I’ve been very fortunate to have never been hit with spy/ad-ware. I’ve always been careful, and I’ve tried to teach my wife what actions are smart and which ones are not. Last night, however, I was looking for some information and ended up downloading a file from a shady website. After scanning the file and finding no viruses, I ran the executable. How stupid. It immediately began installing adware and my antivirus app began showing warnings of a trojan being installed.
