I've been infected with the trio virus mscvhost.exe, huelar.exe and winlogos.exe. It began when I opened a hidden yet very suspicious folder with an ".exe" attached and I opened it by accident and now the virus has spread. Unfortunately, my AVG was currently expired (BAD mistake not to replace it).

Ok, so I did something of course. Because task manager and regedit was disabled, I worked on that first by using USBSCAN and killed the processes. Ok so far it appeared clean. But when I looked into HijackThis for a scan, there was a file there that said "O4: Startup: mscvhost.exe"

ONLY HijackThis had detected it. Taskmanager and Process explorer shows no such name running on its processes. I tried searching it on regedit and in a regedit safe mode to no avail. I even tried system restore (which was useless considering the update was just after the virus came in) and run the cmd using inputs I've copied from a source but I was unsuccessful.

The problem with my computer that's killing me is the fact that all files and folders in the My Computer have a display size of 91.5kb and all of it are applications. When I try to open one, the virus replicates and restores the trio virus on the taskmanager and the folder is generally empty. That's when I know it's still there, hiding itself very very well.

My brother said mscvhost.exe is an automated virus hid by some "root -something-" program... But I don't know how to remove it without using another computer!

I can't think of anything else to do how to get rid of this loathsome virus. Due to its persistence, I've been thinking if there are other viruses involved other than those trio...? i hope not.

Does anyone know how to get rid of it other than what I've already tried?

Ok so I cleaned up the viruses first by Hijackthis and only mscvhost.exe remains. It can't be deleted because I have to kill the process by the taskman itself but the problem is, taskman or even the process explorer doesnt say there's any mscvhost.exe there. So how can I delete it?

Here is the data by Hijack this:

I tried editing the registry with the help of rootkitrevealer for the path address and some other source and I found some huelar-related viruses. I edited those. But there's a file I couldn't open because it was "access denied":

HKEY_USERS\S-1-5-21-343818398-1580818891-1708537768-1003\Software\Microsoft\Windows\CurrentVersion\Shell Extensions\Approved\{AC7E2FD9-C772-34DD-BE21-3FA1D990D30E}

Rootkitrevealer hangs when it comes to a registry file so it doesn't finish the scanning. Usually it comes up with 4-5 output, 3 which are 0 bytes and other non-huelar related rootkit. The "Help" section of rootkit was also disabled.

All efforts...dumped.
*groan*
--PLEASE BEWARE OF THIS VIRUS--
mscvhost.exe, huelar.exe and winlogos.exe
...and some pesky rootkit protecting the mscvhost.exe, (a Kernel rootkit I suppose) hiding very well inside the registry.


If you come across a folder with an ".exe" attached to it, (especially when there's only ONE folder and the others are all viruses) DO NOT OPEN THAT FOLDER. IT'S A PANDORA'S BOX. If it's my paranoia working, I'd say I'd reformat that USB or device right away.

This is what happened before my laptop took an early retirement:

I'll list the steps so someone will take some moral out of it, or maybe just be AWARE. It's a pain not to be aware.

1. I booted the laptop

2. First thing I checked the accessibility of the task manager & the regedit, something I did out of habit and paranoia after my laptop got infected (4 days ago)

3. They were untainted, so I ran HijackThis and found the ever present "O4: Startup: mscvhost.exe"

4. I had a new program download called "autoruns" by systernals, so I ran that and it also found mscvhost.exe on a folder, but can't friggin delete it.

5. So next task:
I'm finally installing a good Antivirus to settle it all (or so I thought): NORTON ANTIVIRUS 2009
I set it up and had it running to do a FULL SYSTEM SCAN

6. After 5 hours of scanning, it came up with 78 HUELAR.EXE VIRUSES and 1 TROJAN HORSE VIRUS, all under the HIGH risk. It was fully deleted/removed.

7. Then, also out of sheer habit and dependency, I checked HIJACKTHIS. It wouldn't run because the computer said "It was already running." I CAN'T find it on the tray, whatever. Maybe it's under the rug, I don't know. The thing is, it's not there.
Well, I FIGURED it was the AV's fault. You know, 2 AV running at once is a heavy load even to a laptop.
I contented myself instead to checking Autoruns and was not disappointed: as I saw it, the folder virus NO longer existed.
YEHEY, my mind rejoiced. But because I felt uneasy about my dear hijackthis not functioning, I decided to restart the laptop.

8. On reboot, just when it's about to go to the user window, another one opens (like the type when you shut it down without pressing restart from the start button). It revealed that the file WINLOGON can't be opened, is damaged or someone had "accessed denied" it, and the laptop is having a FATAL SYSTEM ERROR. I couldn't get the rest because it was fast, and after that it reboots again. The process goes on and on.

I'm too freaked out to do anything at the moment. I'll content myself to consulting an expert computer technician and rely on him instead.

Right. So in the end, the solution was to have everything deleted. The final mark was (ultimately) to reformat the system to get rid of the virus, along with Drive C. Well, at least that takes care of the virus. *whine*

Anyway, I apologize (especially to the site admins and moderators) if this topic might appear like a blog instead of a real forum, and also to the ones who moved my topic to a more appropriate forum. I'm fairly new here as you can see and I think I've messed up a bit. :thumbsup: I appreciate everyone who read this topic and hopefully, have learned something from it. I sure had. :flowers: Nothing beats a hard-boiled experience.

Good day.
