What antivirus software are you currently using ? Well.. after a period you pc may slow down. 1. Defrag ur hdd. 2. Clean Temp files (CCleaner) 3. Tune-up (TuneUp utilities 2007) 4. Delete files that you not required. 5. Add RAM. 6. Don't open too much application at a time. 7. Don't install NORTON OR Mcfree.

chances are that your antivirus is working on the background scanning in real time every file you open and message you send/receive... this slows down the computer, because it's additional work

How many antivirus and firewall installed in your computer. If you have more than one, you should remove the others, because if you have more than one antivirus in your computer, will make your computer instability, Because there will be collision between one and another. Other thing that might happen in your computer is that an antivirus will always running on background, which will use much memory in your computer, so your computer will lose many memory which can slow down your computer.

All these applications run in the background and hence use resources of your PC. Some applications like Norton Anti-virus are resource hungry and recommend to have 512MB of RAM at least to run. In addition anti spywares, firewalls and also numerous windows processes all running the background eat up valuable resources in terms of CPU usage and RAM space. This can cause more swapping from hard disk when you run front end applications like MS Office or watch videos and play games. All put together in case the system is not having adequate RAM or a good CPU or a reasonable graphics card too much load on the CPU and swapping of data from the swap file which resides on the hard disc ( a hard disc is a very slow peripheral) causes slowing down of the system.

I recommend you not use the big commercial AV or Firewalls. Use the windows firewall and an anti virus that is light on resources like nod32.
