Computers can develop rebooting problems, resulting in the inability to access data. Sudden voltage changes can damage computer hardware and lead to data loss.

Restore points from previous days should work, provided the virus is not designed to corrupt the restore files and does not exist in previous restore points. Software development strategies that produce large numbers of “bugs” will generally also produce potential exploitable “holes” or “entrances” for the virus. Most modern antivirus programs try to find virus-patterns inside ordinary programs by scanning them for so-called virus signatures. Different antivirus programs will employ different search methods when identifying viruses.

As a result, I’ve seen many cases where firewalls have simply been disabled altogether. Users should never click on email attachments without at least first scanning them for viruses using a business-class anti-malware application.
