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.

How to say "100% virus free"?
ウイルス等が検出されませんでした sounds more like "No virus were detected", which is different
from "Virus-free".

The first thing I'd like to mention is that most sophisticated Japanese
e-commerce sites do not say anything like this in their download pages, at
least in a large font. To me, saying "virus free" loudly already smells like
typical foreign sites (some of which are actually risky) built by non-native
speakers of Japanese.

That said, perhaps the most natural wording would be "ウイルスチェック済み" (lit. "virus
check performed"), "マルウェア・スパイウェアを一切含んでいません" (lit. "contains no
malware/spyware"), etc.

Some sites do say something like "複数のセキュリティソフトで検査した上でソフトを公開しています" ("We host
software after checking it using more than one security solutions") in a
relatively small font.

Using a word なし seems to be a common way in Japanese, if a company or a
developer team provides this kind of information.

For example, [a Japanese webpage about a software called AOMEI
Buckupper](http://www.backup-utility.com/jp/free-trial.html) uses this
expression.

> 100％クリーンのインストール： スパイウェアなし、アドウェアなし、 **ウィルスなし** ！ご安心ください。

In [the English webpage of this](http://www.backup-utility.com/free-
trial.html), it says

> 100% Clean Installation: NO SPYWARE, NO ADWARE, NO VIRUSES! Please set your
> mind at rest.

As shown, literally, it’s a little different from your phrases, but I think
the purpose is the same, so hope it helps.

Some websites use 無し instead of なし. For example, [a webpage about Avant
Browser](http://www.avantbrowser.com/default.aspx?uil=ja) uses the following
expression.

> 広告無し、 **ウイルス無し** 、スパイウェア無し、マルウェア無し！

So, a phrase actually used in practice is ウイルスなし or ウイルス無し in many cases.

If you’d like to know more, please try some Japanese version websites of other
softwares. Their translation may be helpful.
