1) The major disadvantage to backing up your data on CDs or DVDs is that they are _____
a) not writable b) slow c) volatile
2) A virus that infects an application program is known as a _____.
a)a boot sector virus b) Trojan horse c) file virus.
On #!, I don't think that CDs and DVDs are volatile since they are permanent - unlike a program or Word file. but I didn't think that they were particularly slow - but I guess they would be slower than, say a flash drive? As far as writable, aren't there writable CDs and DVDs? So is the answer b) slow?
On #2, I know that a file virus can affect applications such as Word and Excel. A boot sector virus affects the boot sector of the start up drive, but I also read that it can affect pirating applications. Also from what I read, it would seem that a Trojan Horse could affect application programs as well, although not as readily. Now I'm really confused. Any help is greatly appreciated. :-)

Mcafee will not let you install eonythar program but Window Defender. Try that one and it will let you get rid of any spyware or allow you to turn off the trojan program. I would also try to boot in safe mode and do a scan for Spyware with McAfee Oh yes You can reinstall but usally take longer than just doing the scans ..If it just got the Trojan recently you can restore your computer to a early time .
