0 How to protect your PC from malware ?

In general, protection is provided after a new virus has been spawned. The following are some suggestions to make your computing safer.
•Don't open an attached file if you do not know what it is, who sent it to you, or you were not expecting it (even if it is from somebody that you know.) This is especially true if the file has any of the following extensions: .pif, .vbs, .scr, .exe
•Don't use the preview pane in Outlook. Some viruses can infect a computer just from the preview pane.
•When in doubt, contact the sender. Write back to them and ask what the attachment is. If the attachment is valid, they will tell you what it is and what it does.
•To permanently delete a suspect message, hold down the SHIFT key and hit DELETE.
