from an above post:

"http://security2.norton.com/ssc/hom...MQCKMRKRFPECDME and do a scan of your hard drive for any known virus and backdoor program. Norton also has removal tools for a specific virus. Take these steps and you are on your way to securing your box."

->you can use that security analyzer, but be forewarned: it will undoubtdely advise that your systems are " AT RISK " if you aren't using THEIR product. After all, they are a business. I would suggest using that analyzer, AND search for OTHERS (either on an engine or better yet within AntiOnline Forum). You may want to use more than one, to get a sort of 'average' of your overall exposure.

->I don't know what OS you are using, but you can also search within the forum for general options on how to configure your computer for better overall security as a BASIS to which freeware can ADD some security. (For instance, disabling file sharing and whatnot, and setting account policies.)
