Do you think you have a virus?
Nobody likes malware, and its safe to say it doesn’t belong anywhere near your files.
Have you ever had something on your computer that you suspected was in fact a virus? Let me introduce you to VirusTotal… a free online virus/malware scanning engine that will allow you to upload or email a suspect file to find out how bad it really is. It submits the file to 32 companies for their own look, and then gives you a detailed report quickly there after.
If you are ever in doubt about a file again… just take a moment and upload it to http://www.virustotal.com/ and rest assured that it won’t harm your computer.
