use common sence- It’s always better to err on the side of safety. If you’re unsure about an attachment, delete it. Especially if it’s from a source you don’t recognise. If there are tempting animations on a site that look highly unprofessional, don’t download them.
scan floppies before using-This is always important, but especially if you are using the disk to carry information between one computer and another. You could easily pick up a virus from an insecure network and introduce it into your system. Running a virus scan before launching any of the programs on the disk will prevent infection.
Do not share floppies- Even a well-meaning friend may unknowingly pass along a virus, Trojan horse, or worm. Label your floppies clearly so you know they’re yours and don’t loan them out. If a friend passes you a foreign floppy, suggest an alternative method of file sharing.
Do not boot a floppiedisc- Floppies are one of the most common ways viruses are transmitted. If you are using a floppy while working on your computer, remove it when you shut the machine off or the computer will automatically try to boot from the floppy, perhaps launching any viruses on the disk.
Do not download programmes from internet web- Unreliable sources such as Internet newsgroups or Web sites that you haven’t heard of may be willing providers of viruses for your computer. Avoid downloading files you can’t be sure are safe. This includes freeware, screensavers, games, and any other executable program - any files with an .exe or .com extension, such as coolgame.exe. Check to see if the site has anti-virus software running on their side. If you do have to download from the Internet, be sure to scan each program before running it. Save all downloads to one folder, then run virus checks on everything in the folder before using it.
