What is wrong with my computer ?

ya.. computer is good unless you go for internet access. it will harm once go for internet access. so regular updated for anti virus is good for computer. it wont harm any way.

If all else fails, download the ccleaner from its corresponding website. CCLEANER. It is a registry cleaner and it will basically dump all the unwanted, unused and infected files from your computer. Run the cleaner and the registry cleaner for optimum performance. I find I need to run it at least once a month now since my pc is used by so many people right now... Usually it works for me and it will definitely clean up any viruses you may have in your PC. hope it helps...

Hello Friend... Lots of issues can slow down your computer, as you have mentioned that your computer used to run at very good speed I assume that your computer's hardware configuration is good. And assuming that you are using Windows OS,I can tell you some points which you can check out. 1. first check your C Drive where the programs by default are installed, check whether it has enough space remaining, if it has not you have to remove some data or software from it. 2. Check for .tmp files which are automatically created when you run a software or install any new software.In your computer to check and delete tmp files and temporary internet files go to start/programs/accesories/system tools/disk clean up. 3. there are many free registry scanning utilities free out there, I use free registry cleaner, which is very easy to use, run it after installing and find the registry errors and fix them. 4. Check for the fonts folder, if you have numerous number of fonts installed in your computer,they slows down computer. 5. Surely check for the Viruses by an updated antivirus. Have you done all of these already?

I have also come across to this kind of problem.When I first bought my computer,it's super quick,and my internet conection is very quick also,and I installed norten anti virus in my computer.But now,my computer is just as slow as a tortoise.
