Do you know when your browser filter or your antivirus says: this file can harm your computer ? Well, people began to understand that these are false alarm signals. Because of this problem, no one trusts the browser filter and the antivirus (for a good reason). The problem arose from the moment VirusTotal appeared. All security companies take their files from there, and this is something totally wrong, because the files are uploaded by users like you and me ! Antivirus teams are like sheep, if one says that a file is suspect, then everyone says that the file is a virus or suspect.
They do this so they don't lose the so-called "detection rate". That is why over ~90% of the files they detect as malware, they are in fact clean files, belonging to different legit software companies or belonging to you or me. So when your browser or antivirus tells you that the file "x" is infected, you should not listen to it. I've given up Google Chrome (mainly due to so called "malware" filters) and all antivirus software because these have told me that my programs (just compiled) were a threat to my computer. That is stupid, how can you interdict me to download my own statistical software because it might harm my computer ?!
