General discussion


A couple of weeks ago when I started my machine Spybot poped up a message saying that "mscorsvw.exe has been changed", and then something about wmiprv that I do remember the details about. It was after a windows update so I assumed that it's normal.

Last night I came across a site on the internet about wmiprv being a spyware, so I scanned my machine with Malwarebytes' anti-malware (full scan), hijack-this (regular mode and safe mode), AVG free, Spybot (Safe mode), but couldn't find any spyware or wmiprv. Is there anything else I can try? I don't think wmiprv will go away itself so I am afraid that it's hiding somewhere.

Many thanks.

Why don't you run an on-line scan......

Please perform this online scan: F-Secure Online Scanner
The online scanner is on the bottom right of the page.
Follow the directions in the F-Secure page for proper Installation.

* You may receive an alert on the address bar at this point to install the ActiveX control.
* Click on that alert and then click "Install ActiveX component".
* Read the license agreement and click "Accept".
* Click "Full System Scan" to download the scanning components and begin scan and cleaning.
* When the scan completes, click the "I want to decide item by item" button.
* For each item found, Select "Disinfect" and click "Next".


Please run the Housecall online virus scan located at:
Follow the prompts to scan your hard drive for viruses. Select the "Autoclean" option so that Housecall will remove any viruses from your system.
When the scan is finished, please restart your computer.

Do the scans find anything?

Couldn't scan

Thanks a lot Marianna.

After I started a scan at (once I finished the system checking step), a message poped up saying that there's error in transferring the data, do you want trendmicro to resend it. I clicked Ok, the same message poped up. I retried a few times and clicked cancel to stop.

I followed the directions to do the F-Secure scan, it downloaded some files and installed some exe, then it says "preparing to scan..." on the scan pop up screen, and I waited for 20 minutes and nothing changed (ie/ still preparing to scan). I closed the window, started another scan from, then "an error has occurred, please close the browser and the scanner and try again (Id: 15)". I repeated a few times but kept getting the same message. So I tried starting from firefox, but f-secure doesn't support it.

I don't know if it has to do with my OS. I am using Vista Home (sorry I should've mentioned it in my initial post).

Is there anyway to uninstall/remove the f-secure exe and database files that I had installed? I haven't been able to find them via control panel nor in the c:/program files directory.

Is there anything else I can do to look for the possible malware (wmiprv) on my system? Thanks again for your help!

How could users completely remove HouseCall 6.5?

1. Close all open browsers.

2. Depending on the operating system used, delete the folder that contains the HouseCall installation files from the home directory:

o Windows XP/2000/2003/MCE2005:C:\Documents and Settings\UserName\.housecall

Note: Deleting these folders also removes all the quarantined files and backup files from previous scans or cleans, as well as log files.

If deleting the ActiveX Object, refer to How could users remove the HouseCall 6.5 Internet Explorer ActiveX Plug-in.

Thanks so much

Thanks a lot, Marianna.

I've scanned with Malware bytes, but I will try Superantivirus as well when I get home tonight.

Actually I found the following keys in my registry (which seem to be valid... I hope), so I am starting to wonder if what I saw was wmiprvsd or wmiprvse instead of the malicious wmiprv... Thanks again for your help. Really appreciate it.

wmiprvsd.dll is a WMI from Microsoft Corporation belonging to Microsoft

Thank you

Marianna, thanks again for the info. Superantivirus doesn't find anything, so let's hope that it was indeed wmiprvse/wmiprvsd that I was seeing. Sorry about that.
