If you have not yet heard of Animiz then there is something wrong with your work. Animiz is a free antivirus program that you can use on your computer. It is a very good antivirus program, but it does cost money to keep it up and running. So, if you don't want to pay Animiz you can download it for free. This will only get you a trial version, but you can try it out before you decide if you want to pay for it.
When you download an application like Animiz you should be able to use it without any problems. But even after you download the free version you should still get a message from Windows telling you that Animiz is missing. This is because the main program will not be installed properly. To fix this you should be able to use the built in Windows repair tool. It is called regedit.exe and you will have to run it by opening Start, typing "regedit" and pressing Enter. This will open the windows registry editor. Once you have run regedit, you should be able to see the Animiz file.
To fix this you will need to manually edit the file that is in the registry and force Windows to install it. This will cause some damage to your system so you should take care. Once you do this then your problem should be fixed. If Animiz still does not work after you have deleted it then it is time to look for a new antivirus program.
