Anti-virus software

Anti-virus software helps to protect against viruses and other types of malware, such as ransomware and spyware. Malware can have very serious consequences, such as:

  • Identity theft and fraud
  • Deletion, theft and corruption of data
  • A slow or unusable computer

Keeping your anti-virus software up to date is essential. Thousands of new viruses are detected every day, with lots of variants of new and existing ones emerging. Most antivirus software update automatically to provide protection against the latest threats.

Antivirus software detects and removes, or disables, malicious programmes. It does this by:

  • Scanning email attachments as they arrive in your inbox
  • Checking files as you open them to make sure they are not infected
  • Performing regular scans of the files on your computer

Some anti-virus programmes have additional features, such as scanning USB devices when they are connected, or highlighting suspicious websites.

 

Top Tips for anti-virus software

  • Anti-virus software for home use can be downloaded from Pegasus 
  • Uninstall one antivirus program before you install another

While it will not provide 100% protection against all cyber threats, antivirus software is an essential first line of defence. Other steps you can take to avoid malware include:

  • Backup your data regularly
  • Do not open email attachments unless you are sure the email is from a trusted source
  • Be aware of malicious links in emails, instant messages, social networking sites or other websites
  • Use USB connected devices with caution (e.g. memory sticks, external hard drives, MP3 players) as they can be used to carry malware
  • Enable macro protection in Microsoft Word and Excel
  • Only install software from reputable sources
