What is mivvx.dll?

[antonyliu2002]

I've never had this.

Look:

This one happened to me only two or three days after I re-installed
(clean install) my XP Pro system.

Right after I login to my account, before my desktop icons loom up, an
error popup window says, Can't access mivvx.dll, access denied. Or
something like that. I click the OK button on this popup and then
windows proceed to load my desktop just fine.

I browsed to C:\Windows\System32 and found this perpetrator as shown
in the PNG image above. My AVG says it is a thread, but was not able
to heal it.

Google turns out no hit. Is this something new? Please advise and
let me know how I can get rid of this bad guy.

Thanks.

Just becuase Google doesn't turn up anything mean much except the chances of it being
legititimate is low.


Please submit a sample of "mivvx.dll" to Virus Total --
http://www.virustotal.com/flash/index_en.html
The submission will then be tested against many different AV vendor's scanners.
That will give you an idea what it is and who recognizes it. In addition, unless told
otherwise, Virus Total will provide the sample to all participating vendors.

You can also submit a suspect, one at a time, via the following email URL...
mailto:[email protected]?subject=SCAN

When you get the report, please post back the exact results.

I've sent mivvx.dll to (e-mail address removed) as an attachment.
Submitting from virustotal web was not successful.

Not sure how long it's gonna take for me to get the result.

OK, I did not realize that. But then, there is no easy way to submit
it. Gmail does not allow sending executables, and submitting from
virustotal web also returns "size 0". Maybe I'll try using Yahoo!
Mail and see what happens.

Will get back to you later. Thanks.

No. The process that loaded it has to be killed first so the file handle is closed and THEN
it can be submitted.

It also is indicative that this was a righteous call and this a a dowloader Trojan and AVG
said it was.

Look at the following screen snapshot:

http://farm1.static.flickr.com/131/422806116_01861fcff1_o.jpg

This popup occurs right after I login password is accepted by windows
xp and before the desktop icons loom up. After I click the OK button
of this popup, windows proceed to load the desktop.

I forgot to say in my previous posts:

1. I am not sure what process is using this mivvx.dll.
2. I tried booting to safe mode and attempted to delete mivvx.dll.
It was not successful. Windows says that I cannot delete it because
some other program is using it.

In addition to the preferred method, submitting samples to VT and/or
Jotti, you can send samples to AV vendors by email. In most cases, you
want to put the sample in a password-protected archive (zip file) and
attach that to the email. Here is how to send a sample to Kaspersky Labs.

You can check with other vendors for similar procedures. In most cases,
you don't have to be a customer in order to submit a file.
