First, keep in mind that there are two sorts of files in the PC World Downloads library:
We do receive many reports from users whose security applications mistakenly report spyware or Trojan horses in files downloaded from PCWorld.com. Please note that antivirus, antispyware, and other security applications vary widely, and each program is based its own definitions. Some definitions tend to misidentify certain elements in downloads as "spyware" or "Trojan horses" when no such items are included. Actual spyware and Trojan horses are unlikely to be contained in files downloaded from PCWorld.com. However, if you are certain your security application has reported such a problem correctly, please report it to webmaster at pcworld dot com.
