What to Do When Your Computer System Gets A Virus

A single click on an infected link or an attachment is all it takes for your computer to get a virus. This can slow down your CPU, harm your stored data, and spread among your email contacts through the internet.

Antivirus software and firewalls can be of use only if they are regularly updated. If you have turned off the automatic updates, or if the virus is a very new one, here are a few steps that can minimise the harm:

  • Download the latest antivirus updates and run a full system scan. If a virus is detected, follow the instructions given by the antivirus software.
  • You can also run the scan in Safe Mode if you cannot boot into Windows.
  • If a virus is not detected in the scan, it might be a new virus, the scan might not be running properly, or it might be a different technical problem. In that case, it is best to call in professional computer technicians – like the ComputerZen team.

Taking precautions

Meanwhile, there are certain precautions that you can take to prevent spread of the virus and to keep your information as safe as possible:

  • Disconnect from your WiFi network to prevent your other devices from getting infected. You are essentially putting your computer in quarantine, just like what you do when you catch a contagious virus.
  • Don’t do any online banking or shopping and avoid typing in sensitive information like passwords even from other devices until the virus has been removed.
  • Do not send any emails that contain attachments to anyone to avoid spreading the virus.

Preventing further attacks

computer-virusOnce our ComputerZen technicians have removed the virus, it is a good idea to change all relevant passwords, in case they have been stolen. This includes not only your email and ISP passwords, but also the passwords of all sites that you use regularly.

It is also important to learn from your experience and keep your antivirus software and security patches updated regularly. Similarly, make it a practice to create back-ups of your important data on external hard drives or CDs.

Following safe browsing practices – like not clicking on questionable links, not downloading unknown attachments and double-checking before installing new software from unfamiliar sites – is your best defence against viruses and other malware.

Software Virus Ransomware Holds Your Computer Systems Hostage Unless You Pay

Transcription

NEWSREADER
Thousands are falling victim to a sinister new computer crime – Ransomware freezes your computer and holds it hostage until you pay.

REPORTER SHANE DOHERTY
It’s one of those web sites that let’s you watch TV and the latest movies for free.

TOBY HAZLETT, COMPUTER ZEN
Yeah, it looks quite innocent and quite fun – make the monkey happy.

REPORTER SHANE DOHERTY
But if you, your staff or your kids have used it, it could be too late.  Click on that and you’re a goner?

TOBY HAZLETT, COMPUTER ZEN
Basically, yeah.

BRENTON DEANE, VICTIM
We were absolutely, totally disabled, we just couldn’t do anything.

REPORTER SHANE DOHERTY
Brenton Deane is just one of the victims of Ransomware, a sinister new tool of the cyber criminals.  They even wiped his back-up material and brought his bus company to a standstill.

BRENTON DEANE, VICTIM
We couldn’t invoice anyone.  We couldn’t pay anyone.

REPORTER SHANE DOHERTY
The program gets in when you open a suspect email or visit one of those sites.  Crooks have used it to operate webcams in people’s bedrooms then threatened to upload the images to YouTube.  They’ve stolen photo albums and home movies, even frozen inappropriate images on screens until you pay.

This one tells the computer owner they’ll dob them in to the Federal Police for illegal downloads or looking at pornography unless they pay the extortion.

TOBY HAZLETT, COMPUTER ZEN
In the end, you know, he was stuck and he had to pay.

REPORTER SHANE DOHERTY
After a few days of trying everything else, that’s exactly what Brenton did.  $3,000 bought his company back online.

BRENTON DEANE, VICTIM
It’s probably not the right thing to do to pay the ransom, but it’s worth a try or else we could be stuck for weeks.

REPORTER SHANE DOHERTY
The advice: make sure your computer’s protected with the latest anti-virus software and keep a hard drive back-up separate from your computer.

TOBY HAZLETT, COMPUTER ZEN
They’ll do anything to get in there and, yeah, you just have to be safe and aware.
