I have uninstalled (with AVG uninstall tool and Revo Pro) AVG ultimate on 1 of my PC abd installed Bitdefender.
I'm very surprised because BDTS detected 2 AVG files
Do you think they are false positives?
Freud2004 is completely correct.
Please note that updaters for antivirus programs often contain detection signatures. These detection signatures are the very same patterns other antivirus scanners use to detect malware. Because they contain malware patterns, false positives on antivirus software are very common and nothing to worry about.
Especially if it is only one engine on VirusTotal.
