Different types of problems caused by viruses and iYogi’s expert guidances to fix and prevent suhc problems.
A virus is a malicious program that has been designed specifically to cause harm to the computer. PCs and laptops can be infected in many different ways i.e. file downloads, sharing of storage media and e-mail attachments. The result if computer virus infection can be quite harmful and damaging to your PC or Laptop. In addition they increase the risk of hacking threats and attacks.
The various symptoms displayed pursuant to virus infections are discussed in the following points.
- Reduced memory space
- Boot failure
- Undesired operations
- File deletion
- Guarding against viruses
Reduced memory space
The computer hard disk and other storage devices memory will be eaten up as a result of work infection. They cause files and folders to replicate themselves in the media causing usage of the available spaces. This in turn causes the performance of the PC to be affected by becoming unusually slow due to less available working space left.
The computer fails to boot up. This results from the boot sector of the hard disk being infected in such a way that the critical system files needed to run the system are deleted. The boot sector may also be hidden by the virus such as to make the operating system not identify where to boot from at startup.
Some viruses may not be harmful to the system but cause undesirable operations that cause the user to be constantly interrupted. These may be uncontrolled movement of the cursor, wrong keystrokes and pop-up screens appearing all the time while surfing the web. In addition the hardware may be affected i.e. DVD-ROMs may keep opening and closing on their own.
User files and applications are deleted causing either the applications not to be launched or derail the user activity in the computer. These are malicious virus types as they directly harm the user and the system as a whole.
In addition with modifications some virus types have managed to alter some critical Windows files such as not to access anti-virus sites. This is primarily to prevent the user from downloading updates and virus removal tools.
