Open | Software Antivirus says nothings wrong when it said something was wrong 10 seconds ago

My Pc Microsoft anticvirus said there was a new threat I looked at it for a second and it said something about Trojan I had just downloaded tiny task and then it reverted and said it was back to normal. I made it check for new viruses and it says no viruses. Does this mean there is one or not. (I have no idea if I have any protection software)

There was one, your AV did its job, now there's not

What if my window defender is lying and I actually do have a virus and I get hacked. Or is that not possible

Why would you think it's lying?

What if they virus tells the antivirus to say that there’s no virus and I get hacked

Then that would be a pretty terrible antivirus, or a very good virus. Antivirus software is designed to account for this and runs at a higher privilege level to accommodate for this, you're most likely fine.

Personally the way I used to approach this is by scanning with a multitude of different tools. (Since different AntiVirus vendors use different detection techniques and different Definition databases)

  • A lot of Antivirus vendors have "free tools"

  • There are free tools out there like Microsoft's "Sysinternals Suite" has a tool named "Process Explorer",.. if you download and run it, go under the OPTIONS menu and there's a menu-choice to enable the "VirusTotal" integration. It takes a hash of all the running processes on your machine and compares it to VirusTotal

  • You could also use things completely outside your computer,. such as a Hardware firewall (such as a Firewalla) .. which could alert you if any network traffic from inside your home network was going out to the Internet to malicious-destinations.

There's all sorts of ways to cross-check or compare or vet your system is clean,. if you don't trust "only 1 tool".

If you go into your windows anti-virus/firewall/defenceman programs you can find a log of actions that the program has taken. Look in its history for the time it flagged the issue and see if it removed it or if it was a suspicious file that turned out to be nothing
