The computer virus is a malware that reaches your machine via the Internet without your knowledge. Software viruses are of different types and pose different levels of threat. Depending on the form, you can change your computer settings and sometimes even destroy your hard drive and cause data loss. There are hundreds of antivirus applications that can delete malware from your computer. However if you do not want to download external software and want to uninstall viruses manually, you can opt to restore your computer to a previous date before your system files and registries have been corrupted.
