Okay here’s the problem.

I got a brand new 300 Gb hard drive barely three months ago. Installed everything that’s needed. Media, open office, movie maker, internet, printer, anti spyware etc.

I’m using internet explorer and I’ve noticed over the past couple of days It appears to be slowing down. Before and after rebooting my PC it’s still slower than it needs to be.

Now I have some relatively powerful anti threat software on my PC.

I use Malware bytes, Avira, Ccleaner and Comodo registry cleaner. I also use Start page.com as my homepage. (start page claims to be more private/more secure for web browsing) After running all these.

First Malware bytes system scan, Then Avira system scan, Then the Ccleaner and finally Comodo system cleaner. I shut down the machine, restarted it and opened IE only onto start page. I don’t use google search anymore(too much spam)

Now after all this I still notice only after about 30 minutes Internet Explorer still slows down incredibly. (btw all the scan cleaned up everything with not apparent damage) But the web browsing is still noticeably slow.

Is there something on my pC that isn’t being caught or is Internet Explorer having some problem of it’s own? And if so how do I fix it?

PC is about 5 years old. Emachines computer. CRT monitor. HDD only about 3 months old, has 300 gigabytes of space and only 10 gigabytes of space has been used so far.
Any other specs you might need to diagnose this. Please let me know.

Thanx.
Oh and btw. Two things.

1. I’ve already cleared my cache and internet history MULTIPLE TIMES. And I’m still experiencing huge slowdowns. :-(

2. I used firefox on an old hard drive that was nearly five years old.(still have it) and for some odd reason firefox COMPLETELY CRASHED and I had to uninstall it from the hard drive permanently. I’m afraid of something similar happening to this new hard drive. So I don’t know if that’s an option.
