here is my two cents:
Stinger would work even if you are offline (not connected to internet)
Stinger scans for rootkits, running processes, loaded modules, registry and directory locations known to be used by malware on a machine to keep scan times minimal. I would further recommend you to run scan in safe mode and also customize it to run scan on all the local drives. Refer Link
Stinger leverages GTI File Reputation and runs network heuristics.
GTI File Reputation technology extends the protection capabilities of McAfee products by providing access to an online cloud database containing file classification details to determine whether a file is malicious. Because the database of malicious file classifications is extensive and changes frequently, GTI File Reputation queries the online GTI cloud servers about potentially suspicious files to achieve and maintain the highest security levels.
If you are still apprehensive of running stringer scans while you are online. I would suggest you to run two sets of scan. First without network access and second with network access.
Hi Peacekeeper, thanks very much for the quick reply.
I have gather advises from other forum to remove the lan cable to Pc before doing the scan for virus, malware, spyware (vms), if not these vms will somehow disturb the scanning and not able to destroy any of it.
So could you please advise when using Stinger, should I unplug the lan cable?
