I oftenly saw that notifications on my old desk top that said, your computer is running slowly it seems to be infected with some computer viruses. So l really wonder what might be the cause of the computer viruses?

Visiting unprotected sites and downloading corrupted files can be a major cause of getting your computer corrupted with virus.

Computer viruses enter in many ways. They often come from downloading programs from unsafe websites or opening untrusted email attachments. Also, infected USBs and not using antivirus increase the risk. A system without security updates is easily affected. Avoiding viruses is easy by using the right antivirus and avoiding dangerous websites.

After reading this, I am feeling outstanding level of relax as finally I passed that era and using my mobile phone with all pc functions without facing that virus problem. When I was using my PC this was biggest problem as my PC was infected by virus and I used to go to nearby repair shop where the cheater man had one same story as your hard disk is effected and you must pay this big amount to install new one.
