Running SEP version 11.0.6005.562 under my employer's corporate license. Recently started getting these 'pop-up' alerts in the system tray (lower right corner). Address is DNS Server for Time Warner Cable, but they say to contact Symantec for "updates". I'd like to upgrade to the latest version (12.1?), but I don't know what the "M" serial number is for my installation. Can I upgrade without it? Can the install validate my current installation?
Also, when using Chrome browser, I'm getting a *lot* of pages timing out (not appearing). This problem seems to have coincided with the "blocked IP Address" tray alerts. Seems like my machine is under attack.
OS is Vista Home Basic Service Pack 2. Symantec definitions and OS patches are up-to-date.
