You're missing a call to binmode(), which is essential for reading and writing binary files under Windows. You're also trying to read a binary file into an array of lines. Binary files don't really have lines, so this won't work. Even if they did, you can't be sure your checker can identify a virus by looking at just one line of a file, so you'll have to be able to match across arbitrary sections of the file.

On a higher level, a virus checker can't really work by loading the entire file into memory - some files you'll have to check won't fit in memory!
