OS(es) Affected: Windows

W32.Flamer is a worm that circulates through removable drives. W32.Flamer also opens a back door on the affected computer and may steal personal information from the targeted machine. W32.Flamer tries to avoid detection by anti-virus programs by saving its complex code in .OCX files, not usually checked by anti-virus programs in their default configuration. However, if W32.Flamer detects the presence of McAfee's on-access scanner named McShield, it saves its code in .TMP files instead.
