Are you being bugged?
To find out, the first step is to consider carefully whether you are sufficiently interesting to warrant surveillance. If you’re a crook, a cheater, or a keeper of political or corporate secrets, the answer may be yes...
Consider also whether that gift from a business acquaintance could be a Trojan paperweight or Dumbo-eared desk clock. Maybe pass those along to Goodwill and, if you have any lingering doubts, call in a pro to execute a “bug sweep.” more
