If your browser is
infected with Malware or just simply crashing, there are steps that you can
take to clean it up and give it a good chance of working. If it still does
not work, then you can repair or reinstall it.
Before you start down this path, make sure you
have run a Malware detector like Spybot,
scanned for viruses with something like Housecall
and have completed a log file from Hijackthis.
First, lets clear all the "Temporary Internet
Files" and any other temporary files.
Lets look at the Internet Explorer way, in Internet Explorer, Tools -
Internet Options - General - Delete Files (IE6) or simply Delete and select
There is a tool called ATF cleaner that works
well and deletes more that just the Internet Explorer items. You can get it
from my "Tools in review" page. If this does
not work or you suspect the temporary files are not clearing, try this
script (Run the batch file first and
then the script).
If you are technical and know a bit about
computers, you can drop to a command prompt and type in
subst x: "%userprofile%l\Local
Settings\Temporary Internet Files"
Where x is a free drive letter on your
system. Now open this drive letter up in my computer and delete any
remaining temporary data. Quite often Outlook and other tools dump other
files here temporarily (like email attachments) and they might not get
cleaned up. This is a great way to make space and also a great way to remove
any Malware (or at least fine it). If you find Malware this way and can not
delete it, you might need to used Process explorer (from
my tools page) to terminate the process and then delete it. If that does
not work, boot into safe mode to kill it. If that does not work, try using

This discussion is for IE6. The same things can be done in IE7 but the
buttons and sections are worded slightly different.
Please note that these instructions will not attempt to reset the colors,
fonts, languages, Accessibility and Temporary Internet Files location
options found in the General Tab and the dial-up connection settings found
