A Trojan was detected in favicons.sqlite-shm by BitDefender, the report said it blocked it (see screen-cap). Soon after, I wasn't able to load Firefox, Opera Browser and Thunderbird. Tying to access them would start a popup dialog box stating that"Firefox is already running" and I'd would be asked to either cancel or stop. Pressing either option wouldn't allow access to Firefox etc., I had my computer scanned professionally and was told they didn't think the Trojan was still active and they managed to restore access to Firefox and Thunderbird, this took 2 hours.
I remain unconvinced my computer is free of the Trojan for various issues, including a corrupted winload.efi file (I have already attempted and failed to fix this) that won't allow Windows Defender to scan in Offline mode. Various other issues such a slow applications and occasionally flickering screen suggests the Trojan might still be active.
I'd greatly appreciate if anyone has information or experience dealing with particular issue.
Scans such as, Kaspersky, Malwarebytes, Bitdefender, etc. have been run and found nothing.
