You can open the .exe file on a floppy disk and scan it before you open it. I never open .exe files that are sent to me unless I have received word from the person sending it that it is coming. I usually verify it with them first before opening it. And then I think it over very carefully. I never open any .exe files with cute names.
Viruses are a frightening internet reality.
From my travels on the internet, the two most talked about are Norton Anti Virus and McAfee's Anti Virus software . If you don't have an anti virus program running then go to Housecall , an online virus scanner about once a week. This is a great tool and it's free. Housecall is very up to date with the latest viruses and virus fixes. Find a good Virus newsletter and subscribe.
