Shall I clear out my cache

There are good and bad points to clearing or not clearing out your web browser’s cache.

Advantages to Cache

  • When you browse a website for the first time your web browser contains details about the website in a file called cache, if you browse on that same website the browser will bring up the website a lot faster basically given the user a speedier web experience

The drawbacks to cache

  • In some instances, the browser doesn’t display the up to date version of the site
  • Over time it starts to slow down your pc/laptop/mobile keeping a lot of junk memory
  • Some other website can read your cache and start targeting you with ads, in some worse case scenarios your browsing history is sent to a 3rd party server

For best practices clear out your cache once a month alongside a virus scan

Below are some links listing some steps for clearing out your cache for mobiles and desktop browsers

FBI wants you to reboot your router

In the past few months, there has been a malware threat called VPNFilter, this malware has the ability infiltrate some home user routers and cause it to be a part of a collective to cause a DDOS (Denial of Service) attack on specific websites causing that website to go offline.

The other thing that this malware target is none secure web traffic that the user views and inserted malicious code to web the traffic enabling it to spy on your previously viewed pages and gain access certain unsecured data and pages and pass it on to a centralized server

Below there is a small example of the affected 500,000 routers listed

Asus, D-Link, Huawei, Linksys, Microtik, Netgear, QNAP, TP-Link, Ubiquiti, Upvel & ZTE

The reason why the FBI is asking users to reboot their routers is that they have gained access to the main server that was doing all the collecting this data.

We at GT-systems encourage our users and clients to always browse the internet on secure websites and always use 2FA (2-factor authentication) for logins

Don’t Rely On Your Antivirus

In this day in age, we rely so much on our antivirus to protect us from all the nasty virus that lurk on the internet, but no antivirus can protect your system 100% of the time.

Recently we at GT-Systems have been receiving reports of a new virus a variant of the ‘Ransomware Virus’ that crippled the NHS in 2017 called ‘Hermes 2.1 Virus’ this also holds your files to ransom by encrypting it.

If you find yourself in this position and all your files are indeed encrypted finding a solution is very difficult, the attacker will normally ask for large sums of money that needs to be paid in a form of cryptocurrency to receive a key to unlock the files, please be aware that this method doesn’t always work.

Put some steps into your daily or weekly routine by backing up your data, a very simple way is to plug in an external hard drive and simply copy from your computer and paste it onto the hard drive.

Another option is to take full advantage of your free cloud storage if you have a Gmail or Hotmail account, simply sign into your account via the web and navigate, for Gmail customers head over to your ‘Google drive’ and for Hotmail customers head over to your ‘One Drive’ area, if you find that the free storage is not big enough each of these vendors will charge you a tiny monthly fee to increase the storage

For those who want a little more automation there are vendors out there that will have solutions and software to fully automate this process, but as always there is a significantly bigger monthly payment.

We must say to ourselves if we lost our files can we continue working or we’ll never see those precious memories again.

Remember 3 steps of backup

  1. 3 different copies
  2. 2 different mediums
  3. 1 offsite
