What is a virus scan?
A virus scan is a process that checks your computer for viruses and other malware. This can be done using software that you install on your own computer, or by using an online service.
When you install virus scanning software on your computer, it will usually come with a schedule that you can set to have it automatically scan your computer at regular intervals. This is important, because new viruses are always being created, and you need to make sure that your software is up-to-date in order to find and remove them.
There are also online virus scanners that you can use, which can be convenient if you don't want to install any software on your computer. These services usually work by having you download a small file that they then scan for viruses. Once the scan is complete, the results will be displayed on their website.
