Trojan.Zlob


Recommended Posts

Hi, hope you can help. Norton Antivirus told me that I had a Trojan.Zlob today - although my McAfee system did not give me an alert about it. I then initiated a scan using the McAfee system and it returned nothing. Still concerned, I downloaded Malwarebytes and initiated a full scan, and it returned no baddies. Could it be possible that the Trojan evaded Malwarebytes or do you think the Norton scan was a false alert?

This was the mbam script:

We have the fakealert/zlob families locked down good , likely the best of any application out there .

Only way to know for sure though would be to see a Hijackthis log .

Download and run Hijackthis :

Choose the "Do a system scan and save a logfile" option .

Copy and paste the log into your next post .

There is no Zlob/FakeAlert (or anything else for that matter) in your log .

IMO with the info you have given me the only logical answer is that Zlob attempted to run and was blocked before it ever had a chance to install .

A false positive is also possible and so is Norton hitting a long dead trace like a file in a old restore point . It happens from time to time that a new update will detect very old malware and hit something backed up in a restore point .

If you were to turn off system restore , reboot and then turn it back on this would flush all old restore points and make a fresh one eliminating this potential issue .
