I couldn't find any information about removal of Astry.A. Panda has a pretty good workup on this infection at https://www.pandasecurity.com/homeusers/security-info/about-malware/encyclopedia/overview.aspx?lst=det&idvirus=178398 on the Web.

Here are some suggestions--try them in the order listed:

Download and run a scan with the free version of Malwarebyres' Antimalware scanner at https://www.malwarebytes.org/index.php on the Web.

Try the Panda free Panda Active scan--see the ClamWin antimalware page for location.

If that doesn't work, try a scan with Dr. Web's Cureit infection remover--see the ClamWin antimalware page for location.

If that doesn't work, try a scan with Norman's Malware Cleaner--see the ClamWin antimalware page for location.

One of these should work. If they don't, the antimalware page might give you some places to get help. If nothing helps, you will have to reformat/reinstall. Good luck!
