Hi,
I've just come to the end of my current job so have some spare time to complete a project - information/unhooker/connections and scan for hidden objects tool.
I have also looked at various source and plan to use my own versions.
One I have looked at extensively is svv and plan to run with something from it, but have some problems that I'm wondering if anyone else have encountered, mainly in the results.
In a vm, xp playground I'm getting different results on a clean system. - System infection level = 0, nothing suspected was detected...as expected, to 5 - deepred Smile when scanning again.
Can anyone here, or mods, share any relevant experiences with svv, perhaps explaining the reasons why the results may vary.
vmworkstation, xppro.

In order to work, some types of software have to hook into the OS kernal. These typically are all firewalls, HIPS, some anti-virus and anti-malware software and virtual machines and sandboxes. So, it is scarcely surprising that SVV is finding the VM hooks. Having said that, I cannot explain why multiple scans are reporting differing results.

Hi,
thanks for replying PCBruiser. Yes, I always take note in whats hooking into the system especially after introducing something new, and as you have said legit entries will be in the results.
I did not presume to leave a log file, but if I may leave a paste of svv <check> without any details extension this will be short and show the two different results I've been experiencing.
If no one knows of a bug or known reason why this could happen with the information I have given I will just have a look at that system again, but at the moment I just cant see what is doing this.
Okay, maybe I will start over, but still investigate this incase I have found a problem with the scan but more than likely I'm over-looking something.

No, but thanks for the offer Smile
my worry was that there was an error but I've now found the reason for the two different results.
There is another check/a/m result which differs from the one above - and I know why.
There is no problem with svv just another factor - please feel free to close thread, thanks Smile
