Notes

Some companies — notably Microsoft — publish much more information about problems. This is not because their products are more prone to problems: it is because these companies make more products, or make a stronger effort to fix problems and inform customers.

Some companies don't release security fixes for old but widely used products: e.g. Microsoft doesn't support any version of Windows older than Windows 7. Users are advised to upgrade to newer products, but many new products can't run on old PCs: such PCs will become increasingly vulnerable as time goes on.

For virus news see the Symantec Security Response Center.

Here are recent security fixes and tools to deal with security fixes:
