Generally speaking, the single most important thing you can do to keep your computer safe is make sure your operating system and apps are up-to-date. Because though it looks like nothing has changed afterwards, below the surface every update is fixing bugs and holes that can be taken advantage of by hackers. Modern computer systems are so wildly complicated that it is basically impossible for developers to build a completely secure system. However much you test and try, hackers and people with bad intentions will comb through and look for a bug or a hole they can use to access your private data.

The most simple attack is a Bruteforce attack of simply going through and trying every single combination of letters and numbers to, for example, guess a password. This is why you can only get the passcode on your phone wrong three times before it locks up. Phishing isn’t so much clever technology, but is a psychological trick to persuade you to hand over your details. If you browse a website that has http and not https, and you’re on a public WiFi, anyone on the same network could read every word being sent to your phone or computer. This is called A Man In The Middle attack. Finally there is Malware. This is software through which hackers can run their own code on your computer, then they can do whatever they like.

This used to be a really, really bad problem. But today, both Windows and Mac are more locked down than they used to be. So though the threat of hackers is real and scary, the good news is that the good guys are getting better at fighting them. But that doesn’t mean we should be contented. The best way to keep your data safe is to remain careful where you click. And, of course, make sure all of your apps are up-to-date, so they have all of the latest safeguards to keep you safe.

A team of well-known developers have built a security tool, Scanguard™, which they believe will be the last piece of software consumers will ever need.

Product Manager, David, from ScanGuard, explains, "The software can increase the security immediately by distinguishing any hidden dangers or online tracking cookies. Also, it discovers and removes unnecessary files and cached memory—the files that can make your PC run slow. To have perfect performance and keep your computer secure, schedule the scan to run every 7 days. It roughly takes 10 minutes to fully analyze your system."

"People already love the system. Our plan is to give as many free scan licenses away so that it gains widespread use until we think that's enough for us to start charging. If you own a Windows Computer then you are allowed to have a free security scan. We advise users not to hesitate and try it cautiously and bravely before it's too late. We feel good knowing that we're helping make things faster and more secure for our customers,'' he continues.

The Scanguard™ free plan will, offer you a version of the software which will monitor your PC in full for threats (威胁)，unwanted software or potentially dangerous tracking cookies. If the software finds out threats you can remove them from your system by hand now or pay for it to have the software do the automatic job about them.

Once you have downloaded the software you can also have free licenses for all of your devices, including your,Office & Home PC, Smartphone & even Tablet. It's so convenient! It’s no surprise that thousands of computer owners are taking advantage of this approved security system to keep themselves and their devices safe.
