Today I got some strange messages in zonealarm log. Task manager tried to delete zonealarm files: vsmon.exe and zatray.exe.

I am using zonealarm free antivirus and firewall:

ZoneAlarm Free Antivirus + Firewall version:
Vsmon version:
Driver version:
Antivirus engine version:
Antivirus signature DAT file version: 1120822112
Web Identity Protections version: 1.5.393.22

I also attached a screenshot from zonealarm log.
