Microsoft to Offer Free Virus Protection Software for
Windows
By Scott Gilbertson November 19, 2008
Microsoft plans to offer Windows users a new antivirus
package designed to protect the OS from viruses, spyware,
rootkits and trojans. The new software is tentatively code-
named Morro, and will be available for free to Windows XP,
Vista and 7 users sometime in the second half of 2009.
The new software will reportedly use very minimal resources,
which means it should work well with older PCs. If fact,
Microsoft says Morro has been specially designed for older
PCs and low-spec machines popular in developing nations. In
addition to its minimal processor demands, Morro has been
developed to use very little bandwidth,making it ideal for those
without broadband connections.
Morro will replace Microsoft’s current, paid service, Windows
Live One Care, which has been available on a subscription
basis for $50 per year.
While a free, antivirus solution that ships with Windows would
be a boon for the average user, it could also mean trouble for
third-party software solutions. Given that a bundled solution
could raise antitrust concerns and would no doubt see
competitors like McAfee and Grisoft reaching for the lawyers
Microsoft will be offering Morro as a separate download.
Assuming Morro can deliver decent security it should be a
welcome free addition to Windows, but we don’t suggest
throwing away your third-party software just yet. Antivirus
software suites will likely continue to hold an edge over Morro
by offering additional handy tools like password managers,
identity theft protection and browser-based phishing
protection.
Still, if you’ve been running Windows with no antivirus software
at all,Morrowill no doubt be better than nothing, and it’s hard to
argue with free.

- A)should / in / haven't been;
- B)must / on /won't be;

- E)Should / on /were not.
Resposta:
A alternativa correta é C)
O gabarito correto é a alternativa C) should / on / haven't been.
A frase completa seria: "You should not believe that these possibilities are real, they're based on experiments that haven't been proved until now."
Should é o modal verb apropriado para expressar conselho ou recomendação, indicando que não é aconselhável acreditar nessas possibilidades. A preposição correta após "based" é on (baseado em). Por fim, haven't been é a forma correta do present perfect na voz passiva, indicando que os experimentos não foram comprovados até o momento presente.
