I am using Firefox as my browser. Yet, every time I try to log on to it, Internet Explorer comes up with this "about blank" page. I try to close it and it simply multiplies itself. I eventually have to manually turn off my computer.

How can I keep this from popping up and how can I get rid of it without manually turning off my computer?

Ok, so here is my problem. I was on myspace looking at a music artists’ photos, when all of a sudden, my anti virus program (Avast) pops up and tells me a whole bunch of viruses are invading my computer. After this occurrence, my internet has been really messed up.

So over the past 5 days or so, I have been virus scanning my entire computer about 10 times, and my anti virus cannot find any more viruses. I have also done anti-spyware scans and I have eliminated a bunch of spyware, too.

When I say my internet has been really messed up, I mean this: My anti virus’ script blocker and all of the other blockers are on their highest settings along with Firefox’s pop-up blocker, and I still get pop-ups, something I have almost never gotten before.

Besides this, when I try to visit websites, my Firefox error console gets riddled with error messages telling me it doesn’t recognize or can’t read a certain part of a website and it says "Declaration dropped."

Also, when I tried to install a registry clean up software, I got a message saying it wasn’t a valid Win32 application or something of that sort. I eventually got one installed, but my internet hasn’t shown any signs of improving.

By the way, when I typed in Firefox’s website to try to re-install it, the website wouldn’t load. It just wouldn’t. Also, Google Chrome and Internet Explorer aren’t any faster.

My computer can still play video games and do almost everything else that doesn’t include the internet just fine, but my internet is just so messed up.

Can someone please help me? My computer internet has never acted this way.

Thank you!!!!!!!!

Can anyone tell me ANY ways, free programs, guides, or tips to make windows vista home premium, internet explorer, firefox, windows mail, limewire, itunes, aim6,windows searches, or any other virus/spyware removal programs , or any other big memory usage or slow programs faster! Also, any ways to make any programs use less memory or ram, and improve overall ram usage and memory usage!

I have 2 gigs of ram, i disk defrag/ cleanup/ registry clean,virus and spyware scan all the time!

Also, any tips on lowering cpu usage???

I am using Windows XP and all of a sudden, when I clicked on the shortcut to MSN Messenger one day (after starting the computer), it didn’t respond. It seems to be "working somehow" (light indicator showing something is happening and the computer is buzzing) but the Messenger window never shows up. I have uninstalled it several times, rebooted, installed again, but to no avail. I have also removed the shortcuts and created new ones. Nothing seems to work. The process is running though – msnmsgr.exe. I don’t know why the computer started behaving this way. I have an antivirus, don’t go to any suspicious sites, etc. Also, quite recently, my Firefox stopped remembering and suggesting form entried used in the past although it is set to do so. Is it possible that my Windows XP need reinstalling or so? I have had the computer for 2 years. I have a RegistryCleaner that I use from time to time (and have used it now again with no improvement) that always finds lots of errors, etc. and fixes them. (Although I suspect it is quite possible that the registry cleaner may have caused some mess too.) If you have any suggestions, I would be grateful. Thanks a lot in advance.
Adding some details:

Thanks, I have done so and all went fine. Except for the fact that it has not solved my problem, unfortunately. I have tried installing it, uninstalling it, cleaning the registry, etc. and all in vain. I have really no idea why it is doing what it is doing. All of a sudden. Any other idea? Thanks a lot in advance.
