Windows 10: Microsoft Anti-Malware Signature Package scan disappears results of scan

I ran Microsoft Anti-Malware Signature Package with a full scan after my taskbar began to malfunction and my Settings kept blinking off immediately after opening. During the scan the thing showed "7 infected files" message but upon completion it said "no viruses found". So I have no log or anything to find the bug. The text flies by after "currently scanning" so I cannot read it to guess where to look for infected files.I am running Windows 11Version 10.0.22621 Build 22621Using Microsoft Safety Scanner 1.391.1196.0 Screen grab is from 3rd try ....

Super slow malware scan

The speed and ability to complete an anti-virus or anti-malware
scan depends on a variety of factors.

• The program itself and how its scanning engine is designed to scan: using a signature database vs heuristic scanning or a combination of both...see
  
  How an Anti-virus Program Works.
• Options to scan for rootkits, adware, riskware and potentially unwanted programs (PUPS).
• Options to scan memory, boot sectors, registry and alternate data streams (ADS).
• Type of scan performed: Deep, Quick or Custom scanning.
• What action has to be performed when malware is detected.
• A computer's hard drive size.
• Disk size and used capacity (number of files that have to be scanned).
• Types of files (.exe, .dll, .sys, .cab, archived, compressed, packed, email, etc) that are scanned.
• Whether external drives are included in the scan.
• Competition for and utilization of system/CPU resources by the scanner.
• Other running processes and programs in the background.
• Whether the scanning engine stalls, hangs or freezes.
• Interference from malware.
• Interference from other security programs attempting to scan at the same time.
• Interference from other programs attempting to update (download/install) components from the Internet.
• Interference from the user (whether or not you use the computer during the scan).

To speed up a scan,
clean out temporary (junk) files first,
temporarily disable any other real-time protection tools, close all open programs, perform a
Quick Scan instead of a Full one and do not use the computer during the scan. You can also speed up a scan by using file exclusions...What
Files Should You Exclude?.

Generally there are three types of scans offered by most anti-virus and anti-malware programs:

• Quick Scan only checks the areas of your computer most likely to contain malware...the most prevalent and common places where malware typically hides. The length of time for performing a Quick scan will vary but it generally takes about
  15-30 minutes so they can be performed daily.
• Full Scan is much more comprehensive since it scans the entire hard drive (all folders/files) which can number in the thousands. The length of time for performing a Full scan will also vary but because it is so comprehensive, this type
  of scan can take several hours. Most Full Scans can be scheduled to run late at night when not using the computer so you can perform a weekly scan without having to monitor it.
• Custom Scan allows the user to select any files and folders on the hard drive to be scanned.

In most cases when performing routine security checks, only a Quick Scan is needed since it checks the areas of your computer most likely to contain malware...the most prevalent and common places where malware typically hides. A
Full Scan is much more comprehensive and can take a long time since it checks the entire hard drive (all folders/files) which can number in the thousands. The length of time for performing this type of scan varies because it is so comprehensive
and therefore can take several hours. As such, a Full scan is generally recommended only for heavily infected systems...showing obvious indications (signs
of infection and
malware symptoms) that something is wrong.

Note: Using two or more program security scanning engines at the same time can cause each to interfere with the other, cause systems hangs, false detections, unreliable results and other unpredictable behavior. Some files and services are
locked by the operating system or running programs during use for protection, so security scanners may encounter problems attempting to access them. Other legitimate files, especially those used by security programs, may be
obfuscated, encrypted or password protected in order to conceal itself so they do not allow access as a protective measure. Further it is not unusual for an anti-virus or anti-malware scanner to
have problems with or be suspicious of
compressed,
archived,
.cab,
.rar,
.jar,
.iso, and
packed files because they have difficulty reading what is inside them. These kind of files often trigger alerts by security software using

heuristic detection because they are resistant to scanning (difficult to read). This resistance may also result in some scanners to stall (hang) on these particular types of files.

 

How long to scan based on software and hardware

Depends on the type of scan, the number and kinds of files, and the performance of the drive. I've seen scans take 4-6+ hours before. Quick scans usually run closer to a few minutes. Let it run its course. I always enable MBAM and other software to inspect containers (ZIP, RAR, 7Z, etc), and to perform deeper scans, even if it takes substantially longer.

Do you know what malware you've been hit with?

What are you running as your live AVAM (Anti-Virus Anti-Malware) scanning solution? Windows Defender? Or is your MalwareBytes a Premium version?

 

Microsoft anti malware tool

I have attempted several full scans using the malware anti malware tool. I have never been able to get a result. One scan lasted 36 hours indicating 12 infected files. Then it crashed. What am I doing wrong?
