having browser problems

I can browse the web but periodically the browser acts like it has no connection.
This is happening in both IE8 and FireFox 3.5.3.
IE will say there is a problem with the connection and FireFox will simply just not load web pages or give me an (Untitled) tab, although I can sometimes get my homepage (google) to come up no problem and even search with it but I can't load any pages in the search and sometimes I have to click the GoTo button on FireFox to get pages to load.
I have tried creating a new profile with it, running it in safe-mode (no addons), reinstalling Java/Flash player, and even uninstalling/reinstalling the browser with no luck.
It also sometimes doesn't load images on webpages.
The connection is still there because I've tried playing a few online games and tabbing between them and the browser and it was only the thing acting up.
I've ran malwarebites/SUPERanti-spyware/AVG9 Anti-virus and nothing has came up on them.
Someone please help it is getting really annoying.

I am on Windows XP Pro with service pack 3
AMD Sempron Processor 3000+ 1.81 GHz
1.25 GB RAM

 

I just tried to load a few pages in IE8 and on the first few tries it attempted to download and save them as .html files.
On the second try it gave me this:
Error Signature ----------------------------------------------------------
AppName: iexplore.exe AppVer: 8.0.6001.18702 ModName: ieframe.dll
ModVer: 8.0.6001.18828 Offset: 00033b9f

 

Sounds to me as though you having a few mlaware/ spyware problems and your browser is becoming part of it now have you tried restarting in safe mode, making sure all your AV's and mbam and sas are up to date first and then try running them in safe mode, see if that helps ! Failing that i suggest you move on to the malware section and get started with READ and RUN me First !

 

I have ran CCleaner and wiped everything out of temp files.
It's not my connection because there are other computers on my router and browsing on them is fine, no problems whatsoever.
I am on a cable connection too by the way.
I tried to load up safe mode with networking but it wouldn't bring up any pages while browsing even after i clicked off offline mode.
I am using the built in windows firewall.

I've re-ran all the anti virus/malware/spyware removal programs in safe-mode and I will be posting them in the malware forum to see if that might be the problem.
But any additional information anyone has regarding a non-malware issue of this type would be of great help

 

sorry about the delay in replying but my browser just let me load the site
but i have ran what you said with no problems (i posted my logs in the malware forum under "need some help to verify if anything is on my machine") if anyone can figure out if its malware then please post in the malware forum under my post it would really be appreciated
but if anyone has any non-malware tips then please reply me and i will try them just to see if i can fix it because it has become very annoying

 

I don't think any non malware tips are going to help you, as i stated in my last post you definitely nead to do READ & RUN ME FIRST. Malware Removal Guide and post it in the malware section of the forums, but i must point out that the malware fighters are hard at it all the time, so you must be patiant and they will get to you, but also in the meantime just go through the above link i've given and follow the instructions very thoroughly and carefully, as the procedure has to be done in ceratain ways depending on your OS !

 

I unplugged the router for 1 minute and plugged it back in.
The connection had to find the address for a minute but when it found it it was working fine for a minute, then it started doing the same thing again.
The other computers on the router are still browsing fine it seems to be just mine acting up =/

 

As i said this seems to be a malware/spyware problem ! READ & RUN ME FIRST. Malware Removal Guide

 

I have posted all my logs in the malware forum and I am awaiting confirmation from someone there.
But I seem to have fixed it (for the time being) by uninstalling AVG Anti-Virus 9.0.
I've been loading and refreshing random pages for about 20 minutes now with no problems loading them (even all pictures/flash/java apps load).

 

Maybe just by running the programs as i said, may have sorted out your problems, lets hope so and your all clear and up and running again, good luck !
