I have come across an issue on two different laptops.
I run some software for astrophotography and one of the 'suites' calls a .bat file on start up. Quite often it fails to start the applet (Cyqwin) with two or three "Bad Image" errors always relating to certain .dll files.
I go and look at the .dll files and they state they are 0 bytes in size. I made backup copies of the files and just copying the backup copies over the corrupted ones fixes the issue... for a while. Sometimes a day or two, sometimes an hour or so. Always the same the .dll files are reverted to 0 bytes.
I have scanned both machines with Windows Defender, McAffee, Malware bytes in 'normal' and in safe mode. None of them report any suspects on either machine. I also ran Avast on one laptop and it too came up 'clean'.
I have tried going through the registry and clearing out any keys to Cygwin and re-installing. Again it works for a little while then later 0 byte files.
I am at a loss here and hope someone might be able to help with this.
ps; I am new to these forums, I hope that this is the proper sub forum for this sort of issue.
Oh yea I guess I should mention this is Windows 10 64 bit
