Security updates

In very rare instances, new types of viruses are released that attack ports in your firewall that might not be protected. Therefore you need to manually update your antivirus software against this type of attack. Your own software is your last line of defence.

Failure to update systems helps worms spread
The most common and widespread worms and viruses typically exploit new ways to access PCs, but once inside they use old and well-known security holes in the programs on the PC to reach their target positions. These worms are allowed to proliferate because many people fail to update the operating system and programs on their PCs, even though the software providers have long identified and remedied the problem and made updates available on the Internet.

Update frequently or automatically
We recommend that you look at the Web sites of your software providers at frequent intervals and update your software when security upgrades are available. The more recent operating systems allow users to select automatic installation of updates, which is usually recommended.
