What Kind of Damage Can A Virus Cause?
A virus can damage your PC in a number of different ways. At best it can take up memory space and affect the performance of your computer, causing erratic behaviour such as system crashes. At worst it can modify your data, delete valuable files and wipe out hard disks or make then totally inaccessible. It can cause a user a lot of time and money to fix up a problem caused by a virus.
Other types of malware can affect your PC in other ways. For example adware will display pop up advertisements and spyware may collect personal information about you that may go on to be used in identity fraud.
To prevent damage from viruses make sure you have an anti software program installed on your PC.
