Please download the Gromozon Removal Tool from here:

Gromozon Removal Tool

Save it where you can find it.

DO NOT RUN IT YET.

Reboot into Safe Mode

You may want to print these instructions here or save them in notepad since you'll work offline

To enter Safe Mode..

Click start > turn off computer > Restart > When you hear the computer beep once, begin tapping F8 rapidly > this will bring up a menu > use your keyboard to scroll to safe mode > hit enter
==========================
Please run the Gromozon Removal Tool, and follow the prompts..

then, Boot normally.

Post a new HijackThis! log into this thread, and describe how the PC is behaving at the moment.
Post #4
Ok. Done.

First during Gromozon Removal Tool was running a pop-up showed:

The Trojan.Gromozon rootkit component was non found on the system


After reboot two pops-up:

1) "Error in the RWQL1.EXE" file;
2) "The RWQL1.EXE program will be terminated"

So finally the Hijachthis log

Open Windows Explorer by hitting your windows key + E at the same time.
*If you do not have a windows key, double click My computer > click the folders icon

Then navigate to these files and delete them:

C:\WINDOWS\Temp\rwql1.exe

Empty your recycle bin

Reboot

then, post a fresh hijackthis log along with a description on how your machine is running.
