Everybody is always scared of getting a virus on their computer. A virus, essentially, is an infection that affects any or all parts of the computer. It can be reasonably benign, in as such that it only forces advertisements on you (adWare), or it can be malicious to try and steal your information (SpyWare). It is even possible for it to create a network in order to attack other computers.More over you can also get your deleted files form this software recover deleted files

- Worms, which self-replicate and spread to other computers and files in order to create damage.
- Rootkit viruses, which covers your computer’s Registry, hiding what another virus is doing.
- Boot-sector viruses, which don’t really exist anymore, as they were usually found on old fashioned floppy disks.
- Logic bombs, which are designed to overwhelm systems.
- Memory resident viruses, which h ides in your RAM to interrupt certain operations.
- Multipartite viruses, which spread in a range of different ways at the same time.

- .exe files with existing folder names appearing.
- Your internet security software telling you that you have a virus.

What You Can Do
If you suspect you have a virus:
- Install or update an antivirus program.
