I'm going to be controversial here - Chrome is hands-down the best browser around. If you agree, then you'll want to use Google's browser wherever you can. whether at home or in work. If you have a business, or manage a company network, then you'll need Google Chrome for Business, the version of Chrome specifically tailored to networked organizations.

Apple recently announced that from March, apps submitted to the Mac App Store will have to employ 'sandboxing' to be accepted. But what does this mean for you, the end user?

Sandboxing basically puts a safeguard between the applications you've installed and OS X. It should ensure Mac apps are less likely to damage OS X because it limits the amount of interaction they can do with it. This means that the most critical parts of OS X are protected from infection by apps you install - hopefully meaning less major crashes or fatal errors in OS X itself.

This is an understandable move by Apple. Although Macs are still much more resilient to infection than PC's, as the number of Mac users grow, so will the number of Trojans and viruses aimed at it. Also, the fact that OS X has to use vulnerable plugins such as Java and Flash via browsers such as Firefox and Chrome means that certain backdoor vulnerabilities need to be closed.

There are some potential complications for end users however. For example, if an application  needs to establish a connection to the internet or interact with another program, the fact that it's been sandboxed may prevent or complicate this. Of course, if the developer has done their job properly and Apple implement sandboxing correctly within the App Store, it shouldn't be a problem and you should notice no major difference in the functionality of your apps.

For developer's, it's more of a headache. It means more work in specifying exactly what their applications can and can't access. There is also a concern that it will lock both developers and users into the App Store: will OS X eventually only accept apps that have been sandbox approved in the App Store first for security reasons?

But initially at least, it should mean a safer OS X experience, better performing apps and less application conflict issues.

Have you been accused of sending spam to your friends? In this post I'll try to explain why that might be, and what you can do about it.

Before we start, if you are accused of spamming your friends because you are forwarding 'send this message to 20 of your friends if you want eternal happiness' emails… you ARE spamming, so stop it!

But back to real spamming problems...

Case 1: You can see spam in your own Sent Mail folder.

This is the worst case scenario! The security of your email account has been compromised, and possibly even your computer too. There are a number of explanations:

• Phishing: someone has caught your email password through a fake website where you have entered it.

• Local theft: someone has accessed your computer in person, or you may have left your account signed in on a public computer

• Virus or key-logger: malware is always getting cleverer when it comes to stealing your information.

• Server hacked: if someone hacks your email server, they could retrieve passwords.

Whatever the reason, here is the solution:

Protecting your private information on your computer is important, especially if you share it with someone else. The best option is to have separate password-protected user accounts on the system, so that each person can only access their own documents and files. But if you share the same account, there are other ways to keep your data safe from prying eyes!

One of them is using Windows' own built-in protection system to block access to certain folders. In Windows XP, all you need to do is right click on the folder you want to protect, select Properties and in the Sharing tab, tick the Make this folder private option. If your Windows account doesn't have a password, the system will automatically ask you to create one.

In Windows 7, go to that same folder menu (Properties) and click the Sharing tab. The options under Advanced Sharing and Password Protection will let you configure exactly how you want to share your data, in terms of who can access what.

Protecting your computer from malicious software is the first step that users should take. Norton is a long running producer of security software and has now released the 2012 versions of Norton AntiVirus and Norton Internet Security. Both programs feature substantial changes and improvements from their predecessors.

Norton Internet Security 2012 is an overall system protection program featuring more comprehensive defense than Norton AntiVirus 2012 on its own. With Norton Antivirus 2012, users will protect themselves from viruses and spyware, but not their online identity. Users who are are only concerned about virus and malware protection should look at Norton Antivirus rather than Norton Internet Security 2012.

Kaspersky Antivirus 2012 is one of the most powerful virus prevention suites on the market. As with many antivirus solutions, though, there is a temptation to set it up as quickly as possible, never exploring the more advanced options available.

It's worth delving into the settings menu in Kaspersky Antivirus 2012: it has lots of different options for managing the way the application runs and what it does to your system.

I’ll explain some of the useful features in Kaspersky's Advanced Settings. This menu can be accessed by clicking the  Settings tab at the top-right of the user interface, then clicking the Advanced Settings tab, which is the fourth and final in the row of icons (it looks like a box).

Detect Threats and Exclusion Rules

The first option in the settings menu allows you to define the type of threat you want Kaspersky to look for. Besides viruses and Trojans, the software can scan for adware, auto-dialers, and strangely created compressed files.

It’s also possible to exclude certain applications from these scans by clicking the Settings button in the Exclusions section.

Good news for those that want a hard copy of Lion in the event of catastrophe - Apple have decided to issue a Lion Recovery Disk Assistant which allows you to create a backup partition of Lion on any external hard drive. All you need is a USB stick or external drive with at least 1GB of space on it.

The tool will allow users that suffer total hard drive failure to recover their system. Currently, Lion creates a recovery partition on your hard drive when you install it but that's not much use to you if your entire hard drive fails.

The new Lion Recovery Disk Assistant will allow you to reinstall Lion, repair the hard drive using Disk Utility, restore Lion from Time Machine or just browse the web with Safari. Note however that it does not create a Lion recovery USB stick/DVD - it simply creates a partition onto which you can redownload Lion from the Apple store and restore Lion to your system.

To use it, simply download Lion Recovery Disk Assistant, connect an external drive or USB stick to your Mac, launch the assistant, select the drive where you would like to install, and follow the on screen instructions. Voila, you've got a hard copy of Lion to restore it from in case of hard drive failure.

Note that when the process is complete, the new partition will not be visible in Finder or Disk Utility. To access Lion Recovery, reboot the computer while holding the Option key and then select Recovery HD from the Startup Manager.

Most of us carry a smartphone or laptop everywhere we go: the office, the coffee shop, the library. And more often than not, we don't pay enough attention to our valuable gadgets - or we just leave them unattended for a moment. While keeping an eye on your belongings at all times is the best way to prevent anyone from stealing them, having an extra layer of security is not a bad idea either. There are apps to track stolen laptops and mobile phones with which you can find your missing gadgets, and also erase their content if necessary. Here are some of the most popular ones:

Track stolen laptops.

The most popular tracking app for stolen or misplaced computers is Prey. Prey is an open-source utility that uses WiFi spots and geolocation to find your laptop. All you need to use it is install the client on the computer and create a user account on the Prey website. If your computer disappears, log in to your Prey user account and mark it as "missing". The program will start sending highly detailed reports with loads of information: active apps, network connections and desktop snapshots - you may even catch the burglar's face with the laptop's built-in camera!

With iOS 5 apparently to be released soon, is it really necessary to update to 4.3.4? Apple would of course say yes, as this update fixes a well-known security flaw in Safari that allowed 'maliciously created PDF files' to potentially corrupt your iOS device.

Most of these malicious PDFs were actually used to pry open iOS 4 for jailbreaking, and it is exactly this that Apple want to stop. In that sense 4.3.4 is a failure, as it has reportedly already been jailbroken!

The 4.3.4 update is compatible with all iOS 4 devices, and weighs in at just over 400MB. Disappointingly, there are no additional improvements other than the security fix. I guess Apple are saving all their practical usability improvements for the iOS 5, which is probably out this September. Better notifications will have to wait...

Google+ may be more than "just" a social network, but it can be used in in a similar way to Facebook, and many people want to join precisely because they want a change. Facebook has suffered a number of privacy scares as it has grown, so how does it compare with new kid Google+? Let's take a look at the  privacy options of both social apps.

Privacy Settings:

Facebook's privacy dashboard has a neat table that shows you who can see what. Click Customize and you can edit these settings. You can choose to share things with just you, friends, friends of friends or specific people. You can also opt to hide certain categories from specific people. Here you can also preview your profile as it appears to any of your friends.

The Google+ privacy settings page is much longer, but every segment is clearly explained. Editing your settings takes you to your profile, letting you see exactly which part of your profile you are altering. Google+'s Circles means you choose who can see your posts and updates as you make them, giving you much greater control.

While their approaches are different, I think both are good attempts at making privacy and sharing settings accessible and user friendly.

Security app extraordinaire, avast! Free Antivirus, has been updated to 6.0.1203, bringing with it a host of new features that definitely improve the performance of the most popular anti-virus on Softonic!

So what's in this version? Well, on a technical level, the app is now more compatible with Windows Vista service packs 0 and 1, and a firewall issue with uTorrent has been solved. Add that to the resolution of a memory-eating problem with Chrome, and bunches of users are going to find using avast! a whole lot more comfortable.

Advanced avast! users are also going to benefit from improvements to the CommunityIQ sample submission process, one of the aspects to the app that make it as powerful as it is. There is also a raft of improvements and stability fixes for avast!'s sandbox module, making your test installs and technical tinkering a whole lot safer!

According to an announcement on their blog, Facebook has implemented facial recognition technology that's going to make photo tagging much easier from now on. This new feature has actually been available for a few months, but is only now being rolled out to all countries. Thanks to facial recognition, you shouldn't have to type in your friend's name every time you want to tag them in a picture - Facebook will automatically suggest it to you, as long as the system is able to identify their faces.

But not everyone is happy with this new feature. If you don't like being tagged in photos, this is just one more thing you have to worry about with your Facebook account. Luckily for you, disabling facial recognition  is quite easy. Here's how do it:

1. Open Privacy settings from the drop-down menu in the top right corner of your Facebook account.

2. Click the Customize settings link.

3. Scroll down until you see the Suggest photos of me to friends (under 'Things others share') and click the Edit Settings button.

4. Facebook will open a new window with a brief explanation about this new feature. Simply select the Disabled option in the drop-down menu and you're done.

Of course, disabling this feature doesn't mean your friends can't tag you. They can still do it by entering your name manually. It just won't be as easy as Facebook wants it to be!

In an unofficial admission that Mac users are facing malware attacks, Apple have rolled out a new Safari security update for which should protect users from the recent spate of malware attacks which have targeted Mac users. Apple have issued a note with the update saying:

For the protection of our customers, Apple does not disclose, discuss or confirm security issues until a full investigation has occurred and any necessary patches or releases are available. To learn more about Apple Product Security, see the Apple Product Security website.

Apple are obviously reluctant to confirm that OS X is now becoming increasingly susceptible to the types malware attacks that Windows users have had to put up with for years. Refusal to acknowledge the hundreds of cases of users experiencing malicious popups over the past few weeks prompted Wired magazine to ask whether Apple are in denial about the so called "Mac Defender" malware attack.

To ensure that your Mac is protected, click on the Apple logo in the top left-hand corner of OS X and select Software Update.

If you don't like targeted adverts, or the idea that some websites will use your browsing habits for marketing profiles, it is possible to stop them. Here are the best add-ons for Firefox that make sure websites can't track your internet activities:

TACO

TACO (Targeted Advertising Cookie Opt-Out) prevents over 100 different online advertising networks - including Google, Yahoo and Microsoft - from displaying highly targeted advertisements using the detailed information on your web surfing habits. TACO works by placing 'opt-out' cookies into Firefox which prevent the services from targeting you with ads. Although its a pretty drastic tool - TACO will clear-out all of your existing cookies except the 100 it places in Firefox meaning you'll lose a lot of your stored passwords, filled-in-forms etc - its very effective at stopping you becoming a victim of targeted advertising.

BetterPrivacy

BetterPrivacy is a Firefox add-on that deletes a relatively new type of tracking cookie known as local shared objects (LSOs). This type of cookie, known as 'super cookies' are particularly harmful because they store a huge amount of information and, crucially, can't be deleted like a normal cookie. BetterPrivacy finds the folder on your hard disk where the LSOs are stored and when you finish a session, deletes any it finds there. Again, it deleted everything in your LSO folder - including saved passwords etc that you'd rather keep - but you can preserve certain LSOs on a safelist.
