what is wrong with my computer!?

my computer was working 100% fine like always

but yesterday morning i turned it on and all of a sudden the internet was being ridiculously slow. its att dsl and its never like that. it was being worst that dial up

and it was ONLY when i would try to search the web. when i connected the internet to my ps3 it worked fine.

so then (since it's been a while since ive gotten an antivirus) i went out and bought one (norton antivirus), scanned my pc and removed what if seemed to be 2 viruses. trojan horses (2)

i scanned the whole computer, removed the threats and restarted it. and now my computer is slower than ever! this time it isnt only the internet, it's everything. i deleted over 1gb of files i dont need, i have 49gbs still free

does anyone know what it can be or what i should do??

NOTE: my computer had an internal failure earlier yesterday when the screen went black and saw pixel-like squares everywhere. so i restarted it and that was when it was slow

    You going to need to download free AVG anti-virus to keep your computer safe from viruses: http://free.avg.com/us-en/homepage

    And CCleaner is a freeware system optimization, privacy and cleaning tool. It removes unused files from your system - allowing Windows to run faster and freeing up valuable hard disk space. http://www.ccleaner.com/

    I'd personally never buy an anti-virus as there is much out there that is free and does the job just as good, or better. While Norton could have eliminated some trojans, they aren't exactly easy to remove. Typically this involves eliminating them during boot phase since if it is running, it cannot be removed. I would probably try restoring to a time before this happened or reformatting and reinstalling the operating system.

    As for the second issue there that sounds like something freaked out in your video drivers. Try updating them.

    I used to consider it was once the wi-fi modem I had. Because, there might be instances while I would not be ready to do any factor on-line, and the shortcut on my computing device might say I have an Excellent Connection. Actually, what it intended was once, I have a pleasant connection to my wi-fi modem and the bars, within the Wireless Network Connection field, might be all complete and inexperienced! The wi-fi track software might say "You are connect with the modem, however now not related to Internet" or some thing like that. It's occurred to me so routinely, I do not consider you'll be able to hinder it. It constantly comes again. There's a well hazard, it is not your computer systems. Go Figure!

    Open task manager and see if a process is hogging the CPU. If you see a .exe that is search for that program on the internet to see which program the .exe belongs to. Then uninstall that program.

    Also scan your PC with Adaware. http://www.lavasoftusa.com./

    it is a free download.
