Thread: System instability

My PC has a 2.8 GHz dual-core processor, 2 GB DDR2 RAM, NVIDIA 9400 graphics card. It hangs on regular intervals of a few seconds. I use a home licensed Avast antivirus. It says that there is a virus. I regular update it . Also, when I start my PC, it automatically opens the My Documents folder. A Window script menu is also displayed. Hope you can help me fix these problems.

The scripting errors that you see when your PC boots up is because of a worm or virus. If your PC locks up every now and then, that too could be because of the worm. One of the ways to fix it is to try a different antivirus or security sulte.
