Ok, thank you for your help. Here you have the HiJackThis report.
Later, i said was using the Kasperski suite. But i removed that. Since my parents have great difficults, accesing to the Internet withouth headache.
I've installed the AVG 8.0, instead. A friend a mine told me that is very good.
Enything else you need, just ask. Good luck, see'ya :).

Hi

Can't see anything malware related in log but let's do little scanning :)

Download ATF (Atribune Temp File) Cleaner© by Atribune (http://www.atribune.org/ccount/click.php?id=1) to your desktop.

Double-click ATF Cleaner.exe to open it

Under Main choose:
Windows Temp
Current User Temp
All Users Temp
Cookies
Temporary Internet Files
Prefetch
Java Cache
*The other boxes are optional*
Then click the Empty Selected button.

If you use Firefox:
Click Firefox at the top and choose: Select All
Click the Empty Selected button.
NOTE: If you would like to keep your saved passwords, please click NO at the prompt.

If you use Opera:
Click Opera at the top and choose: Select All
Click the Empty Selected button.
NOTE: If you would like to keep your saved passwords, please click NO at the prompt.

Click Exit on the Main menu to close the program.


Please run an online scan with Kaspersky Online Scanner (http://www.kaspersky.com/virusscanner). You will be prompted to install an ActiveX component from Kaspersky, click Yes.
The program will launch and start to download the latest definition files.
Once the scanner is installed and the definitions downloaded, click Next.
Now click on Scan Settings and select the following:
Scan using the following Anti-Virus database:
Extended (If available, otherwise Standard)
Scan Options:
Scan Archives
Scan Mail Bases
Click OK.
Under
select a target to scan
, select My Computer.
The scan will take a while so be patient and let it run. As it scans your machine very deeply it could take hours to complete, Kaspersky suggests running it during a time of low activity.Once the scan is complete:
Click on the Save as Text button.
Save the file to your desktop.
Copy and paste that information into your next post if the AV content will fit into one post only. Post a fresh hjt log too.
If the results of the anti virus scan itself will take more than one post to contain, you may upload it to http://rapidshare.com


Note for Internet Explorer 7 users: If at any time you have trouble with the Accept button of the license, click on the Zoom tool located at the bottom right of the IE window and set the zoom to 75 %. Once the license has been accepted, reset to 100%.

If having a problme doing the above

Make sure that your Internet security settings are set to default values.

To set default security settings for Internet Explorer:

* Open Internet Explorer.
* Go to the Tools menu, then choose Internet Options.
* Click on the Security tab.
* Make sure that all four item (Internet, Local intranet, Trusted sites, and Restricted sites) are set to their default settings.

Thanks to your response, i've noticed that i cannot use the on-line scanner you recommend. When i push the button of "accept", on the previous agreement window, nothing happens.
Also, i only can access to the configuration of Internet Explorer, from the icon on the desktop. If i try from the browser, a message informs that this option has been canceled by one Administrator.
If i try to download something from Rapidshare, using the free mode, i can't. The web site reports that my machine is occupied with an archive. No matter how many hours i wait, until that "download" finish.
And sometimes, my PC freezes in the middle of the shutdown process.

Hi

Let's try this:
Please download Malwarebytes' Anti-Malware (http://www.besttechie.net/tools/mbam-setup.exe) to your desktop.

Double-click mbam-setup.exe and follow the prompts to install the program.
At the end, be sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
If an update is found, it will download and install the latest version.
Once the program has loaded, select Perform full scan, then click Scan.
When the scan is complete, click OK, then Show Results to view the results.
Be sure that everything is checked, and click Remove Selected.
When completed, a log will open in Notepad. Please save it to a convenient location. The log can also be found here: C:\Documents and Settings\Username\Application Data\Malwarebytes\Malwarebytes' Anti-Malware\Logs\log-date.txt
Please post contents of that file in your next reply.
