Money mensch: Protect yourself from cyber criminals

By Martin Lewis, December 9, 2009

Computer hackers are everywhere. It is more important than ever to protect yourself. If you don’t, and your bank account is defrauded, it can mean you are liable to pay for it. Luckily, you can get professional anti-virus software for free. This time of the year is one of the worst for viruses, as many of us are shopping and checking bank accounts online. Viruses are not easy to spot; they can be passed on in emails or even by visiting otherwise reputable websites.

If your bank account is defrauded, provided you have taken all necessary precautions, it is your bank, not you, which must foot the bill.

Step 1: Keep your computer updated

Most computers are run on Microsoft software, and that already has some built-in protection; crackers and fraudsters often try to break through this to exploit weaknesses.

As it learns about these, Microsoft issues updates, so make sure you’ve ticked ‘download automatic updates’, which you’ll find under ‘system’ in ‘control panel’.

Apple Mac users have slightly less to worry about, as there are not as many viruses lurking out there, but they too should make sure their machines are updated. If you are a high-tech Linux user, you are probably more than capable of looking after yourself.

Step 2: Ensure your firewall is switched on.

Most computers include their own firewall software (or hardware), which prevents a host unbidden nasties hitting your computer.

The best way to describe a firewall is as the computing equivalent of a border fence stopping things sneaking in the wrong way. While anti-virus software is the border guard, question each bit of data that legitimately passes through to check there’s nothing hidden on it.

Even if you are not techie, you should be able to find it in you computer’s control panel or options and check it’s turned on.

Step 3: Free antivirus software

Paid-for protection is likely to cost you roughly £50 a year, but there are ways of protecting yourself for nothing. There are four mainstream free professional anti-virus software packages for PCs:

Microsoft Security Essentials, launched earlier this year is completely free to users of ‘genuine Windows machines’ and is available for XP, Vista and Windows 7. As it is part of the windows package, many people will find it easier to use.

Avira Antivir. The free anti-virus software of choice for techies. It’s fast and thorough, but you’ll need some technical knowledge to get the most from it.

AVG Free and Avast. These have been around for a while and are very popular, though the new packages above are taking many of the current accolades.

Many of these companies offer free programs as a form of marketing; it helps build the reputation of the firms that produce them, which is useful for selling other programs, including corporate anti-virus software. Also, they want you to pay to upgrade to more fully functioning versions of the software. Yet these programs should be enough for most home users, providing you download the regular ‘virus bank’ updates, so they can detect the latest problems.

Alternatively, you may be able to get normally paid-for antivirus software for free for a year or so if you bank online. Barclays offer some customers Kapersky Internet Security, HSBC supply McAfee Virus Plus.

Step 4: Be aware of anti-spyware and adware

Anti virus software and a firewall should be enough for most home users. Yet there are other useful progams out there which can help.

There is free software that can protect you against spyware; in other words, it monitors programs you have chosen to download, to see if they are surreptitiously checking what you are doing on the computer and reporting it back. You can also counter adware, which is software that sneaks onto your machine and opens up adverts to try and sell you things, depending on what you are doing. It is also worth making sure you’ve got a back-up of important files online, on CDs/DVDs or perhaps on an external hard drive and see that your email is protected from unwanted messages, or spam, using a spam filtering program. Forfull list;

There’s free Office Software too. Perhaps the biggest of the lot is the free equivalent to the popular Microsoft Office progam. It is called Open Office and includes full word processing, spreadsheets, presentation software and more, and you can download it at no cost.

Although it does not have all the best bits of the Microsoft programs, it is probably more than enough for most home users, and they are compatible with most other programs of the same type, so you can share documents with other people

This software is developed under the ‘open source’ model, which means it is the result of collaboration between techies around the world who are keen to reduce giant corporations’ dominance. And similar is available for everything from analyzing data to 3D graphics modelling
