Just found I've had a dormant Finjan SurfinShield program on my xp hard drive that's been there for a long time. Version 5.7.01. I think I must have copied it over from an older pc prior to this one. It used to be a great little middleguard between firewall and a/v. Can I use it with xp? It's now up and running without apparent problems. But, am I going to have problems by using it? Should I go ahead and use it if it doesn't seem to interfere with anything?
