- Almost all virus's affect your computer hardware.... Most will affect the network card and processor since they are adding a load to the devices without your consent.... Some may affect your keyboard.... Such as Macro.... Some go after your printers....
- This type of virus infects Master Boot Record (MBR) or DOS Boot Record (DBR) of a hard drive and Floppy Boot Recorde (FBR). MBR is the first sector of a hard drive and is usually located on track 0. It contains the initial loader and information about partition tables on a hard disk. DBR is usually located a few sectors (62 sectors after on a hard disk with 63 sectors per track) after MBR. The DBR contains the initial loader for an operating system and logical drive information. The FBR is use for the same purposes as DBR on a hard drive, but it is located on the first track of a diskette. A boot virus can be overwriting and relocating. An overwriting boot virus overwrites MBR, DBR or FBR sector with its code preserving patrition table information or logical drive information respectively. Relocating boot viruses save the original MBR, DBR or FBR somewhere on a hard or floppy drive. Sometimes such action can destroy certain areas of a hard or floppy drive and make a disk unreadable. All boot viruses are memory-resident. When a computer is started, boot virus code is loaded in memory. A virus traps one of BIOS functions (usually disk interrupt vector Int 13h) and stays resident in memory. A virus then monitors disk access and writes its code to boot sectors of media that is used on an infected computers. For example a boot virus started from a diskette infects a hard drive. Then a virus will infect all diskettes that are inserted in to infected computer's floppy drive. Boot viruses are quite rate nowdays, besides most of computer motherboards have protection against boot viruses - access to MBR is denied without user permission.
- No virus (software) can affect or damage hardware. It will only screw up the functioning of the hardware when the functioning is driven by the software part of the hardware. All these scenario easily make people think that the hardware is screwed up by the virus. Actually the root problem is the software part which drives the hardware is screwed up by the virus, such as MBR or FAT of the HD, system BIOS, and even the OS of your cellphone, or palm, etc. if they are infected by virus.
- All have some effects...! I can give a few links that offer free virus and spyware removers...!You may be having a virus or spyware installed on your PC. Norton, AVG , Avast are free antivirus software. Ad-aware, Ewido are free spyware removers. You can download free softwares at http://fixit.in/antivirus.html and http://fixit.in/spywareremover.html
