Fix Slow Starting of Internet Explorer
After dealing with a number of machines with serious performance issues with Internet Explorer, we have come up with a solution. Clear out the Restricted Zone. This is especially necessary with Internet Explorer 8.
It helps to use a utility that can clear out the Restricted Zone in mass. We have used ZonedOut by http://www.funkytoad.com/ . It is a simple tool that makes it much easier to manage a large Restricted Zone, or delete all entries at once. It also provides you with an easy way to back up your zone entries before deleting them, so they can be edited and reimporting. Or if you just want to clear the zone for testing.
Normally I wouldn’t recommend doing this, because the restricted zone can be a good tool for keeping out the bad guys. But clearing it out improved the performance of Internet Explorer ( and also any browser that uses the IE engine, such as Maxthon). On one of our machines, IE was taking about 25-30 seconds to open. After clearing out the Restricted Zone, it opens in about 5 seconds.
Then use the built in tools in IE8, or use a safe surfing security tool such as provided in many security suites and anti-virus software and firewalls. Just try not to use more than one, or they start tripping over one another. Same with having multiple tool bars, like Google and Yahoo. Don’t use more than one.
UPDATE:
If you use any security software that adds to the Restricted Sites list in Internet Explorer, you may want to modify its settings to prevent this. We have found that Spybot Search and Destroy will add about 10 to 15 thousand sites to that list, and Spyware Blaster will add tons more. In Spybot, go to the Immunizations tab and uncheck the domains for all users on your computer. In Spyware Blaster, you can disable this by by disabling protections for Res triced Sites. Is that a good idea? Depends on what your other security software does for you. But, if you don’t, these programs will add thousands of sites back to the list ASAP, and IE will again be slowed to a crawl.
UPDATE 2: It appears that this slow starting issue is resolved or at least significantly reduced in the latest versions of Spybot and Spyware Blaster. In fact, it Spyware Blaster seems to have contributed little to this problem, and we recommend users return to full protection with both of these important security programs.
