All you have to do is download, scan and then it automatically removes the spyware for you!

It’s free to download and you only pay if you like the software and want to keep it. I also found it to be really easy to use and very effective in removing all malicious viruses, spyware and adware.

Run a full system scan with this tool:

It’s a top-of-the-block tool that very few people know about — but it’s very effective. I’ve never had a problem with adware, spyware or any of the tricky trojans since I got this installed and running.

The selected item(s) may be in use, e.g., open. Windows does not allow delete and Anti-spy is caught in the middle. More sophisticated anti-spyware programs will kill the process that is using the files or schedule them for deletion upon reboot. You might be able to get around the problem by booting up in safe mode and then running Anti-spy. Alternatively, you could try installing the free version of SuperAntiSpyware (my favorite Anti-spyware program) at superantispyware.com, update the definitions and run a full scan. It’s up to you.
