Can be damage by a virus?
Your programs may not work and you may not be able to enter
certain folders. But this is not the reson for a virus, any
personal recourds on your computer will be shared to the person who
made the virus. This includes contact, passwords to websites, bank
account information, and anything else. There are some viruses that
can travel to other computers just by being in the same wifi as the
computer with the virus! To prevent virus get virus protection
which can be found free at cnet.com (type in advast in the search
bar when you are in the website) but still be careful because you
can still get viruses even when you have virus protection
software.
