'Ghosting' is a process in which hard drives on networked computers are wiped clean and then original software is re-installed. This process is an effort to prevent viruses and malware from doing damage to computers on the network. Outuit Company performs ghosting on its computers every week. Thus, any virus-related damage that occurs to an Outuit computer is the result of a recent infection that occurred within the last week.

Which of the following, if true, most seriously weakens the conclusion above?

1. Damage to computers by viruses closely resembles damage caused by worms, another type of malicious computer program.
2. Outuit has one of the most sophisticated computer security systems in the country.
3. In some cases, viruses have been known to reside in the BIOS of a computer, a section of memory that is independent of hard disk space.
4. In addition to ghosting, the computers on Outuit's network have anti-virus software that actively scans for viruses.
5. Most computer viruses, once installed, usually do damage to the infected computer in less than a week.

The argument assumes that hard drive is the only part that is vulnerable to virus attack and goes on to make a wild conclusion that the virus attack must have happened within the last week. The author makes this conclusion because he is under the impression that any virus in the hard drive will be wiped out every 7 days and as per the author hard drive is the only part that is vulnerable to virus attack. In order to weaken the conclusion we must attack this line of reasoning. 'C' is the correct answer as it states that virus can attack other parts as well so this attack could have any time in the past and ghosting which just checks the hard drive would not have spotted this virus.

Need to weaken the conclusion that virus-related damage happened within last week. So, option 3 is correct as it suggests sometimes virus stays in BIOS and is not cleaned up by Ghosting.

Which of the following, if true, most seriously weakens the conclusion above?

3. In some cases, viruses have been known to reside in the BIOS of a computer, a section of memory that is independent of hard disk space.

I'm not an expert but even then i think i can help you to understand why option D is incorrect. Option D says talks about techniques apart from the Ghosting that isn't part of the argument. So always remember to mind the gap in these question types. If you carefully observe the premise is talking about the Ghosting process for the Hard disk but the conclusion is about the virus not found in the complete system.
Hope this helps.
