This is what it is and how it got there. Refer to the link below. This is why you have to be very careful of what you download and where you download it from, especially if the software is free. Video Download Converter Toolbar got on your computer after you have installed a freeware software (video recording/streaming, download-managers or PDF creators) that had bundled into their installation this browser hijacker. This browser hijacker is also bundled within the custom installer on many download sites (examples: CNET, Brothersoft or Softonic), so if you have downloaded a software from these websites, chances are that VideoDownloadConverter was installed during the software setup process. Here is a link that might be useful: Remove Video Converter Toolbar

A 6 mb line should be more than adequate for streaming video. Netflix says you need 5 mb for their HD signal, and 5 is close to the effective capability of a 6 mb line. So long as there aren't other users sharing the bandwidth of your connection, your problem shouldn't be the line. Have you tried running a speed test (speakeasy.net is a well regarded one) to see if you're getting the speed you expect? Is this a wifi connection, maybe with a lot of other dwelling units close by (ie, an like an apartment or condo) producing interference on your channel? You Tube is owned by Google. Downloads could be annoying but certainly not dangerous. On the other hand, I'm not sure what use you would have for what you're describing.

Working with video, even just converting it from one format to another is extremely taxing on the computer requires a fairly large amount of memory. With 256 MB of ram, my first thought is that your computer is paging constantly to the hard drive. If your hard drive is almost full or extremely fragmented, your system will lock up and crash. Let me explain. If I told you I was going to give you a ten digit phone number (area code + number) and asked you to remember it for a few minutes, you'd probably be able to do this from memory. Now If I told you that I was going to give you 5 ten digit phone numbers and asked you to do the same, what would you do? You'd most likely need to write it down on paper to be able to give it back to me. Right? This is the same thing that happens with the computer. The computer uses the ram in the same way you'd be able to memorize the first number. When it runs out of ram to do this, it needs to jot the information down, temporarily. It does this on a hard drive with what is called a paging file. Under default settings, the paging file size is managed by the operating system. If your computers hard drive is full to the point that the paging file is not what the operating system requires it will most likely crash. This can also happen with a heavily fragmented hard drive. Anyway, I went on a tangent there. I would recommend that you increase your system ram. The more the better, especially if your going to work with video. To get info on hard drive. Click my computer, then right click on your "C" drive and select properties. It will show you a graphical representation of the hard drive with free and used space. From this box you can select the "tools" tab and then the "defragment" utility to defrag the hard drive. Note that with 256 MB of ram, it will take an extremely long time if the hard drive is heavily fragmented and there is even the possibility it will crash. Do this overnight. The information on the video card can be found in the device manager located in the system properties which can be accessed int eh control panel. Control panel - system - hardware - device manager. Select display drivers - then your video card should show.
