Downloaded IE 8 Computer Now Very Slow

Specs: Windows XP
Several months ago, I downloaded IE8 in Windows XP (with SP3), and it worked fine for a while. After about a month, I got a message about a change being made from my antispyware -- did not allow it. After that, had a lot of trouble connecting to the internet, so I removed IE8 and went back to IE7. Now I can connect, but the computer runs very slow. Security scans show several HCKU files with questionable site names (none that I have visited, most X-rated). Any thoughts on how to remove them, and get the computer to run faster?

What security programs show these dubious website reg entries? Most scanners have the capability to allow you to remove whatever they find.

If you are using "SpywareBlaster" and/or "SpyBot Search & Destroy Immunize feature" then you will have all sorts of dodgy looking websites appearing in the HKCU part of the registry (ZoneMap > Domains), which are sites they have blocked. The blocked ones have a kill bit of 4. I assume these are not what your scanners are reporting.


What's the time?

At the time, I was running SpyBot. It kept opening multiple windows with a change message. So many that it was impossible to get any work done. I have since removed it, and rely on McAfee (which I have been using since I purchased the computer 2 years ago). I noticed the sites when running the weekly McAfee scan (which has found and destroyed some items). Recent scans have not found any problems, I can see those site references scroll by as the scan is proceeding -- someone told me that they could be why the computer is slow.

In the early versions of IE8 there was a definite issue about too many entries in Restricted Sites (those registry entries I mentioned) causing IE slow downs. They can be removed but IE8 has now been changed and IE7 was never affected.

The only way to find out which entries SpyBot put in is to re-install SpyBot, Immunize, then run their Immunize Undo. This might leave behind a very small number that MS (or other) have put in. You could then uninstall SpyBot if you wish, although those change messages were due to their "T-Timer" utility which is a real pain and definitely best disabled.

Having said that, leaving those sites blocked shouldn't be any real hassle (even beneficial) but you might spot them when scanning. If there is anything real lurking McAfee should pick it up.

I don't know the answer to the slowness because there are all manner of things that can cause this. Clearing temporary internet files and limiting unnecessary background programs would be a good place to start. Some sort of "nasty" is always possible but I think what you are describing is just blocked websites (see IE Restricted Sites).

one more thing....

Against the possibility of some nasty cauising your slow-down, Download, Update and Run MalwareBytes free version. This often finds and fixes things that AV's miss.

Re #5

If you have a problem that has suddenly happened then it is best to fix that before considering other browsers. Lots of folk are running IE without any hassle. I use both IE and Firefox and can see little speed difference.

If you eliminate an infection as a probability, then....
Consider memory. First, do you have enough (modern browsers need more than before, add to that your AV protection also) and second, test memory for a bad memory stick. Use Memtest to evaluate.

Thanks, all, for your feedback! After trying various solutions I ended up rebuilding my computer, and am now running IE8 with no problems. I've also added back the anti-spyware/adware to my security -- hopefully my computer will now stay virus-free... :-)
