I'm running Windows 7 64 bit. Yesterday I asked this question. No need to read it. Right now, my anti virus, detects no virus however I am experiencing 2 issues:

  1. When i start windows, the screen goes black for like 15 seconds, before i see the login screen, I didn't have that issue before.

  2. I said in the previous question

All of those removed some malware (I don't like to say virus), but every time i start windows, 2 or 3 minutes later, i see a command prompt, that opens up and closes faster than you can blink, i strongly believe it's a spyware, but i can't prove it.

So today I decided to find out what's that command prompt, i downloaded camtasia studio, recorded the screen and waited for the command prompts to pop up, then i slowed the frames of the video using camtasia and vlc and took these snapshots

Is it a malware or a driver issue or something?

Seems your printer drivers were not correctly installed. the System.IO.FileNotFoundException is a Java Exception, that signals that the program didn't find the files it was looking for. – Doktoro Reichard Sep 21 '13 at 16:37
+1, I don't think it's malware, but I'll do further research – matan129 Sep 21 '13 at 16:38
Great catch on the CMDs for us. I've had the black screen issue before as well, for me it was old graphics drivers. The above suggests HP drivers - do you have an HP? Did you install those recently, at least since the new weird things are going on? I'll do some extra research as well - but it doesn't sound too alarming at this point. – nerdwaller Sep 21 '13 at 16:40
@Fischer, just saying, I always keep my installation files on my extremal HDD so i can install everything quickly. However, try to update the HP drivers and see if the problem is gone. About the black screen at startup, try to disable startup programs & services with msconfig. Many stuff that's activated with the PC may cause it to be extra slow before login – matan129 Sep 21 '13 at 16:48
@DoktoroReichard - System.IO.FileNotFoundException is a .NET Framework exception. This has nothing to do with Java. HP is a big fan of .NET in their programs and likely is using it for their service – Ramhound Sep 23 '13 at 11:07

When you consider all the issues you've been facing lately, it's clearly time for a format and new installation of Windows. I saw in your last question that you're trying to avoid that, but the amount of time you've already spent wondering if foo is a virus and if bar is working correctly, you will probably save time at this point by starting with a clean slate.

I saw previously that you don't have a Windows installation disk. Take a look at this question.

As for your current 'is this a virus?' question, it doesn't seem to be, but it wouldn't surprise me if it were related to a previous virus. In my experience, removing viruses or malware typically leaves behind broken pieces of Windows.

I've brought this up before on meta, and while some don't agree with me, I believe the only way to fix a computer with a virus is to nuke the entire hard drive and start over. Anything less than that, and you'll always be wondering if the machine really is fixed.

I see your point of view, and i vote it up, even if i don't agree with the answer, the last part, I don't know if I'm ready/willing to nuke it, but i do know that if i ever nuke it, i'm not going back to windows – Lynob Sep 25 '13 at 8:38
