I went to a suspiciuos website the other day but my antivirus didn't detect anything back then (I'm using Avira). The next day when I turned on my computer, I had a pop-up message from Avira warning me of a virus. I ran other programs (like Malwarebytes, EMCO Malware Destroyer, Trojan Remover...) and they found nothing.
I also ran a complete system scan with Avira and it detects nothing. But it has the supposed virus quarantined, and when I go to quarantine and check it again, it detects it as a virus again. The name of the supposed virus is: TR/Virtool.INF.Autorun.241.66. It says it is in the catroot2 folder.
Is there a way to manually delete it without harming my computer? I recreated a new catroot2 folder, and Avira still detects it. Is it actually a virus or is it a false positive (since Avira is the only program to detect it)? If I remove it from Avira's quarantine folder manually, will I be removing it from my computer or will it go back to not be quarantined?
Excuse me for asking so many questions... ;)
