1) Anti Virus
A virus is an intrusive program that infects computer files by inserting in those files copies of itself. To prevent this, it is vital to have a good proper Anti Virus program on your PC. There are many free downloadable Anti Virus programs (non-commercial usage) available on the Internet.
Avira and AVG are our recommendation for home users. Once you had download and installed on your PC. Make sure to update your Anti Virus definitions files regularly and schedule to run the Anti Virus program at certain time when the PC is on.

2) Disk Cleanup
When a hard disk has more data, it will takes a longer time to perform a task, therefore it is important to get rid of unwanted clutter. Disk cleanup has options to safely delete any unwanted files, but make sure you do not need them before you proceed to delete them. To start Disk cleanup, go to Start -> Programs -> Accessories -> System Tools -> Disk cleanup. Do run Disk cleanup on a regular basis.
