Antivirus / Internet security products reviewed

 I've done technical tests of AV products in previous blogs, but this one is of my personal experience.

  1. Norton - generally slow
  2. BitDefender - good, but monumentally performance degrading, and features don't always work as advertised
  3. Avast - has always caused BSODs because of the network filter driver
  4. AVG - loaded with advertisements - do not recommend
  5. ESET - very lightweight load wet performant. High granular control esp over the firewall which does not interfere. Brower sandbox.
  6. McAfee - bloated, fragmented, slowly updated, archaic
  7. Kaspersky - one of the best, but no longer trusted by UK or US governments, and dropped by Barclays
  8. Webroot - all scanning is done online similar to how VirusTotal operates - so useless if there is no internet connection
  9. F-Secure - not bad
  10. Windows Defender - very basic
  11. Malwarebytes - poor detection
  12. Firewall products
    1. Glasswire - blocks rather than leaves requests pending

Not tried:
  • Trend Micro
  • Panda
  • Avira
  • Bulldog

Broadband providers reviewed

If going for a new connection I'd recommend going to Topcashback, Quidco, Hotukdeals or Compare the Meerkat for some very good deals and check the reviews.

Rated best to worst:

Hyperoptic: Excellent speeds and very good customer service

Zen: best service, very rarely drops out, great router, just initially pricey and may include hidden fees or different prices on the phone to their website.

Plusnet: Good but regular disconnections and waited a month just for them to cancel an installation

BT: Most of the time okay but a nightmare when you have problems

Virgin: Dropouts once a month and speeds aren't as advertised. They may still be oversubscribed.

Sky: Avoid, many dropouts, bills doubling in price for no reason

TalkTalk:  From one of my neighbor's experiences 10 years ago I would say no, but maybe things have changed since.

Take a pinch of salt with any reviews site:

Doctor Who Adventure Games

If you have a copy of the original installers for the Doctor Who Adventure Games (contact me on the form at the bottom of the page if you want them), you'll find out that they will fail to run with an error message, because they are validating them against the Doctor Who BBC website, and they were taken down due to a licensing issue with the developer.

However, it's not too hard to remove the validation on the underlying installer's code so that you can always run them.

Some things to be aware of:

A. The installers are partially cumulative updates on top of one another - meaning that by the fourth episode, a lot of the code in the previous versions was updated. The installer automatically replaces any old files based on their date - whatever is older automatically gets replaced with the latest version. The order is as follows:

1. City of the Daleks

2. Blood of the Cybermen


4. Shadows of the Vashta Nerada

5. The Gunpowder Plot (has its own launcher so can be done separately)

B. The Steam versions appear to put a valid keyfile.txt in the installer so that the games can be run and skip the validation entirely. It might be unique to each person's copy. I've not tried running it without Steam installed. Some other code was updated in the Steam version to add achievements, alongside general map and audio updates, so you won't want any of the achievement code if you're using these versions.

Here's a summary of the changes made:

1. Extract the EXE file with an InnoSetup extractor such as UniExtract

2. Using Resource Hacker, or a hex editor, you'll need to edit the file DoctorWho_Pc.exe as per the following screenshot. By changing the JNZ (Jump if not zero) to a JMP (always jump) - explained here, you can skip over the code that performs the validation. Here I am editing version 4.0 of the file which was in the fourth episode, Shadows of the Vashta Nerada. You can use this version with the three others without issue.

3. You need to create the file keyfile.txt inside the {app} folder, and it's just an empty file.

4. You need to edit the install_script.iss to not copy the InstallValidator.exe file, and instead copy the keyfile.txt

5. So to summarise the changes needed. The Output exe is created in the next step.

6. Next, you need to use Inno Setup Compiler to open the install_script.iss and compile the binary (Build > Compile). The output is the .exe file as above.

7. Rinse and repeat for all 5 of the installers. I'd recommend replacing the file DoctorWho_Pc.exe in each of the installers you recompile so that all of them can be installed. Note that The Gunpowder Plot uses a different EXE entirely so the hex edit will have to be reproduced for just that one.

Keeping your home network secure

  1. Privacy
    1. Use a VPN that isn't part of 5/9/14 eyes, has unlimited data, doesn't log you https://www.vpn.com/guide/spreadsheet/
    2. Reduce Microsoft telemetry with O&O ShutUp - and why
    3. Pi-hole
  2. Updates
    1. OS
    2. Apps, firmware, drivers
  3. Credentials
    1. Passphrases instead of passwords, or random passwords and a password manager
    2. Unique passwords for everything - haveibeenpwned.com
    3. Enable 2FA on all accounts
    4. Change default passwords on all IoT devices including the router
  4. Router
    1. Move to WPA3 and change and hide your SSID so your model of router isn't publically available and it can't be tracked to your name. Disable older methods (be exclusive, not inclusive)
    2. Disable WPS, UPnP, remote management, port sharing, update the router or move to one with granular control like creating a second network for IoT devices
    3. Disable DHCP and use static addresses and known MACs, and change the IP range from 192.168.xxx.xxx
    4. If feasible, turn off the just the WiFi when you're not in so there is less chance of attack. Keep anything critical on LAN connections.
    5. When travelling, take a travel router with you, and/or use an SSH tunnel to your home address (the Firewalla has the option of a VPN server)
  5. Services
    1. Disable remote access
    2. Disable Samba v1
    3. Secure DNS
    4. Disable bluetooth and any listening devices e.g. Google Home, Amazon Alexa, Apple Siri
    5. Port scanner e.g. nmap (use internally and externally) - prefer instead of website port scanners
  6. Internet
    1. Use an internet security product rather than just antivirus (e.g. sandboxed browsers for banking, phishing filter, granular control of incoming and outgoing apps)
      1. https://rjcuk.blogspot.com/2021/05/antivirus-internet-security-products.html
    2. Use more than one AV product or set of tools
    3. On any downloads, check SHAs where possible and use VirusTotal, enable SmartScreen, run apps in sandboxes where preferable
    4. Setup a honeypot
    5. Network/IP/LAN monitors and scans including scanning from the internet for open ports
  7. Isolation
    1. Use VMs, containers or sandboxes (Windows 10 has one now)
    2. Wipe and reinstall your machine regularly
      1. Attendees of Black Hat conferences go as far as to dump their laptops afterwards
      2. If you're going to the US, use burner equipment - why
      3. Elliot in Mr Robot uses the microwave, but I don't recommend it - more advice
    3. Encrypt your HDD/SSD
    4. Route all traffic through a local gateway/proxy e.g. Raspberry Pi
      1. Squid proxy for just HTTP/S
    5. Firewall e.g. Firewalla
    6. Use a guest network for IoT devices and friends
  8. Physical security
    1. Turn things off when not at home
    2. Don't leave any devices "on display" - lock them away when not using them
    3. Scheduled offsite backups - encrypt the data itself (some tools can provide this) e.g. cloud
    4. Cameras e.g. Ring. Either keep wireless ones on a separate guest network, or get wired ones instead.
      1. You could use Powerline but it doesn't work for everyone and your electrical grid may be shared with your neighbours.
  9. Use Linux
  10. Other general advice
    1. Online safety
    2. Cyber aware
  11. Security hardware
    1. linitx.com
    2. ebuyer.com
    3. novatech.com

Ethics and suggestions for government

Things I consider unethical (actively bad for the majority of people)
  • Credit cards
  • Stocks and shares
  • Driving diesel/petrol
  • Smoking (especially in public)
  • Excessive drinking
  • Excessive ownership of money (large spending should be regulated, advised and approved)
  • Excessive gambling (more than your excess income)
  • Cruelty to others, animals (i.e. physical abuse, domestic violence) and abandonment
  • Funding anti-LGBT business (or any anti-equality-based division)
  • Public possession of guns

Things that I think may be controversial, but are the right way forward
  • Pornography
  • Eating meat irregularly, sustainably or being vegetarian/vegan
  • Opting for renewable energy resources
  • Adoption (submission and selection)
  • Euthanasia

Improvement required:
Things that the government really needs to work on
  • Universal basic income
  • Mental health walk in centres
  • Online systems for voting and more regular votes
  • Learning and education past 18 for changes to UK law or curriculum, to cover finance, jobs, looking after yourself, cleaning, DIY etc
  • Self assessment tax returns - should be much more automated
  • Tax rebates - Should never be so problematic
  • Prohibition of drugs
  • Driving licences should require regular reassessment of updated practices
