I had a problem with an earlier version of CIS saying “the virus database is not updated” and/or “the AV engine is not started,” so I updated to the latest version 3.8.65951.477 db version 1039, heuristic scan set to “low,” and started to scan the main drive and the “restoral” drive setup by Gateway yesterday, 3/09/09. The Heur.Pck.tElock popped up several times, with different files, all of which had been on the PC for months to even years without incident. I submitted the files to Virustotal, and they were all OK. What was very strange to me was that on the analysis of the alcxsens.sys driver (a Sensaura WDM 3D Audio Driver) showed that Comodo had no problem with the file, yet my installation flags it as an error.
I have a very similar problem. Files that have been on my PC for ages are showing exactly the same message during a scan. VirusTotal did have a couple of reservations, but Comodo was not one of them. But like the OP, CIS is returning a positive when I scan and also when I tried to send to VirusTotal.
You can add the file to exclusion list and send the file to us
A File can be added to exclusion by
1.Launch CIS and navigate to Antivirus → Scanner settings-> Exclusions
2.Click ‘Add’-> Select → Browse ->select the corresponding file and add it to the exlusion list
Now you can zip and submit the specified file.
To include back the file from exclusion,
Launch CIS and navigate to Antivirus → Scanner settings-> Exclusions
Highlight the corresponding file from the exlclusion list and click Remove
I have CIS v. 3.8.65951.477, db version 1117, and it’s also flagging alcxsens.sys as being infected by heur.pck.telock, even though it’s been there a long time. It started a few weeks ago. Doesn’t happen every time I reboot, just sometimes. Never detects it when I actively scan the file in question. Last time the popup happened I tried the option to add it to a Safe List (sorry don’t remember the exact words). Today when I logged in I got it again, so I tried the other option of Adding to Exclusions. I also had reinstalled the driver after the initial detection, since I let CIS remove the file and only later (when my sound stopped working) discovered it was my sound driver. Should I send this file?
