Hi, last week my Windows XP home-edition laptop was infected with the Windows Defender 2010 virus. I followed the directions from this article (http://voices.washingtonpost.com/securityfix/2009/09/what_to_do_when_rogue_anti-vir.html
) to remove it, including downloading and running Malwarebytes and Superantispyware, as well as Norton Anti-virus. I ran them in this order: Norton, Superantispyware, and Malwarebytes. All three picked up threats, which I deleted or quarantined, depending on what it'd let me do.
After running Malwarebytes, the annoying Windows Defender 2010 stopped popping up, BUT now every time I open a program (be it Firefox, Norton, etc.), I get the "What program would you like to use to open this file?" window.
I then tried to do a system restore to an earlier date. However, when I tried to run system restore in Safe Mode and in Normal Mode, I got the message that "System restore has been turned off by group policy..." To try to fix that, I tried both the regedit.exe and gpedit.msc fixes suggested here: http://windowsxp.mvps.org/srpolicy.htm
Now when I try to run System Restore from Safe Mode, it says I must run it in Normal Mode. When I try to run it in Normal mode, I get a message that says, approximately, "System Restore is disabled. Do you want to enable it?" And when you click "Yes," nothing else happens.
What do you suggest I can do to make my computer run normally again?
Thank you for your help!!
