Safety Scanner found 12 infected files but scan results said no problems detected

Catwoman 36

I ran a Microsoft Security Scan and during the scan I could see that it had found 12 infected files. When the scan completed, it said that there were no viruses, spyware, or other potentially unwanted software detected. I have attached screen shots.

I also agree with the need for new wording on this tool. I was just doing a web search to see what sort of terrible virus was manipulating my AV software. I've been using 6 different tools for the last two days and these "infected" files kept me concerned.

I'm trying to scan. Immediately after scanning the system, it was found that some files contained viruses or malware. It immediately worried me. I don't know how many malware will be found when the process is finished.

I am encountering the same issue: Microsoft Safety Scanner 1.389.705.0 indicates Files Infected. The present count is at '2'. When I initially ran this scan the count was '14' (if I recall correctly). There where no recommended further steps recommended. 3rd party scanners don't indicate any infection but this is a Microsoft Operating System so I defer to Microsoft KB. Is my OS infected as Microsoft Safety Scanner 1.389.705.0 suggest or is Danny on point and some harmless code fragment has triggered these notifications? Kind of concerned since I had to return this device to the factory days after it's arrival due to an unauthorized web access and lateral movement.

Same problem here...I mean? What if the malware actually prevents the connection from happening in the first place? Then what the infected files stay. Time for MS to get there stuff together...anybody else noticed the vast amount of security updates? What is going on here?

Typical of Microsoft. You see, they understand the contradictory nature of the preliminary and final presentation of the results, so it is not necessary for the user to understand. This attitude permeates much of the "expert" intervention in threads on this forum and others when a Microsoft individual jumps in.

This particular issue cost me several hours as the scanner "discovered" twenty "infected" files. Further, would it not be good for the user to know what those infected files were, even if they were only suspicious? Then we could scan them with more comprehensive non-Microsoft security products. Microsoft, if you are listening, disclose those files and change your wording to reflect the truth of the situation. Have some respect for your knowledgeable user community out here, please.

If I wanted to play with horseshoes and hand grenades, I would pay a third party antivirus to detect nothing and call it something so they can charge me to fix the something that was nothing all along. Microsoft is claiming there is something that is actually something but they call it nothing. What, exactly is this scanner for? Maybe all the data you are collecting can be used to cure the Microsoft induced ADHD people are getting....

Ha, I had 224 "Files Infected" and then zero when complete. Had me supper worried as I use said computer for some work stuff. Then read answer below and felt much better.
224 is probably due to all the many many different device/controller connect, setup and control applications on it.
Why does every lighting, heating, building automation and control system manufacture have to have its own totally "unique" and most likely terrible application? Often a different one for each different line of any give product type they sell??

I have used the MS Safety Scanner for somewhere in the vicinity of 15 years. The scan reports always have stated what the OP describes. I have always had my suspicions that the scanner does find more and removes more malware than what it states. My desktop has been doing weird things for awhile. Slow. My ESET says everything is fine. I downloaded this scanner and let it work. It scanned overnight. In the am, scan is almost done finds like 25 issues. It ends and the report states nothing was found. But now, my desktop is back to its normal behavior. Apps start faster, switching apps is faster, weird links popping up in the address bar. All of that is gone. This scanner removed something. I suspect that there are more malwares in the wild than any of the IT people want to admit. This is just the MS way of removing them.
