31 31 21 September 2009 Wrong! Things to watch out for…

32 32 21 September 2009 1. Anti-Virus doesn’t stop everything

34 34 21 September 2009 Yeah, but how do they infect me? (or how to viruses get around anti- virus?)

35 35 21 September 2009 How do they do that? Vulnerabilities Threats Value

36 36 21 September 2009 Popular Searches

37 37 21 September 2009 The old classic - Email attachments Published with kind permission from Mikko Hypponen Chief Research Officer. F-Secure Corporation

38 38 21 September 2009 Cute yet a little bit rubbish web sites… Published with kind permission from Mikko Hypponen Chief Research Officer. F-Secure Corporation

39 39 21 September 2009 How can I tell something bad has happened? Maybe…. nothing Or….

40 40 21 September 2009 Your computer is infected with 182 viruses – click here to fix Source: Washingtonpost.com

42 42 21 September 2009 Even more scareware …looks convincing doesn’t it? Source: Washingtonpost.com

43 43 21 September 2009 What can I do? 1. Prevention… Buy & use the most up to date anti-virus you can. Use spyware software such as Malwarebytes. Don’t trust anti-virus alone. Mix up your browsing, maybe use Firefox? Do you really want to open that email attachment? Those cute eCards might not be so cute. Never, ever, click here to fix your virus issues. Take some time to read up how to set you computer up.

44 44 21 September 2009 If you do get a virus 2. Cure Disconnect from the internet – take your cable out. I’d power off. Reboot into safemode Run anti-virus (again). Download and run Malwarebytes Antimalware & Superantispyware Some good information to print out at: –http://www.bleepingcomputer.com/virus-removal/remove- windows-police-prohttp://www.bleepingcomputer.com/virus-removal/remove- windows-police-pro –http://www.dslreports.com/forum/cleanuphttp://www.dslreports.com/forum/cleanup Reinstall ? (boot and nuke first).

45 45 21 September 2009 2. Scams

46 46 21 September 2009 Nigerian 419 scams Good Day, My name is Dr William Monroe, a staff in the Private Clients Section of a well-known bank, here in London, England. One of our accounts, with holding balance of £15,000,000 (Fifteen Million Pounds Sterling) has been dormant and last operated three years ago. From my investigations and confirmation, the owner of the said account, a foreigner by name John Shumejda died on the 4th of January 2002 in a plane crash in Birmingham. Since then, nobody has done anything as regards the claiming of this money, as he has no family member that has any knowledge as to the existence of either the account or the funds; and also Information from the National Immigration also states that he was single on entry into the UK. I have decided to find a reliable foreign partner to deal with. I therefore propose to do business with you, standing in as the next of kin of these funds from the deceased and funds released to you after necessary processes have been followed. This transaction is totally free of risk and troubles as the fund is legitimate and does not originate from drug, money laundry, terrorism or any other illegal act. On your interest, let me hear from you URGENTLY. Best Regards, Dr William Monroe Financial Analysis and Remittance Manager [Phone Number Removed
