You may want to add superantispyware http://www.superantispyware.com/ The free version is non resident (on demand) The paid version has a trial period and I believe it reverts to the free version afterwards.

There is a newer version of sygate ( I know it’s unsupported) can’t recall the exact number, but it doesn’t work to well on 98se or me. So if you are going to continue using sygate, keep the version you have now.

you will have to set the proxy for webshield manually
