Website may have bit me; now scans are too fast
I have multiple PCs running W-7 with F-Secure, Malwarebytes Pro and Malwarebytes Anti-Exploit free.
Everything was running fine on PC1, but then I looked for statistical information and looked at one website. At the bottom was a link which read "stats.bls.gov" which appeared to be safe. I could have sworn I cut-and-pasted it rather than clicking on it, but maybe my OpSec was lax. The webpage which popped up was "stats.bls.gov.com" which immediately alerted me that I had been hijacked. I did not click on any links on that page. I killed the browser (IE11) and started MBAM. The color of the GUI was not green, telling me that something was wrong. I looked through the settings and noticed that Malicious Website Protection was OFF. I turned MWP back on.
I checked "stats.bls.gov.com" with VirusTotal and it indicated no problems.
F-Secure gave no visual warnings. I ran a full system scan with it. It said nothing was found but it only ran for about 10 seconds. Normally a full system scan takes maybe five minutes (this is an SSD).
Then I started a full custom scan with MBAM including rootkits. It ran for 22 seconds and then stopped with the Nothing Found message. I rebooted and tried to scan again. Same result.
I rebooted into Safe Mode and ran a full custom MBAM scan including rootkits. It ran for 15 minutes which is as expected. Nothing was found. I rebooted in normal mode and ran another full custom scan: 22 seconds. Then I ran a threat scan which took two and a half minutes. Full custom scans will not complete.
I scanned the system using Microsoft Windows Defender Offline, but it found nothing on a full custom scan.
It would have been nice if I could have scanned using F-Secure in Safe Mode, hint, hint.
On another, identical system, F-Secure and MBAM scans take the usual time. Something has happened. The fact that F-Secure and MBAM scanners are quick is bothersome.
Any comments before I wipe the disk and start again?
