Chrome already protects us from malware and phishing sites that are part of the Safe Browsing feature, with the release of Chrome 17, Google added Chrome protection against malicious downloads which checks files downloaded through Chrome’s download manager against the list of known bad files, also checks executable files with .msi, .exe, .dll or bat extensions. I’m going to tell you what you should do when you download a file from a trusted site that’s been around for so long that Chrome flags it as malicious.
When Chrome warns you with a red danger icon with text like example.ext looks malicious showing ‘Discard’ button, you can Discard it from saving to your computer immediately or you can keep this file by clicking the little arrow next to Discard and selecting ‘Keep’, remember that you should only do this if you trust on the site where you downloaded the file from.
If you’d rather keep it than dismiss the warning,
1. Visit Total virus website and upload the downloaded file for a scan marked as malicious by Chrome, if you go all yellow for the detection rate (one or two reds treat as false positives) then you can treat the message shown by Chrome as a warning warning.
2. Don’t make any changes, right click on that file and scan that file with antivirus on your computer and then with Antimalware like MBAM to feel confident that the file is safe to run on your computer.
Today when I tried to download the newly released app from a website I’ve known for a long time and covered several apps launched by them here, Chrome detected and alerted this file as malware. We may neglect this warning in this case because this app was recently released.
