Symantec is well known for making security products (they also use the Norton brand for home products). A serious flaw has been found in some of their products including Norton AntiVirus, Norton Internet Security, Norton SystemWorks and Norton 360.
The flaw is in an ActiveX control that gets installed on the PC (the control is called SymAData.dll). This control is normally used for their AutoFix tool, however it was discovered that it can be exploited by adding some malicious code to a website. The exploit allows someone to take over the computer (generally a bad thing).
Two ways to fix this problem are:
- Engage in an online chat session with Symantec’s technical support team
- Download the patch from Symantec’s website, https://www-secure.symantec.com/techsupp/asa/install.jsp
Earlier we wrote about problems with ActiveX and suggested you disable it.
