Sometimes a person thinks they are downloading something that will be helpful to them, such as AntiSpyware 2008 XP. However, this program is not helpful.
AntiSpyware 2008 XP is a very aggressive self-advertising installation. It misleads the owner into thinking their computer has a lot of viruses and sends the owner to their own website so it can be downloaded. It is malware and will damage the PC irreversibly if kept on the computer.
To get rid of AntiSpyware 2008 XP, really good spyware removal tools are necessary. Do not believe that keeping the program is in your best interest. You need to remove it at once.
