I get a notice from Microsoft Security Essentials that I have a backdoor virus in my backup zip files. backdoor:php/small.m I have run my antivirus multiple times on my wordpress site and it does not find anything, however, as soon as I download my backup zip files, I get a notice from MSE that one of the files has the backdoor:php/small.m virus in it?
Is this a false positive maybe, or do you think the virus is actually there? It appears to clean from the backup file, but then I don't know if the backup file is now maybe corrupted or not? Any help or suggestions on this would be helpful.
