Ok here are some tips:
From now on... Use Firefox... and before you go on a pr0n spree, you must configure Firefox to save NOTHING!!!!! Make it block all popups, and have automatic software download disabled.
Have a realtime A/V scanner running at all times... Because firefox cannot stop malicious jar files.
Also to make sure that the average joe schmo does not revive dead files.... Just download, Killdisk.. That will prevent the average noob from retriving any files... And if you got the NSA,CIA,FBI,KGB, or * insert any 3 letter goverment agency * on your a**..... Just take the drive out in your backyard.... Take a hammer and beat the HD to a messy pile of scrap... Take those pieces and spread the pieces over a 10 Sq mile area and MAYBE you might get away with it.
