Hello to all. First of all I would like to thank you in advance for trying to help me!

The problem is the following: Yesterday I ran a scan with SpyHunter and it found 25 entries in my registry of the trojan Zlob. After removing them, I cannot open any Taskbar and Start menu items. Here is the Hijackthis log:

Please, help!!!

Heya, CC... did you mean to mark the thread solved already?
Start hijackthis, select Scan Only, place checkmarks against all the entries listed below that still exist, and then press Fix Checked.

O4 - HKLM\..\Run: [startkey] C:\WINDOWS\system32\winsystem.exe
O4 - HKCU\..\Run: [startkey] C:\WINDOWS\system32\winsystem.exe

Good. Now browse to this file and delete it: C:\WINDOWS\system32\winsystem.exe
Report back with an update on your problem.
