Safety and Security on your Computer Presented by Joy Watson
“You’ve Got Mail” – but who is it really from? Does Tom Hanks just want Meg Ryan’s bank password?
A few facts of connected life… In general terms – there is no such thing as privacy – every electronic contact leaves a trace. Once an image or comment is posted online, you lose control of it – forever. Many people find hacking highly attractive. Synchronised devices mean your data is accessible online from anywhere – easier to hack! No such thing as “free” software.
Not everyone is who they claim to be online Maybe you aren’t either?! Careful. Remember Captain Mainwaring: “Don’t tell ‘em your name, Pike!”
Where do I start? Does anyone else in your home know your passwords/PIN numbers/Secret Word(s)? Do you know anyone else’s? (It’s OK to know your child’s) Have you ever encouraged your child, relatives or partner to “log on as you?” Fact :- in 145 Primary school visits, at least 40% of year 5s know mum or dad’s PIN number. Fact :- 92% of year 10s say they know and have used Mum/Dad’s username, password or PIN number.
Do some snooping yourself! Legitimate surveillance Logs all internet activity Tracking someone else, teaches care with your own privacy Is your partner seeing someone else? Are your children accessing inappropriate content?
Even Linux and Mac computers are at increasing risk
Permissions: Giving away control Never give real name, date of birth, gender, address, phone number except when you have no choice. NEVER reveal PINs Use credit cards not debit cards online (increased fraud protection as well as free borrowing period) “Free public wi-fi” networks are not secure like your private home network should be - it may be the guy at the next table Avoid illegal music downloads, which may hide a virus Learn how to use security settings on social media like Facebook or Twitter ( & use an alias and/or fake birth date)
Back everything up first, especially your own work! Spring Clean Your PC – it’ll run faster too
6 Essential Protections…. 1 good, all round anti-virus, anti-spyware, anti- malware package installed and regularly updated. Windows Update configured to download and apply updates regularly. Windows Firewall on. Check browsers and main software = latest versions Clear your browser cache / delete Internet history Turn off wi-fi on your Router if your devices connect physically to it - OR use a WPA2 secured home wireless network. (See your manual) Uninstall what you never use (especially free stuff)
Use a free PC optimising program (keep it updated)!
Other Stuff You Should Do – Demonstration required (can’t show now) Enable ActiveX filtering (Tools menu in Internet Explorer) Block Popups (Tools/Options/Content in Firefox) Disable Tracking and suspect websites (Options/Privacy and Options/Security in Firefox) Disable Ads (Pop-Up Blocker, Ad Block Plus etc.) Disable Flash media (Control Panel, Flashblock etc.) Google how to stop Videos Auto-playing in web pagesstop
Try and find out its NAME, maybe from any error messages you are getting. Getting rid of Viruses
“Windows Media Codec Pack” allows viewing of many Video formats Example: Sometimes free programs are great… but take care. Watch for and un-tick add-on programs like Toolbars you DON’T WANT bundled with your download. In this case the virus is OpenCandy, not serious. We want this free non-Microsoft program but we don’t want the threat.
Full details of the virus now made safe It can now be deleted from the Virus Vault
Investigate suspicious folders not in list of installed programs Search for its name online and if dodgy, try to delete some of it Scan whole computer occasionally – Trojans may exist
Find how to remove it (from another PC if need be) from reliable websites (e.g. Norton, BitDefender, AVG, etc.)
If you still have a virus… It cannot be removed because it’s running! Try to stop malware process running from Task Manager If antivirus program not working, try rebooting in SAFE MODE (F8), and run Norton Power Eraser (free) from disk or Symantec’s website
If still stuck, try System Restore Go to Start Button Right-click “Computer” Select “Properties” Click “System Protection” Then “System Restore” (N.B. Check before disaster strikes that protection is turned on for your C: drive, and that space for restore points is 1-10GB, not zero)
Another virus removed, haha, got you back! Fake Flash Player UpdateSorted out!
