Malwarebytes is arguably the most popular secondary malware scanner. I have been using it for a year now, but recently I found out something which raised many doubts in my mind, so much that I decided to join this forum & start this thread.
Yesterday, while browsing though the internet, I unexpectedly downloaded a RAR file which contained something which looked like a folder.(But it wasn't) It was an exe, but it's icon looked like a folder & due to windows hiding known file extensions by default(Thanks Microsoft), .exe after the file name didn't appear. So to any average user, it would look like a folder. So after double clicking on it, i immediately realized that it was not a folder but an application. I decided to upload the file to virustotal. 44/55 detection, yup it's malware. Out of all the anti malware scanners to not detect it, I didn't expect malwarebytes to be one of them. The other 10 which didn't detect it aren't 'BIG' names in the anti malware business. I can't comprehend how I can trust malwarebytes now in keeping my device secure when literally every other major anti malware scanner was able to detect the file. I know anti malware scanners can't be perfect, but this is just too much.
Here's the VirsTotal link - https://www.virustotal.com/en/file/a23a02b39cbbb0c85c1022ee099783aed97b43d781cafe7d1881c17e49127caf/analysis/
Addional notes - That scan is 6 months old now, i can't rescan it because I deleted the file. But the point is, 6 months ago, MalwareBytes considered that extremely unsafe file as safe when no other major anti malware scanner did, so what's stopping that from happening again?
Since I'm not familiar with the security world, if something like this occurs with other well known malware scanners as well, I would certainly like to see a VirusTotal report where 40+ malware scanners flag a file but a well known malware scanner like Kaspersky/Bitdefender/Norton does not.
