What Is a Safe Online Security Scan?
A safe online security scan is an antivirus program that is designed to work within a Web browser. You don't need to download software because the security scan detects viruses on your computer by running the scan online. Most online security scans are free. But they are limited to simply scanning computers, not fixing problems or eliminating viruses.

Identification
-
An online security scan is a function of an antivirus program that is run entirely through a Web browser. The security scan searches for viruses and spyware, programs installed in your computer often without your knowing that can track your activity online and capture sensitive information. An online security scan is up to date with the latest virus information. Because you don't need to download software, the entire process can be done simply through an Internet connection. Some providers require a certain browser (for example, IE 7 or higher), and many offer this service free.
Benefits
-
Online security scans can be run online even though you may already have a antivirus software installed on your computer. You may want to double-check your current protection in case you suspect your antivirus program is not up to date or not working. Security scans are faster than locally installed antivirus programs because installed programs run through a database of viruses that is checked, whereas security scans host the database online. Also, because the database is online, it is continuously updated, supplying you with the latest virus protection in most cases. A security scan notifies you if it finds viruses and spyware on your computer.

Time Frame
-
Depending on the size of your hard drive and type of scan, the time it takes to complete a security scan can vary considerably. Most locally installed antivirus programs can take several hours to complete a full scan. But online security scans are much faster and can take as little as 30 minutes to complete a full scan.
Misconceptions
-
A misconception about online security scans is that they detect and delete viruses. But most online security scans simply detect. To deal with viruses, you need to purchase antivirus software or services.
Another misconception is that online security scans are foolproof and will always detect if spyware or viruses are on your computer. Some online security scan programs only raise a flag and detect a virus if it is active. If it is not running, a virus may not be detected. Running multiple scans from different providers or a locally installed antivirus program ensures greater protection.
Warning
-
Using an online security scan is a one-time scan that can detect viruses on your computer. It is not a replacement for an antivirus program that is running in the background constantly guarding you against viruses and attacks. Online security scans also require connection to the Internet. And if you are connected without a firewall to guard against online intruders, you are at high risk of being exposed to attacks. Connect to the Internet with a firewall in place, then use an online security scan, if needed.
