How do you get a virus on your USB stick in a wanting way?
Transfer the executable file hosting the virus from the PC to the flash drive.
It is possible for an Apple Macintosh to get a virus, so the short answer to the question is Yes. However, the likelihood of an Apple Macintosh user getting a virus when compared to a Microsoft Windows user is very little to none. In fact, many of the Apple Macintosh users don't even run an antivirus protection program.
Below are some of the reasons why Apple Macintosh computers do not have as many viruses as Microsoft Windows.
- Newer Macintosh operating systems, such as the Mac OS X, is built on the Unix kernel, which is one of the oldest and most secure operating systems available.
- Microsoft Windows is used by a lot more users. Because more users use Microsoft Windows, it is a lot better of a target than Apple Macintosh computers.
- Most of the virus writers are familiar with the IBM platform and Microsoft Windows, and therefore are only going to be able to create a virus for that platform.
- Many of the tools and scripts used to help users create viruses or other malware are designed for Microsoft Windows.
A listing of virus protection programs as well as virus protection programs that support the Apple Macintosh computer can be found on document CH000514.
Note: If you're running a virtual PC on your Apple Macintosh, because it's emulating Microsoft Windows, it can become infected with Windows viruses and you should be running an antivirus protection program on it. In addition an Apple Macintosh can serve as a virus carrier, meaning that a virus could be stored on an Apple Computer but not infect it. If that infected Macintosh were then to connect to a network or forward an infected e-mail to a Windows computer it could become infected.
Additional security threats
Although a Macintosh computer is less susceptible to viruses because it is a human who's operating the computer you still can be a victim of Trojan horses, phishing, and other online fraud. If you're a Macintosh user we still recommend keeping informed about how to keep safe while online. See document CH000507 for additional information about keeping safe online.
Why am I getting a pop up during start up saying spyware is detected?
== == You have a problem. In my experience I have come to notice similarities between programs. One of those is that a malware detection just doesn't show up out of the blue if it is legitimate. So you have either adware or spyware in your system. So I am going to give you a link that will allow you to download very useful software called Windows live onecare. The link is http://onecare.live.com/standard/en-us/3/communications/trytoday.htm You need to run these 5 essential steps to remove all the spyware on your computer.

Install threat fire which will enhance your antivirus protection Depends on where the waring message is coming from. If the pop-up is coming from your AntiSpyware software that you have installed on your computer, then just run your program and let it remove anything it finds. If however, it is a pop-up not associated with your program, you have spy-ware installed on your system. Disconnect from the INTERNET and run your AntiSpyware program to remove it. If you do not have antiSpyware software installed, then I suggest you download Adaware SE and run it. Go to www.download.com and get Adaware SE. Other good free ones are Microsoft Antispyware and Spybot Search & Destroy.

Whenever i enter a disk into my computer it causes it to reboot why is this happening?
If you see a blue screen before this happens then either there is a problem with the Disc Drives, I/O and your Operating system doesn't agree, or the disk you are using is causing a problem with the operating system.
It may also be a power supply problem as the drive may be trying to use power but may not have enough and by default the motherboard will shutdown the computer in an attempt to save itself from a shortage of overload.
Other than these above I cannot give you anymore without being there or having more detailed information.

Well, it looks like your computer is infeccted by some sort of virus, as well as a Trojan which probably carried the software to send fake messages about a spyware infection, probably courtesy of AntiSpyware Master.

What is the average size of email?
E-mails in general do not have a set size. Because of the numerous factors involved it is hard to pinpoint an e-mails 'average' size. For example, it depends on the the number of images sent, are there any attachments(?), how long is the e-mail and so on. However, a medium 80 word e-mail could range from an average of 7kb to 11kb. Some applications such as e-mailers on phones may have smaller sized e-mails ranging between 2kb and 6kb. Once again, this is using text only and not alot of it. This is a difficult question but I hope I helped. =)
How do you fix a parameter that is out of range on my computer?
It depends if this is when you first turn on your PC or in an application. If its when you first boot your PC, you could have corrupt system files, a file system error, or a failing hard drive. At any rate, you should back up your data as soon as possible.
To rule out the hard drive as a problem, find out which manufacturer's drive is installed and get their testing utility. It would be best to have the version the burns to a CD, and then boot up off of that CD. That way, even if you cannot get into Windows, you can still test the drive. If it finds bad spots, you should let the software relocate the data to spare sectors. That should make things more stable, at least long enough to do backups.
