Updates are especially important for anti-virus programs because without updates these programs will not protect your computer from the newest viruses.

True

Explanation:

The importance of updating our software / programs is not only delegated to the Antivirus but it is a routine that we should incorporate into any program installed on the computer whose function is security.

In the particular case of Antivirus, the update is necessary due to the simple fact that one of the tools that it has to prevent or detect the entry of computer viruses in time is the detection through its database.

   Basically, what it does is take a code snippet of the virus in question and incorporate it into its database, so that later, either through scanning or permanent protection, when a new file is entered or processed on the computer This will compare that piece of code available in the antivirus database with the file that is being used, and in case they match, an alert will immediately appear in our system notifying us that a virus has been found.

The efficiency of this process is closely linked to the "quality" of the database, let's say, the more records this has, the wider the spectrum covered by our Antivirus will be.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
