Legit or Malware?

Yesterday I was browsing & got the window. I cancelled it.
Today too I was browsing & got the window. I cancelled it.
I was browsing trusted sites & no shady sites.

Is this legit or malware?
Attached is the screenshot.

Win 7 64 Bits

 

I also got this yesterday - and like you, I was not in "shady sites". I also had WinPatrol reject it and shortly later regretted it. My disk had errors and I couldn't fix them. Eventually, late last night, I had to restore from Macrium Backup in order to get back to where I was earlier in the day. I guess I screwed up something by rejecting the Windows Installer pop-up. I don't have a clue what it was or what it did to my pc.

 

I got & rejected it 2 times. No probs with the system yet.

 

If I double-click and manually run Msiexec.exe I get the same window. It looks like something is calling Msiexec.exe. It might be some installer calling that exe without parameters? Try to find out which process has run msiexec.exe to find out what's causing it. You can use Process Explorer to find parent process.

I never got this window.
Couple of days I am running Bitdefender Free AV, could BD be the reason?

 

Which window, the one from your first post?
You can try and remove Bitdefender and you'll see if that was a problem.

Yes that window.
I am not getting it often, as I mentioned in my previous post, got twice.
When I rejected it, tried 2-3 restarts but it didn't appeared.
Today too I rejected it & tried 2-3 restarts & it didn't appeared.
So I guess uninstalling BD would be waste & BD is not the culprit here.

 

To find culprit try suggestion in my first post. Something is executing msiexec.exe. Try to find out which process is running it and that might give you information where to look. Of course you will have to wait until it happens again.

Another long shot question: do you use Chrome 32 and CCleaner with version lower than 4.09?

You mean when the window appears again, msiexec.exe will be there in the processes & I should check its properties to see whats calling it?

 

Yes, but properties won't show you what's calling it. Use Process Explorer which will show you parent-child relationship for each process.

OK.
Should I run chkdsk & sfc /scannow & check?

 

I would first try to find out what's causing it. You might also want to check your Event viewer and see if there are any new records that might be connected to this problem.

EventViewer shows MsiInstaller which shows googletalkplugin update, guess this is the culprit?
I guess when the window appears again, it would be safe to accept it, right?

 

Might be that, yes. Accept it and you'll see if installation will continue.

It had appeared again & I had accepted it but nothing visible happened.
Today it appeared again & I again accepted it & nothing visible happened.

sfc /scannow didn't find any errors.
chkdsk didn't find any errors.

I think Google Update is the culprit for this window appearing coz when this window appears that times log in eventviewer is google update that mentions update failed, either its not installed or corrupted.

I have Google Chrome, Picasa & Google Talk on my system Win 7 64.

Under services, there are 3 services related to Google.

Google Update Service (gupdate), Automatic (Delayed Start), Stopped
Google Update Service (gupdatem), Manual, Stopped
Google Update Service, Manual, Stopped

Any of the above services Status & Startup Type is wrong & needs to be changed?

 

Removed all the google softwares, chrome, picasa, autobackup & google talk & remnants.
Reinstalled chrome & picasa.
Lets see if the window appears now or not.

Google talk is discontinued?
