Avast did not identify a trojan that MSE found and deleted. What is the problem. I thought I had a more complete protection.
No security program have 100% detection or zero false positives.
If new it may go undetected, or was it a false positive from MSE …
what was the full detection name given by MSE?
upload and test file here www.virustotal.com if tested before, click rescan for a fresh result
Post link to scan result here
Some information of the file name, location and the malware name given by MSE would also help.
What is telling you it was a trojan ?
It could have been a false positive by MSE.
It can also be that if it was a trojan, avast missed it because you have pup detection disabled.
