I had infections like babylon, delta and similar
In C:/programdata/temp folder I have 4 postbuild.exe files, of different dates.
no program like Ccleaner or malwarebytes deletes them
1) how they , postbuild.exe files, orginate?
I guess that they might be related to cyberlink programs like powerdvd10 or power2go (this last one I have deleted) but I am not sure.
2) can they be malware?
3) can I 100% safely delete them? is a good idea to just rename them and if there is nothing strange delete them then?
