Hello, as you can see I'm new to this forum but not new to forums in general. I am not sure if this is the correct area to post this but I did not see an area specifically for virus threats. I may be overly suspicious, but I believe my computer may have a virus that Symantec is not picking up. It seems like it only effects my internet browsers though. To give a little background:
OS: Vista Home Prem 32-bit (current on updates)
Norton: Internet Security 2009; Antivirus 2009 (both up-to-date)
Internet Explorer 8 and Google Chrome 3.0.195.38
No other antivirus or browsers installed
Ask if you need any other info on my setup
Issue: Seemingly randomly, both IE8 (opened normally and "Without Add-ons") and Chrome will shut down with an error from DEP saying "Data Execution Prevention - Microsoft Windows. To help protect your computer, Windows has closed this program." I thought it was weird that IE8 just started closing one day and then I installed Chrome and almost immediately it started closing because of DEP. They shut down at random and I am unable to duplicate it because it does not happen specifically on one site or by clicking a specific link. DEP does not allow me to add either browser .exe to the DEP "exception" section under "Advanced System Settings>Advanced>Performance-Settings>DEP". The DEP does not effect any other program I have ever run on this computer so I have to assume there could be a virus somewhere that Symantec is not picking up, has not added to their Definitions yet, or one of the sites I visit regularly has an active virus. Sites I visit regularly include Facebook, MySpace, Google (and branches of Google), Hotmail, Gmail and USAA Banking. I do not visit "dirty" sites and do not click on popups nor do I fall for the common "Your computer is being attacked. Click here now to start a virus scan" type popups or pages. I have noticed this complaint on both the Google Chrome and Microsoft forums but neither has been solved. After using the Search I didn't find much and I was just curious if Symantec or any Symantec product users have experienced the same or knew how to fix this? Thank you all so much!
