Technical Details

Trojan-Downloader:W32/Small identifies one of more than 370 variants (as of June 28 2004) in this large malware family. The main characteristics of these programs are:

  • They are very compact (a few kilobytes long).
  • They silently download and run executable files on a user's computer.

Many variants are compressed (bya variety of file compressor programs) to reduce their size and hide their contents from the user.

Some Small variants download adware, spyware and searchware (third-party search plugins); others download trojans and backdoors.

Small variants are often silently installed on a user's system via a driveby download when the user visits a malicious website.
