzed by a virus to discover it's true purpose. Most files contain some headers that betray to the virus what they really are. For example by renaming a dll or an exe file to a file with a txt extension it could still be found...

SHA1 Hashes - like all other hashes - are a number which is generated from a block of data, and you can't identify a virus by using an SHA1 hash...

I don't think there's a free public database available. There were attempts to start a free and open source virus signature DB but they all got abandoned. It's a very expensive task to keep it updated since new viruses and trojans are detected on a daily basis (sometimes multiple times daily).

Why creating yet another virus scanner, especially MD5. It will be two weak. Who will want to use it? It will depends on the database of known signatures and won't detect polymorphous viruses. It will give false sense of security to some, which is worse than not using anti-virus at all. Can you...

21 Apr 2011 by OriginalGriff

You need to talk directly to the antivirus companies, and find out why their product incorrectly identifies yours as a virus. It may be that you have accidentally incorporated a virus signature in your exe, or your application may exhibit virus-like behaviour. Only they can help you there!

22 Apr 2011 by Nish Nishant

You may be able to convince some of the anti virus companies (perhaps they'll need you to sign your applications). But eventually there will always be some anti virus packages that will identify your app as a trojan/virus.This is because many of the things a parental control app has to do,...
