Computer help forum: Why IE very slow, but FF fast on a x64 3GB PC?

Roll back to the earlier version. Delete IE9 reboot and the system should roll back to the earlier version. Similar issues have happened to others with the upgrade, it is an MS thing and if you ask them (MS) you will get more of a headache than you had fighting with the glitch.Then, at some point in time (when you feel brave enough) try doing the upgrade again, of course there is always good old MOZILLA, which just seems to roll on. Best of luck!!!

Have you tried scanning with a different tool such as the free Malwarebytes and SuperAntispyware below? If not, give them both a try. Download, install, update, then run full system scans to make sure there's no malware on the machine.

One other thing comes to mind regarding IE and the slowdown.. A lot of folks think registry cleaners and "system optimizers" will speed things up.. Instead, here we find they tend to do the opposite.. If the eMachine has had such registry cleaners run on it, you may be seeing the aftermath of the wrong registry entry being removed.. If the cleaner has a "undo" option, give it a try..

Hope this helps.

Most issues with IE come from add-ons.

Things to try:
1. Try IE in a new (just temporary) Windows account. Might very well be fast.
2. If that's a success, run IE in the original account and use Tools>Manage Add-ons to disable all. If it's OK then, enable the ones you really need one by one to find the culprit.

I have also had this problem I ended up with a reinstall Win7pro 64bit then tried IE9 again [which I liked] and it slowed right down again after a Win update so UN-installed IE9 and ran IE8 which was OK.
I am fully aware that add ins can cause problems with browsers but I had NO add ins installed on IE9. I checked all over for solutions [a lot of people with the same problem] could find no valid solutions to the problem [lots of crap about remove all add ins to solve but this is a red herring But unfortunately it is the only senile solution being touted it is has no relevance to this problem] I am convinced that it is a defect that is introduced through an update and no one has owned up to the self destruct of IE9, so I to have installed Firefox8 to use and as much as I am an I.E. fan I must say that this is a very adequate browser apart from the memory leakage its a decent browser. Such a shame that nobody at MS can sort out I.E..9 I think that they are in denial?
