I had XP Home Security 2011 on my laptop which is running XP Professional with Service Pack 3. I got Malwreabytes to run and it quarantined/removed several infections. Now for example, when I click on Internet Explorer in the tray (and some other applications including Malwarebytes) it does not open. An "Open With" dialoge box opens. It says Choose the program you want to usee to open this file: iexplore.exe. Internet Explorer opens normally from the icon on the desktop. Also. when I Click "Atast" then Control Panel" and then "Add or Remove Programs" I get an error box that says C:\WINDOWS\system32\rundll32.exe Applicatioon not found. I have tried replacing the rundll32.exe file from several sources including the Wiindows replacement disk that came with my laptop and nothing changes. When I go into the other user in a different domain on the laptop, everything seems to run normally. What can I do?
