Can a power supply get a virus?
Power Virus Origins Power viruses are contracted the same way as other viruses. They’re passed along — often by your system’s electrical neighbors. Plug your system into the wall, turn it on, and look out. You’ve just been exposed to an epidemic, and there are a lot of very sick electrons looking to cause problems.
What are the three types of computer viruses?
The three types of computer viruses
- Macro viruses – The largest of the three virus types, macro viruses use built-in programming scripts that are found in Excel or Word to automate tasks.
- Boot record infectors – Boot viruses, or system viruses, attack programs found on floppy and hard disks.
How does a computer virus attack?
A virus operates by inserting or attaching itself to a legitimate program or document that supports macros in order to execute its code. In the process, a virus has the potential to cause unexpected or damaging effects, such as harming the system software by corrupting or destroying data.
Can BIOS be hacked?
A vulnerability has been detected in the BIOS chips found in millions of computers which could leave users open to hacking. BIOS chips are used to boot a computer and load the operating system, but the malware would remain even if the operating system was removed and re-installed.
What part of a computer gets a virus?
Viruses can be spread several ways, including via networks, discs, email attachments or external storage devices like USB sticks. Since connections between devices were once far more limited than today, early computer viruses were commonly spread through infected floppy disks.

What is the function of the power supply in a computer?
It receives power from an electrical outlet and converts the current from AC (alternating current) to DC (direct current), which is what the computer requires. It also regulates the voltage to an adequate amount, which allows the computer to run smoothly without overheating.
Should I remove the power supply from my computer case?
Of course, you should never have to remove the power supply, so it’s best to leave it in the case. While most computers have internal power supplies, many electronic devices use external ones. For example, some monitors and external hard drives have power supplies that reside outside the main unit.
How do I protect my power supply from voltage drops?
You can protect your power supply and your computer from surges and voltage drops by investing in a UPS (uninterruptible power supply). If you cannot afford a UPS, make sure the computer is at least plugged into a surge protector. Where is the power supply located in a computer?
What is a computer virus and how does it work?
A computer virus is a type of malware that, when executed, replicates itself by modifying other computer programs and inserting its own code. When this replication succeeds, the affected areas are then said to be “infected” with a computer virus. Virus writers use social engineering deceptions and exploit detailed…
