How To Fix Virus not detected in Avast & MBAM, but detected when I upload the file to Gmail

TIP: You should click here to fix Windows errors and optimize system speed.

Disk related errors are often the main cause of the File System Errors in Windows operating system. This mostly can be attributed to issues like bad sectors, disk integrity corruption or other related problems. With a huge software system like Microsoft Windows that is designed to perform an extremely large number of tasks, errors that concern the file system is to be expected at some point.

Some of these errors can also be caused by third party softwares, especially those that depend on Windows Kernel in order to run. Common users can also trigger such file errors with heavy use.

From the Forums

A user in the forum details it further:

I downloaded an icon pack APK file on my computer to upload to my mobile. Anyway, the thing is, when I double clicked on it, BlueStacks (Android Emulator) opened up, and Avast started giving me lots of warnings about BlueStacks accessing Trojan URLs (it blocked them of course).   Now, the thing is: I scanned the APK file both in Malware Bytes Anti Malware and Avast (and even Malware Bytes Anti Rootkit), and it showed no virus or malware found. And more importantly, (though I have deleted the APK file in question from my computer) is my computer safe? But when I try to attach the the same APK file as a Gmail attachment (which I read on the net detects viruses, which is why I tried it), Gmail gives me a "Virus found" error.   So, my question is how come such reliable antivirus / anti-malware programs like MBAM and Avast didn't detect the virus but Gmail did?

Or has a rootkit / trojan been installed? Upload file in question here: for security check. I did a stupid thing yesterday.

What causes Virus not detected in Avast & MBAM, but detected when I upload the file to Gmail

Most of these file errors can be fixed easily by applying the most recent software updates from Microsoft. However, sometimes, certain type of errors can be hard to repair.

For the more complex file system error issues, common solutions include the following:

  • Resetting Windows
  • Doing system file maintenance repairs
  • Clearing the Windows Store Cache
  • Repairing Component Store
  • Reinstalling Windows Apps

You can also use the System File Checker tool in order to fix corrupted and missing system files. Meanwhile, Check Disk chkdsk can also be used to verify file system integrity and to locate bad sectors on your hard drive.

Avast files detected as malicious by MBAM

I hope this is a false positive

Malwarebytes used to detect itself as malicious, so this isn't as surprising.

Note the detections, other than the PUP there are temp avast files which are malicious.

Tough virus not detected by MBAM

Oh, and it just disabled Windows Defender on the latest boot (not that it was helping anyway).

The other offending files that it created are hidden too (except in WinRAR) and can't be deleted either.
Somehow I got MBAM to scan once, and it found the other files the virus created, but not the original psr.exe that's still unremovable in my Downloads folder. Restarting however resulted in the virus coming back and uninstalling MBAM.
Trying to run DDS got me the attached screenshot. There's no option in the properties to stop it from running in compatibility.

MSE Causing BSOD and MBAM not removing detected file

If I run MBAM is safe mode, it works and finds one file (below) infected. That missing file could be causing BSOD's. here is a link to my other post about the BSOD issues:

Someone had the same problem this morning and it was a false alarm.>

Right click Malwarebytes and select run as administrator. Then run Malwarebytes again and see if it shows clean.

it says it removes the file but if I restart back into safe mode and run the scan again, the same file comes back. If it finds something again click Quarantine option not delete. let me know if there is anything else that you may need from me. Once open click update tab and do so.

Any help is greatly appreciated. Then click the Quarantine tab next to the Update Tab. This will put the file back in place. c:\Windows\winsxs\amd64_microsoft-windows-wininit_31bf3856ad364e35_6.1.7600.16385_none_8ce7aa761e01ad49\wininit.exe (Trojan.FakeMS) -> Quarantined and deleted successfully.

There evidently is a glitch that has been fixed for false positives. If your Trojan file is listed there click restore. I think it was a false positive. Mike

I am not sure what to do with this, but it seems to be causing MSE to frequently BSOD. That is the only way I know to find out. basically MSE is constantly stopping, and if I try to run MBAM, I get ...

Virus that is not detected by malwarebytes/avast

The last time i tried to remove a virus on my own, my machine ended up being crashed and i had to do a full wipe. I was wondering if someone could remote in and help me? Neither malwarebytes nor avast has detected it. I have a virus called 'Pc Performer', that keeps popping up and doing a virus scan and prompting me that there are errors and that i need to buy, and blah blah blah.

None of them have worked either. I not only need this virus removed, but the fact that it keeps coming back needs to be investigated. I've also tried security check, combo fix, and ccleaner.

I've actually had this virus before and this is the 4th time it's came back. I have teamviewer so i need some remote help.

Avast! detected mqsv32.exe as a virus?

In the "File to upload & scan" box, browse to the location of the suspicious file and submit (upload) it for scanning/analysis.Prevx's Investigation Report of the file "mqsv32.exe"What did avast do with that file?

However, it then places itself in a different location (folder) than where the legitimate file resides and runs from there. Another techinique is for the process to alter the registry and add itself as a Startup program or service so that it can run automatically each time the computer is booted. One of the ways that malware tries to hide is to give itself the same name as a critical system file.

What is that file and is it safe to delete it? Anytime you come across a suspicious file or one that you do not recognize, search the name using Google <- click here for an example.If you cannot find any information, the file has a legitimate name but is not located where it is supposed to be, or you want a second opinion, submit it to Jotti's virusscan or VirusTotal. Determining whether a file is malware or a legitimate process sometimes depends on the location (path) it is running from.

avast! detected virus, unable to delete

aswMBR will create MBR.dat file on your desktop. I did a bootscan with avast! to delete the virus and then I did another scan again, yet the virus has not been removed. This computer is bought and mainly used by my father and he's not tech savvy at all. I will do a scan with MBAM tomorrow as I do not have MBAM installed in this computer right now and will need to copy it off my computer back at home.

This computer freezes randomly. This is a copy of your MBR. The virus is Glupteba-B, Adware-gen, Malware-gen and Rootkit-gen.

Do NOT delete it.

Threat Detected during Avast! scan, log shows no virus found

Running automatic scans once a day and am having a couple of issues:
 About once a week I will get a “Threat Detected” pop-up window post-scan, but when I click on the “Show Results” button it does not work, and when I look at the “Scan History” button and look at the scan it always shows “No Virus Found”.  This pretty much sums it up:
After each daily automatic scan Avast! Opens a pop-up window showing that the scan was run, even though I have turned off having the pop-up window (when nothing is found) via the Avast! Settings.
This problem occurs on a Dell XPS 8500 desktop running Windows 7.

MBAM detected something

MBAM detected some trojan virus and a backdoor virus?
When I started my computer, a pop-up came up saying Run or Cancel application from the source I think, Users/app roaming/dscvhost.exe I think. After I system restored MBAM couldnt update and I went to uninstall mbamclean.exe and install a clean copy and worked to update again.

Run a quick scan with MBAM and post the log.

I then system restored my computer and scanned my computer again, nothing showed up. So I am not sure if my computer still has infected files or not. I am not sure.
