Do you want to know how to check a file has a virus before downloading? Continue with us throughout the whole article.

Common Problems:

1. External Source apps download

We often need to download some apps from external sources which are not listed or published in play store. When we download any apps, we can trust it well because Google Play verifies every apps with Google Play Protect security before publishing it in the play store. But the external apps, which you download from any websites or other external sources, can harm both your smartphone and computer. Hackers and spammers may hack or damage your device's hardware. They can use your stolen data for unauthorized activities. So when we have to download any apps from the external sources, we really fall in riddle and can't solve that we should download the app or not.

2. Large file download in Google Drive

When you try to download any file from Google Drive, Google automatically scans that that file for your security if that file is less than 100 MB. But, Google can't automatically scan any file uploaded on Google Drive if the file size is greater than 100 MB. So, hackers and spammers may upload any risky file which is more than 100 MB and send you to download the file because they know that Google can't completely scan this file for you. So, that may be a risky move for your device to download this type of large files without virus scan.

3. Want to scan mysterious files

We often download many type of files ( images, videos, pdf file, aia file, exe file, movies, songs etc ) daily and store it in our device's hardware and we often forget to scan. But, scanning is very important before downloading those files. Especially, I shall suggest not to download movies from unknown website because most of the websites upload risky files. Instead of it, you can watch movies on your smartphone or computer with a good broadband connection at home and it is much safer for your device.


4. App rejection on any app stores

Many times, the app stores reject your apps and decline your apps to publish in their app stores. In this case, it is necessary to check your app with a good virus scanner if it really contains virus or not. Virus may be found on your app if you implement any third party code on your app. But, I have seen that most of the Chinese app stores ( Such as - Xiaomi Get apps, Huawei App Gallery etc ) reject your app without any proper reason and they show a meaningless reason for your app like your app contains virus. Those Chinese app stores are not much believable and Google Play Store is much better destination to publish your app.
