With correct installation of CIS there is no way for SmartFortress to bypass that. Whether it was sandboxed - after restart it should be gone. I bet you have even not restarted the system
Seriously, what is the "correct installation of CIS"? I am afraid to say that SMART Fortress bypassed everything. After I discovered it on my PC/Desktop I ran a scan with Comodo a couple of times and needless to say, I restarted my PC a couple of times.
Unfortunately, I cannot upload any more information about the 'Malware' as I have cleaned it all with Malwarebytes. By the way, there is no other protection on my Vista. And as far as I know, CIS is configured properly and it has served me well in the past years.
I never said Comodo was 100% foolproof. I did not intend to bad mouth CIS but to bring the fact to the forum's notice. I am still a fan of CIS.
I hope CIS will not disappoint me in future, at least not big time.
