Scams of all kinds multiply on the web, from now classic Viagra to Windows pop up inviting you to clean your PC urgently. The organization of the culprits is gets increasingly sophisticated. Continue reading
If you constantly use your internet browser (especially Chrome), you will probably notice that the more tabs you open, the slower your machine gets. Each open tab consumes resources from your processor.
There are ways to pause unused tabs, such as The Great Suspender, but these are extensions that can cause other issues, even at the security level. Continue reading
For most of us, web browsers are an open window to the endless twists and turns of the internet. But these two-way dormers also allow the outside world to intrude, at times, sneakily into our privacy, record our every move on the web so as to understand our aspirations and influence our behaviour, not to talk of simply infecting our machines, by pure desire to harm or to sell us a cleaning solution.

Remembering different passwords for the wide range of sites we visit daily is a real challenge. How many times did you not have to press the “forgotten password” link to generate a new one? Some services have noticed the aberration of the classic password and offer to authenticate via a code received by SMS or a push notification in a dedicated app. This saves you from constantly having to go back through email. This is the most secure technique, which is also found in the double-authentication process. Continue reading
A massive cyber attack struck the globe last Friday, affecting 150 countries and over 250,000 computers including those of major government organizations and corporate operations. This ransomware dubbed ‘WannaCry’ is fearsome because once it is activated on a device, it encrypts all the files so that they are inaccessible. At that point, it instructs the computer owner to pay a ransom in Bitcoin in exchange for unlocking their files.
So what can you do to make sure you’re protected against this vicious ransomware?
All in all, staying vigilant on the web is the most crucial wisdom. Hackers around the globe are always looking for new ways to make trouble in return for their almighty dollar, so don’t make their lives easy. Always think twice before clicking and make sure you are using updated versions on your system. If your device becomes affected, get in touch with Europol for assistance in your native language.
Malware is short for malicious software, meaning software that can be used to compromise computer functions, steal data, bypass access controls, or otherwise, cause harm to the host computer. Here are explanations on the five most observed types of malicious programs to watch out for:
Adware is a form of financially-supported malware that usually presents itself in the form of unwanted advertisements displayed to a user. The Internet is filled with these types of programs that can hijack your PC for profit. Most of them are hidden inside so-called “free” downloads and pop-up ads that forcibly install software on systems with active vulnerabilities.
This type of malware covertly collects information and transmits it to interested parties. Information gathered includes web sites visited, browser and system information and IP address. Spyware does not have any infection mechanisms and is usually dropped by a Trojan. A hacker uses spyware to track your internet activities and steal your information without you being aware of it. Credit card numbers and passwords are the two most common targets.
Just like the trojan horse from ancient greek mythology, this type of malware is disguised as a safe program designed to trick users, so that they unwittingly install it on their own system, and later are sabotaged by it. Normally, the hacker uses a trojan to steal both financial and personal information. It can do this by creating a “backdoor” to your computer that allows the hacker to remotely control it.
Like a virus that can infect a person, a computer virus is a contagious piece of code that infects software and then spreads from file to file on a system. When infected software or files are shared between computers, the virus then spreads to the new host.
Similarly, worms also replicate themselves and spread when they infect a computer. The difference, however, between a worm and a virus is that a worm doesn’t necessitate the help of a human or host program to spread. Instead, they self-replicate and spread across networks without the guidance of a hacker or a file/program to latch onto.
