These are just some of the signs of the spread of virus:
• A slower computer
• A computer that starts to freeze
• A computer that restarts on its own
• Files and applications that cannot be opened
• Files that have disappeared as if by magic
• Sudden decrease in memory
There are different types of computer viruses. These are the boot virus, the resident virus, the infecting files virus, the virus that comes from emails and email attachments, and the overwrite virus which turns files into garbled text.

Let’s say you already know how an antivirus works, the next step will be to install one on your PC. You can start by getting desktop security software guide online to help you in choosing the best antivirus software. With an antivirus software you have the comfort of knowing that these files will have difficult time sneaking into your computer, and if they manage to do so, will have an even more difficult time staying hidden. A good antivirus software will be able to completely scan your computer and find these malicious files, delete or quarantine them so they do not cause any more harm.
