A virus scan is a process used to detect and remove malicious software (malware) from a device, such as a computer, phone, or tablet. Malware can include viruses, Trojans, worms, ransomware, spyware, and other threats that can damage your device, steal personal information, or even take control of it.
How does a virus scan work?
A virus scan works by comparing the files on your device with a database of known viruses. If a match is found, the antivirus will quarantine or delete the infected file.
There are different types of virus scans:
- Full scan: This type of scan examines all files on your device. It is the most thorough type of scan, but also the most time-consuming.
- Quick scan: This type of scan only examines files that are more likely to be infected. It is a faster type of scan, but less thorough.
- Custom scan: This type of scan allows you to select specific files or folders to be scanned.
When should you run a virus scan?
It is recommended to run a virus scan regularly, such as:
- After installing new software: Pirated software or software downloaded from untrusted sources may contain malware.
- After opening an attachment from an unknown email: Attachments from unknown emails may contain malware.
- If you suspect your device is infected with malware: If your device is running slow or experiencing unusual errors, it might be infected with malware.
- After clicking a link from an unknown website: Links from unknown websites may lead to websites infected with malware.
It is important to have an up-to-date antivirus installed on your device so it can detect and remove the latest threats.
In addition to running regular virus scans, it is also important to take other measures to protect your device from malware, such as:
Using strong and unique passwords for each account.
Not opening attachments from unknown emails.
Not clicking on links from unknown websites.
Keeping your software up to date.
Backing up your important data regularly.
By following these steps, you can help keep your device safe from malware and your data secure.
