What started happening was that my system would crash, and the blue screen of death (BSOD) would appear whenever i did certain actions, like adjust the volume when playing youtube videos, run a search for any file on the system or even conduct a system scan with an anti-virus software. (P.S. Norton Anti Virus and Internet Security sucks big time, use either Kaspersky or BitDefender)

The message on the blue screen was “A driver has over-run a stack-based buffer. This over-run could potentially allow a malicious user to gain control of this machine” and the BCCode was 7F. Armed with this information, i set out to search the internet and find out if other people are having the same problem. I discovered that lately, its become quite an epidemic and is the sign of a new virus on the loose. A trojan by the name of Zlob!

What you need to do to remove it, is search for tdidrv.sys file in %windows%\system32 folder and delete it. (Bitdefender reports it as a rootkit, when it finally did detect it) and search your registry for its entry and delete it as well. (Located at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\tdidrv32.sys)

Alternatively you could use malwarebyte’s anti-malware to clean the system for you.

Thanks to TechSupportGuy forums for all the help.
