Hello:

I'm trying to determine if this system is actually infected with malware or if the AV/HIPS software is detecting a false positive. Initially, the computer did not have AV protection, so I immediately installed Sophos AV [v9.0] and ran a full system scan. Sophos detects something called "VBS/Autorun-AZO" that seems to revolve around a [suspicious] file called "svcl32.vbs", which is located in the "C:\Windows\system" directory. I did a search on this file, but didn't find any useful information about it. Being unable to "clean" the file, I decided to delete it, but then receive a login message indicating that the file cannot be found. Before deleting it, I sent the file to Sophos for analysis, but haven't heard back from them yet. I generated a "HijackThis" report in hopes of someone being able to recognize whether this is something that the AV software is unable to properly mitigate or determine if this is simply a false positive and hopefully how to eliminate the alert and subsequent pop-up from reocurring.

Thanks,

Robert Lindholm

Can you tell me how long the PC has been without real-time anti-virus protection?

So long, and thanks for all the fish.

Noviciate:

Hard to say, as this isn't my computer and the person who asked me to take a look at it, doesn't recall [sigh]; I think it had Computer Associates AV software installed at one point, but was recently removed and/or became non-functional. In all likelihood it has been without AV protection long enough to probably become infected. Any insights into whether the "HighjackThis" report output indicates a potential malicious threat(s) is/are present and how to remediate them [hopefully short of a complete re-install], would be greatly appreciated.

Thanks,

Bob

Given the lack of an active AV for an indeterminate amount of time, my best advice is to back up any important data and reformat and reinstall the operating system.
The possibility that legitimate files may have been infected or corrupted by the malware present on the PC, and also that security settings may have been lowered making your computer more liable to infection in the future, means that starting over is the easiest and most reliable solution to your problems.
You also need to be aware of the risk of identity theft if somebody has accessed bank accounts with this computer or shopped online. Keylogging software could have recorded details of these actions and I assume a lack of an effective firewall which also means that there is nothing to stop this information being sent home. If this does apply, i'd monitor any accounts accessed and perhaps consider getting credit/debit cards, passwords etc... changed - obviously not using this PC!
Should you want them, I can provide links to free software that will help keep your PC malware-free in the future.

So long, and thanks for all the fish.

Thank you for your recommendation; under the circumstances, that is probably the best course of action and I will pass along that suggestion onto the end user owner of this system.

As this issue appears to have been resolved, at least as far as a nuke and pave can be considered a resolution, this thread has been closed.

So long, and thanks for all the fish.
