Antivirus Tip: NEVER click on e-mail attachments or links provided without verifying if the sender and/or the contents are safe and scanned.

Antivirus Tip: No single anti-virus program can provide 100 per cent protection. Using two or three programs to provide a wide security net is preferable.

Antivirus Tip: Depending on the web browser you use, installing an appropriate ad-blocker and other safety add-ons can be helpful.

Antivirus Tip: Installing dedicated anti-virus or malware software can be a second line of defence, on top of practising vigilant internet browsing.

Antivirus Tip: Disable the autorun function on all USB ports, as most malicious software automatically installs itself when autorun activates.

Antivirus Tip: Ransomware, which is malware locking you out of your PC unless a ransom is paid, is becoming more frequent. Educate yourself on these threats.

Antivirus Tip: Free anti-spyware software often do not provide an adequate level of protection, so consider investing in a paid professional package.

Antivirus Tip: Make sure your anti-spyware has ‘link protection’ which scans a page against a database of updated addresses that are known to be harmful.

Antivirus Tip: Use multiple programs, anti-virus and anti-spyware, to provide adequate protection from spy- and malware, especially when browsing the internet.

Antivirus Tip: Check your browser settings to see what plug-ins are installed and verify what you have, or you might install malware that installs more viruses.
