First, "1tamilmv" sounds like a domain or a website. I know that there are sites offering Tamil movies for download, often using similar names to avoid detection. The term "madraskaaran" is Tamil for "Modern Style," which makes me think of the Indian actor Vijay's movie "Mudrasaarakaran" (2016). Maybe "Madraskaaran" is a mix of "Mudrasaarakaran" and "Modern," possibly a new version or a similar title for 2025.
