File association fixes for Windows Vista.
I'm running Windows Vista on my desktop, and every time I try to open a file, program, or anything else for that matter, I get an error that reads "This file does not have a program associated with it for performing this action. Create an association in the Set associations control panel." I can't even Firefox. The only way around this program that I have found so far is to right click it and select "run as administrator", but I get a warning popup every time, and it gets really tedious. I just want to be able to click something and it opens..
This problem started today after my computer got infected with a fake anti virus program called "vista internet security 2010". I looked for ways to remove it and several sites recommended removing:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center "FirewallOverride" = "1?
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center "AntiVirusOverride" = "1?
HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet\IEXPLORE.EXE\shell\open\command "(Default)" = "av.exe" /START "iexplore.exe"
HKEY_CURRENT_USER\Software\Classes\secfile\shell\open\command "(Default)" = "av.exe" /START "%1? %*
HKEY_CURRENT_USER\Software\Classes\.exe\shell\open\command "(Default)" = "av.exe" /START "%1? %*
Using regedit, I was able to remove some of those, namely the last three.
Ever since then, I couldn't open anything without right clicking and selecting run as administrator.
Can anyone help?
