Encrypting private information, disabling potentially harmful scripts and cleaning up accumulated detritus are all ways to strengthen your security. The following downloads will help you to keep things safe and orderly.

Kruptos 2.0


Worried that someone may gain access to your most private files? Kruptos 2.0 uses powerful, 128bit encryption to scramble files so that only you can read them. It's particularly useful for USB flash drives and portable storage devices.

Kruptos lets you create self-extracting, encrypted archives and shred deleted files so that all traces vanish. It will even disguise the filename when you encrypt a file. Download Kruptos 2.0 here.

Transaction Guard


This is actually two pieces of software. It's a spyware detector and eradicator that monitors your system for spyware in real time – it then kills any it finds. It also introduces a 'secret keyboard' to ensure your secret passwords are not stolen online. Download Transaction Guard here.



When you surf the web, you leave a trail. Your PC swells up with temporary internet files, a history list, cookies and autocomplete entries. Windows itself constantly monitors what you do and records information about it. A hacker could gather a great deal of data about you from the stuff clogging up your PC.

CCleaner rids your system of all such traces, helping maintain your privacy and giving you back some of your hard disk space too. The first time we used this utility, it deleted a whopping 835MB of files. Download CCleaner here.
