7: Stay questionable websites (e.g. porn, warez, hacking)
8: Poke excessive holes in your firewall by clicking "Allow" each time some curriculum requests access to the Internet (3)
9: Click directly on associations in send by e-mail post
10: Use file allotment or P2P programs
11: Use pirated programs

Things you SHOULD do
1: Use a non-IE or IE based browser (4)

7: Copy and paste URLs from send by e-mail post into your web browser

9: Set up a fixed backing regimin (10)(11)
10: Make fixed checks of your backing media to ensure it is still excellent (12)

4: Avoid texting speak or "l33t speak" (16)

(1) Alas now and again this is unavoidable, so only use IE when the site categorically will not work with any additional browser and you cannot get that in rank/service anywhere else, and only use IE for that one point site.
(2) Outlook and Outlook Express are very insecure, and in the end invite spam. The jury is still out on Vista's Windows Mail, but agreed Microsoft's history with send by e-mail programs, utmost caution is advised. Possible replacements contain Mozilla Thunderbird, Eudora, The Bat, and dozens of others.
(3) When it doubt over whether or not to allow some curriculum, use Google to find out what it is and whether or not it needs access to the Internet. Otherwise, denying access is the safest course of proceedings, since you can always exchange the rule later.
(4) On Windows your options contain: Mozilla Firefox, Seamonkey, Opera, Flight, Chrome, and Trip. I would personally urge Firefox with the NoScript extension for added security, but it the vital business is to pick one and use it instead of IE.
(5) AVG Free and Avast are unfilled if you need a decent free virus scanner
(6) XP/Vista's firewall is probably excellent sufficient for 99% of all Windows users, but additional options contain ZoneAlarm, Station Firewall, and Comodo. If you have a router with a firewall built into it, there is no need for any of the aforementioned firewalls to be running.
(7) Microsoft's usual system is to release security updates each second Tuesday of the month.
(8) Use of Windows Bring up to date on Windows operating systems prior to Windows Vista requires Internet Explorer, and is thus a valid exception to the "No IE" rule.
(9) Service packs must ALWAYS be installed. They frequently hegemony security updates that will ONLY be establish in that service pack.
(10) You can go with a full fledged backing curriculum, or austerely doubling-up vital records onto a CD/DVD/Enthusiasm handbook.
(11) I'd urge a tiered backing system. For model, you force have 5 rewritable DVDs, and each day you burn your backing onto a new disc. On the 6th day, you erase the disc for Day #1 for your backing, and so on so that you have manifold backups must one disc ever go terrible.
(12) Exchange rewritable CDs and DVDs approximately each 3-6 months.
(13) These dramatically boost the size of send by e-mail post (2-3X minimum) and clog up send by e-mail servers already straining to cope with the flood of spam pouring in daily.
(14) If you want to impart photos with friends/family, upload them to some photo allotment site like Flickr or Google's Picasa Web and then send people a link to that fastidious photo arcade.
(15) This is thorough to be the same as SHOUTING and many people find it to be hard to read along with greatly grating.
(16) Except the goal is to make physically look like a pre-youthful girl, or someone overcompensating for their yucky inadequacies, and you don't want people to take you from the bottom of your heart.
(17) Most REAL hackers are practically content to leave you alone except you make them take notice of you. No dinky modest software firewall or consumer grade router is vacant to keep them out of your system. So do not go to some hacker website or chat room and start shooting your mouth off except you're set to accept the penalty
