Windows task manager (more details), "startup apps" crash on view

[mhaz]

hello,

This seems to be a similar issue to https://forums.malwarebytes.com/topic/250372-windows-task-manager-closes-after-clicking-on-more-details/. 
MalwareBytes (incl. rootkit scan) finds nothing now although in previous checks it found *both* CPU64  AND Win32/Wacatac.B!ml; based on the symptoms and the identical previous finds, I'm sure it's the same issue.

Current scans all return clean (as well as Norton's and Windows Defender's) but I'm still unable to open the "more details" tab in the task manager as well as "Startup Apps" without that window crashing.

I've found and installed FRST but without the specific fixes, could really use your help. Happy to run any/all diagnoses on my end; I'm eager to get rid of this problem. 

Thank you!

Hello mhaz 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.html Note: 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... When you`ve downloaded FRST64.exe, rename it to FRST64English.exe...   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. Thank you, Kevin..

thank you, Kevin! I was able to resolve the issues by accessing and manually deleting the registry keys that were related to the malware startup items, based on instructions here:
https://www.windows-commandline.com/delete-registry-key-command-line/

everything works great now. That said I do greatly appreciate your help and hope this thread might be useful to folks running into the same issue. Thanks again.
