kevinf80 Posted October 8, 2020 ID:1412657 Share Posted October 8, 2020 Hello UsagiChan37 and welcome to Malwarebytes, Run the following: Download Farbar Recovery Scan Tool and save it to your desktop. Alternative download option: http://www.techspot.com/downloads/6731-farbar-recovery-scan-tool.htmlNote: You need to run the version compatible with your system (32 bit or 64 bit). If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version. If your security alerts to FRST either, accept the alert or turn your security off to allow FRST to run. It is not malicious or infected in any way... Be aware FRST must be run from an account with Administrator status... Double-click to run it. When the tool opens click Yes to disclaimer.(Windows 8/10 users will be prompted about Windows SmartScreen protection - click More information and Run.) Make sure Addition.txt is checkmarked under "Optional scans" Press Scan button to run the tool.... It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply. The tool will also make a log named (Addition.txt) Please attach that log to your reply.

kevinf80 Posted October 13, 2020 ID:1414029 Share Posted October 13, 2020 Hello UsagiChan37, I do not see any malware or infection in the logs from FRST. The original query you quoted regarding Antimalware Service Executable is not really a problem, that is a service for Windows Defender. More than likely the high CPU reading occured during a scan. Has the high CPU settled down...? Thank you, Kevin.. Link to post Share on other sites More sharing options...
UsagiChan37 Posted October 14, 2020 Author ID:1414139 Share Posted October 14, 2020 What can i do to identify my problem? Here is the screen that Antimalware Service Executable reach 30% My pc is slower than before, but i don't have so much programs or files Link to post Share on other sites More sharing options...

kevinf80 Posted October 15, 2020 ID:1414465 Share Posted October 15, 2020 Run FRST one more time, ensure all boxes are checkmarked under "Whitelist" but only Addition.txt under "Optional scan" Select scan, when done post the new logs. "FRST.txt" and "Addition.txt" Link to post Share on other sites More sharing options...
kevinf80 Posted October 17, 2020 ID:1414903 Share Posted October 17, 2020 Any progress...? Link to post Share on other sites More sharing options...
UsagiChan37 Posted October 17, 2020 Author ID:1414911 Share Posted October 17, 2020 Yes, sorry, here are the new files FRST.txt Addition.txt Link to post Share on other sites More sharing options...
kevinf80 Posted October 17, 2020 ID:1414913 Share Posted October 17, 2020 Download attached fixlist.txt file (end of reply) and save it to the Desktop, or the folder you saved FRST into. "Do not open that file when running FRST fix" NOTE. It's important that both FRST and fixlist.txt are in the same location or the fix will not work. Open FRST and press the Fix button just once and wait. The tool will make a log on the Desktop (Fixlog.txt) or the folder it was ran from. Please post it to your reply. fixlist.txt Link to post Share on other sites More sharing options...
UsagiChan37 Posted October 17, 2020 Author ID:1414919 Share Posted October 17, 2020 Ok, here is the file, but i checked task manager and antimalware was at 21% for now, what problem is this? Fixlog.txt Link to post Share on other sites More sharing options...

kevinf80 Posted October 18, 2020 ID:1414940 Share Posted October 18, 2020 (edited) Hello UsagiChan37, Looking at the errors in FRST logs Windows Defender is not being allowed to finish an auto scan. That maybe the cause of high CPU.... Try the following: Offline scan for windows 10 Open the search function, type or copy/paste Windows Defender Security Center then select ok to open that option. In the new window select Virus and Threat Protection then select Scan Options The scan options window will open, from there select Windows Defender Offline Scan You will be given the option to save any opened work etc, then select Scan from there when the scan completes Windows will reboot.. To check for found entries: Select Start , and then select Settings > Update & Security > Windows Security > Virus & threat protection . On the Virus & threat protection screen select Protection history. If entries are shown as "Found" the time and date will be same as the offline scan just completed..... Thank you, Kevin Edited October 18, 2020 by kevinf80 typing error Link to post Share on other sites More sharing options...
UsagiChan37 Posted October 19, 2020 Author ID:1415089 Share Posted October 19, 2020 Okay, i did the Windows Defender Offline Scan, but when i go to Protection history, there's no completed scan on 18/10/2020 (because i did a scan yesterday) Link to post Share on other sites More sharing options...
kevinf80 Posted October 19, 2020 ID:1415106 Share Posted October 19, 2020 Probably nothing was found, do you still get raised cpu readings for "Antimalware Service Executable" Link to post Share on other sites More sharing options...

kevinf80 Posted October 19, 2020 ID:1415154 Share Posted October 19, 2020 Select the Windows key and R key together, the run box will open. Type or copy/paste services.msc into the run box, tap enter.... Services window will open. Scroll to Security Center.... Right click direct on that service, select Refresh.. Close out the services window, reboot your PC... Does the issue with "Antimalware Service Executable" clear..... Link to post Share on other sites More sharing options...
UsagiChan37 Posted October 21, 2020 Author ID:1415641 Share Posted October 21, 2020 I did it, but nothing has changed Link to post Share on other sites More sharing options...
Solution kevinf80 Posted October 21, 2020 Solution ID:1415657 Share Posted October 21, 2020 Ok, try the following: I`ve attached WinDefend.zip to this reply, download and save to your Desktop, unzip that file so you now have WinDefend.reg Double click on that .reg file, allow any merges or alerts. When complete reboot your system, does the issue clear.... WinDefend.zip Link to post Share on other sites More sharing options...
