I am running Windows XP SP2. I use Firefox 3.5.5 exclusively. It has lately been making the CPU and Memory using spike and flux. This slows my pc and also makes my cpu fan run CRAZY. I see I have multiple instances of svchost.exe and I am thinking that isn't right or good either. Also KIS's exe process, avp.exe, seems to run high also at times. I am not sure if any of these other problems have to do with the main problem but I figured I should mention all errors.

I scan my pc with MBAM and KIS often. No malware, spyware, or viruses found. I use Optimum online, a cable internet service. I have a old HP model desktop with a AMD 2600+ pros, 2 gbs of ram, and a western digi 100 GB HDD.

Thanks for any help you maybe able to give me, Metman.

I found some information about changing a few things in the config section of firefox. PUt about:config in your browser and search on cache. This should pull up all entries with the word cache. Look for browser.cache.disk.capacity and change to 16384. Look for browser.cache.memory.enable and change this to false. I would also get the add-on Flashblock as most of my issues came from flash pages. If this doesn't resolve it dramatically there is also another setting that forces FF to release memory on minimize that I can dig up for you.

Hope this helps.

Free up memory on minimize tweak: http://www.solo-technology.com/blog/2005/1...tweak-free-mem/
Bare in mind it is almost 4 years old so it may not even work with current versions of FF

First, I highly recommend that you first upgrade to Windows XP SP3 for security reasons. Second, I would switch to Internet Explorer 8 as it is more secure than Firefox.

IE is a fail in my opinion, Firefox and Opera are both better browsers than IE. Some of the add ons for firefox (i.e NoScript and Adblock Plus) add a lot of security to it over IE. [End opinion]

They may add some security, but IE's SmartScreen Filter blocked out 80% of sites tested. Firefox only blocked 30%. You call that less secure?

Source?
And if you practice safe browsing, have a working AV and firewall, Firefox and Opera are both more customizable than IE and should all in all be a better choice.

Hmm, good read. Slightly outdated but the results are probably still around the same. I've never liked IE though, so my opinions are biased I must admit. I will continue to use FF, and as long as you are a smart browser, and get some secure add ons, you should be fine. IE or FF, both are quite secure, but it seems as if I was wrong and IE > FF in the security department.

Your very welcome. May I also suggest to you to run Windows Update as Windows XP SP2 is outdated and vulnerable to security attacks. Make sure that you apply all patches that Windows Updates suggests, and keep visiting there until there are 0 recommended updates.
