dear friend i understood your problem there is nothing special to do just format your laptop pslb84-027025 becausethe problems you have to face is due to virus program attacks to your laptop some times an antivirus program unable to find the viruses so i suggest you to format your laptop.

NOTE:keep the back up of the drivers , or you don't have? just go to www.notebookera.com then select your device then download the drivers related to your device.

thank you for give me chance to help you,

please give your ratings!

I would suggest try avoiding formatting. Because if you do that, then the next problem you will face is to find, download and install all the drivers.

If you are using the Genuine Windows operating system, then download 'Microsoft Security Essentials' for free from the Microsoft website. This should take care of your viruses.

Second get the latest Service pack provided by Microsoft and this should update the drivers.

And basic things, like removing unnecessary files, Defrag you hard disk, etc should also add up to the speed.

How Can I Remove the Sasser worm?

Follow these steps in removing the Sasser worm.

1) Disconnect your computer from the local area network or Internet

2) Terminate the running program
Open the Windows Task Manager by either pressing CTRL+ALT+DEL, selecting the Processes tab or selecting Task Manager and then the process tab on WinNT/2000/XP machines.
Locate one of the following programs (depending on variation), click on it and End Task or End Process

avserve.exe
avserve2.exe
skynetave.exe
any process running with the "_up.exe" suffix
Close Task Manager

3) Activate the Windows XP Firewall (if running Windows XP) or another firewall to prevent the worm from shutting your system down while downloading the patches. To activate the Windows XP firewall, follow these steps.
Click on Start, Control Panel
Double-click on Networking and Internet Connections, then click on Network Connnections
Right-click on the connection you use to access the Internet and choose Properties
Click on the Advanced Tab and check the box
"Protect my computer and network by limiting or preventing access to this computer from the Internet"
Click OK and close out of the Network and Control Panel

4) Remove the Registry entries
Click on Start, Run, Regedit
In the left panel go to 

HKEY_LOCAL_MACHINE>Software>Microsoft>Windows>Current Version>Run

"avserve.exe"="%Windir%\avserve.exe"
"avserve2.exe"="%Windir%\avserve2.exe"
"skynetave.exe"= "%Windows%\skynetave.exe"
Close the Registry Editor

5) Delete the infected files (for Windows ME and XP remember to turn off System Restore before searching for and deleting these files to remove infected backed up files as well)
Click Start, point to Find or Search, and then click Files or Folders.
Make sure that "Look in" is set to (C:\WINDOWS).
In the "Named" or "Search for..." box, type, or copy and paste, the file names:

avserve.exe

skynetave.exe
C:\win2.log
Click Find Now or Search Now.
Delete the displayed files.
Empty the Recycle bin

6) Reboot the computer and update your antivirus software, and run a thorough virus scan using your favorite antivirus program.

For Automatic Removal of Sasser, download the Symantec removal tool, you'll still need to download the patches above and install them, however this removal tool will stop the Sasser worm from running, remove the items in the registry, and delete the infected files.

it sounds like your virus protection has expired and you may have a firewall up blocking the internet connection.

two options: pay mcafee the yearly renewal or go here http://www.download.com/AVG-Anti-Virus-Free-Edition/3000-2239_4-10320142.html?part=dl-10044820&subj=dl&tag=button&cdlPid=11009475
and download a free professional antivirus, anti-spyware, and extensive firewall.

if you do download the new FREE program, make sure you completely uninstall ALL virus and spyware programs you may already have installed. Including Mcafee.


after youve decided what you will do and finished that part. open your web browser, go to internet options, advanced, and reset to default settings. then select the security tab and set to normal.

you should be all set!! Good Luck
