In a hurry? Here are the top 5 online virus scanners: Users on a budget can download the free version of Avira, or you can follow my recommendation for the top antivirus software and pick up any of the low-cost Norton 360 packages.īut if you just need a quick answer as to whether or not you are infected, these tools will help. Personally, I wouldn’t turn my computer on for a minute without a high-quality antivirus software installed.

Fortunately, there are a few really useful online cybersecurity tools, plus a few one-time downloads that can actually help you clean up your computer. I hate to tell you this, but there are almost zero online virus scanners. Most of them are just trial versions of paid software, a lot of them don’t really do anything, and some of them are phishing sites trying to steal your data or convince you to download malware.
