The more programs that you have running on your system, the harder it is for the RAM to perform. Inevitably, your system's RAM will reach the point at which it can no longer function, therefore it will either crash, terminate one of the programs, or start using hard drive space for additional memory. This will slow your machine down dramatically. Avoiding Viruses Viruses are small programs that attach themselves to data on your computer. They can attach themselves to documents, spreadsheets, or program files, or they can hide on your hard drive.
Viruses hide in another file and are activated when a specific event occurs.
The event could be a date or program or document being opened and they can attack at any time. All viruses affect your system differently. Some will display a message, while others will corrupt your files or erase the data on your hard drive. Your system can obtain viruses from a diskette, from a file that you save on your hard drive, or from an e-mail message. Try running the Scan Disk and Disk Defragmenter to make it more responsive.
