5 Best Online Virus Scanner

Now, more than ever, everyone should put online security on top of their concerns. Malware and viruses are becoming more and more dangerous and damaging. Once a mere annoyance, these threats can affect anyone by stealing their identities, infiltrating their systems, and even access their bank accounts.

That is why it is necessary to put safety measures everywhere. Installing primary antivirus programs and internet security suites can decrease the likelihood of infection. 

These programs usually scan your whole system and even target specific files. However, they can be slow and burdensome to the system at times.

What if you just need to scan a file? Or check if a particular website is infected?

Advantages of Online Virus Scanner

Using online virus scanners offer several benefits. First, most online virus scanners are free. Some may have limited functions, but they are still useful especially if you just want to scan a particular file. Additionally, online virus scanners are always updated. Developers can add updates and upgrades to their systems without having the users download it every time.

Moreover, unlike your standard security suites on your computer, online virus scanners can utilize multiple scanners on their servers. Most, if not all, will use services from other security programs which scans your files at the same time. Some viruses and malware are smart enough to fool or even halt the operation of the installed security suite. Online virus scanners can avoid this scenario and catch well-hidden threats.

Here are some of the best online virus scanners.
