You may recall me mentioning Virus Total, this is a priceless service that allow you to upload a file and have it checked by many different antivirus engines within seconds. Excellent if you are suspicious about a file, or just if you want to be sure that the file you just downloaded is clean.
Well I did not mention another neat feature from Virus Total, a “send to” addition to Windows right click options. Once this is installed you can right click on ANY file and have it uploaded to Virus Total for analysis easy and painless.
