In English we put the following phrases below software we want customers to download to put their mind at ease (for example, a neat weather app).
- ✓100% virus free
- ✓Contains no malware
- ✓Contains no spyware
- ✓Certified adware free
- ✓This file is clean and safe
etc.
What is an equivalent phrase in Japanese (not literal translations, but a phrase actually used in practice)?
Something like "✓ウイルス等が検出されませんでした", but more optimistic and reassuring.
Note: Searching for a live example has proven fruitless as Google searches lead to anti-virus software, not "clean" downloads.
