Anti virus

Anti-virus and anti-malware software helps to protect your computer from viruses, worms and other malicious software. However the protection is only as good as the last update, as new viruses and malware are released every day.

  • Use one anti-virus product (more than one may conflict with each other)      
  • There are a number of free products for non-commercial use, these include:
  • But do a search/check computer reviews and use products from a reputable vendor or provider, ensuring you comply with all licensing requirements.  
  • Schedule daily updates for when the machine is switched on and online.
  • Schedule a weekly full system scan to check for infected or corrupted files.
  • Windows users might also like to consider additional anti malware protection, such as Malwarebytes, Spyware Blaster or Spybot.

Common symptoms of a virus infection:

  • Virus program alerts;
  • Pop-up advertising;
  • Access to files denied;
  • PC will not start;
  • PC is unusually slow;
  • PC restarts without your authorisation;
  • Files have disappeared.

How to recover from a virus infection

Check that your virus definitions are up to date (View the program's Help - About screen to check for the last update). If more than two days, manually apply an update from the anti-virus provider's site, then disconnect from the internet before:

  • Running a complete scan;  
  • Cleaning/disinfecting any viruses found.

Also scan and disinfect any external drives e.g. USB memory sticks and disks, otherwise you will keep re-infecting your computer.

If symptoms persist, start the machine in Safe Mode. To do this press F8 during start-up (before the Windows Start-up Menu is displayed) and then select Safe Mode. This means the PC will start-up in a minimal configuration, with only essential parts of Windows loaded. Then repeat the above actions—run  the  complete  scan etc. If symptoms still persist, the only remaining option is to reinstall Windows using the original disks.

I use a Mac and they can't get virus infections

Wrong! This is a commonly held belief. Although Windows based machines are more prone to infection (due to high numbers of Windows users worldwide) Macs can still get virus infected. It is less common for a Mac or Linux run computer to have a virus infection, but virus writers are widening their scope  and  targeting  anything connected to the internet. Anti-virus products are available for these machines, so get searching and apply the same protection principles as advised for Windows users.
