Windows 10: Weird behavior, possible Trojan
Weird behavior, possible Trojan
1. Volume icon appears with a red cross even though all sound devices are working.
2. With UAC set to default, a notification pops up at startup asking my permission to run explorer.exe
3. I can't run some programs.
4. Malwarebytes web protection suddenly disabled and can't be re-enabled. I'm using the latest one.
5. System restore fails all the time, so can't go that path either.
I suspect it is malware that targets/makes a fake explorer.exe, but not entirely convinced since there is only one instance and the CPU load is not constantly high. but I want to know if anyone has encountered this before and might point me int the right direction, like the name of the malware, perhaps.
Welcome to TenForums @frankmanguiob
Have you tried a scan with Malwarebyte Chameleon? If you are using 3, see:
Malwarebytes | Chameleon - Free Malware Removal Tool
There's also Defender Offline.
Windows Defender Offline Scan in Windows 10
Welcome to TenForums!
You can give this tool a try to see what it finds...
Please use the Farbar Recovery Scan Tool Download
Save FRST to your Desktop.
[Note: You need to run the version compatible with your system: 32 bit or 64 bit]
Double-click FRST to run it.
When the tool opens click Yes to the disclaimer.
Next, press the Scan button.
When done, the tool makes a log (FRST.txt) on the Desktop.
Also, the first time the tool is run, it makes another log: (Addition.txt).
Please attach both reports in your reply.
Note: FYI, MBAM v3 has experienced problems lately.
Thanks! Chameleon ran but it didn't detect anything. Defender offline doesn't work for some reason. I can't even view event logs.
Please see the attached.
My apology for the delay. Can't remember getting a notification of your reply.
Looked at the reports provided, and did not see malware.
You may want to run a System File Check on the OS:
SFC Command - Run in Windows 10
Use: Option Three
If you see: Windows Resource Protection found integrity violations
Then, please reboot, and run the sfc /scannow command again.
Sometimes it takes running the sfc /scannow command up to 3 times before all is fixed.
If no luck, and still looking at integrity violation, please use Option Five: To View Only the "SFC" Scan Results from the CBS.LOG
Next, attach the sfcdetails.txt in you reply for someone to look at.

The only reason I'm using Windows at all, (and not using Linux), is Windows is the only OS that's "handicap accessible" for people with my type of eye problems. I have very poor eyesight... and without the magnifier, I can't use the computer at...

First post here :)
Lately my Windows Defender is finding a Trojan in the Recovery D (Trojan:Win32/Dynamer!ac)
It only shows up after a full 3 hour search and not in the fast search
A full search with Malwarebytes, Adware and Hitman...
Just wonder if anyone has encountered these behaviors? It happens to me every time without exception:
If I do a restart, the computer restarts but makes the windows 7-start sound. Upon getting to the desktop, the laptop battery meter is missing...
