So they changed a hard-coded file path, and a hard-code service name, ya know, the kind of things that antivirus could look for? Yup, couldn't possibly be the same people, I've authored or co-authored about 10 pieces of software, and I never change file paths or service names...
I never cared about Kaspersky because I run the hardened, server-grade, no-need-for-antivirus OS known as Linux on my home PCs, but if Kaspersky thinks that it couldn't possibly be the same virus because 2 arbitrary file names were changed, then I'll come right out and say that Kasperky are idiots.
