Why the DES is slower in software?

I can only guess that you ask about the performance of the DES algorithm when implemented in software as opposed to hardware. Any algorithm that can be economically implemented in hardware will perform faster in hardware than software by orders of magnitude in the general case. Encryption algorithms such as DES are often based on a shift-combine-shift sequence, which is fairly easy to implement in hardware, but can take considerable processing time when implemented in software.

Why did the computer get slower after the antivirus?

Anti-virus software are programs that run on your computer. At any one time there are lots of programs running on your computer. The more that are running, the slower the computer can work. So when you install a new program like anti-virus software, it is an extra program to run which will make your computer slower. It is still important that you do use anti-virus software, even if it does slow down your computer.

Why does Windows slowdown after installing more software?

It might not necessarily be that Windows itself is slowing down. A more likely cause is that the computer which now has more software on its hardware, takes a longer time to process everything, making Windows seem slower.

If you have 2 computers connected to the same router then why is the second computers download speed slower?

It's difficult to say from here without more information, but the things I'd look at are:Are the two machines the same - does the slower machine have less memory, slower hard drive, slower processor or different software? Are the files being transferred to the main drive of the computer - for example, FAT is much slower than NTFS so if download to a FAT formatted memory stick, it will be a lot slower. Are both PCs connected in the same way? (if one is wireless connected and the other using a cable, the wireless will be a lot slower).Are there any errors being reported for the Ethernet connection on the PC?
