I'm no big fan of Symantec. Was a contented user around 2001 / 2003, and ditched them in 2004. But, when I was using both their "internet security" and Spybot, Spybot's system startup list descriptions used to list some Symantec programs as malware instead of the genuine thing. (It's been a while, and I don't remember exactly what Spybot said about which program).
I'm sure the computers involved weren't infected and the files Spybot complained about were legit, so I can't blame Symantec for being a bit ticked-off.
Also, after I upgraded to their 2004 version it kept getting corrupted and forcing me to re-install. Changed to another company without ever tracking down what caused it, but I could never get rid of the faint suspicion that maybe my overnite scheduled Spybot scans were nuking something they shouldn't.
I registered just to respond to Lord Cobol. Sir, did it ever occur to you, that Spybot S&D was telling you that something had perhaps infected your Norton's product, and during it's cleaning, yes, it's possible that in order to get rid of the infection, it had to get rid of some infected files in that particular folder. HOWEVER, Spybot S&D DOES NOT delete anything unless YOU THE USER tell it to. It also makes a quarentine of the files and you can..or could have, restored them if needed...
Norton products are so easily targeted by so many viruses and other unwanted and infectious things out on the net, that their products usually don't even detect them and continue to "work" as if nothing is wrong with them. You would do well to just uninstall any Symantec products you have now, then to wait until they become infected and then blame another program when it tries to clean them up...
Now, back to the topic at hand, I say detect any and all Symantec products, and recommend to the user that they should, if they want to keep their computer safe, uninstall the Symantec product(s).
