viruses could cause be the cause of a slow computer; im not 100% sure.
Improved:
While this is true it could also be from the computer having too many applications running at the same time, or from a lack of resources such as RAM and Hard Drive space. plus if you open too many processes at a time it would also affect your pc speed.
No It Does Not.
Kinda but it depends on your computer if you have to many programs it will go slower but if you have few it will be pretty normal speed
Depending on what your PSU wattage is, otherwise no.
The virus can make a computer run slower than usual, or stop the computer from working.
i don't use it because it will make my computer slower
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.
No If the computer runs faster then it runs faster not slower
It's not!
Depends. Some "pop-ups" are actually malware or adware.
It depends on your computer and your internet. The worse internet the slower the worse computer and more slower.
no. playing games will not make your comp slow. If you download a game that takes up alot of member then, probably your computer would get a little slower.
no not at all infact it makes it faster if u get the toolbat
