to collect up-to-date information on the latest threats from all participants worldwide,
and in return we can improve protection for everyone.
The reporting is taken care of automatically, therefore does not cause you any
inconvenience, and no personal data is included in the reports.
Reporting of
detected threats is optional, however, we do ask you to keep this feature on, too, as
it helps us improve protection for both you and other AVG users.
Nowadays, there are far more threats out there than plain viruses. Authors of
malicious codes and dangerous websites are very innovative, and new kinds of threats
emerge quite often, the vast majority of which are on the Internet. Here are some of
the most common:
·
A virus
is a malicious code that copies and spreads itself, often unnoticed until
the damage is done. Some viruses are a serious threat, deleting or deliberately
changing files on their way, while some viruses can do something seemingly
harmless, like playing a piece of music. However, all viruses are dangerous due
to the basic ability of multiplying – even a simple virus can take up all the
computer memory in an instant, and cause a breakdown.
·
A worm
is a subcategory of virus which, unlike a normal virus, does not need
a "carrier" object to attach to; it sends itself to other computers self-
contained, usually via e-mail, and as a result often overloads e-mail servers
and network systems.
