FİRST OF you need your firewall back on.Download M/sofs Security Essentials,Uninstall AVG(preferably with REVO then use CCLEANER).Then install MSE.That may help you get Windows own firewall back up and running.Then go here http://www.eset.com/us/online-scanner/
On the left of the page,click on the blue button labeled Run Eset Online Scanner,,checkmark all appropriate boxes
including 'check archives'
click on advanced settings and checkmark ''scan for pottentialy unsafe apps'
disable your antivirus just before you start then reenable it afterwards.'The scanner will give you the option to delete anything it finds
at the end of the scan.Then go to Start>type prefetch in the Run box and delete everything there.

Reboot.İf defragmenting is needed please do that as well,then re-install M.Bytes and S.A.Spyware.İ'll go get you the links.Please report back.

Dear Julia,

I used REVO then CCleaner to remove AVG. Then I launch MS Security essentials but it is not possible to update the database. The virus slow down strongly the internet connection so I get a message that the update can not be down due to the low speed connection. In fact the connection is ok as I am contacting you with the same connection but another PC.
The tricks is I can not update any anti-virus with the computer infected.

Do you have any other idea ?

Thanks a lot !

Best regards

Yes,boot into Safe Mode and choose Safe Mode with Networking.Run the ESET scan from there.Then use CCleaner while still in Safe Mode CLEAN ALL TEMP FİLES,then click on the Registry icon on the left pane and click 'Scan for issues'click on Fix selected issues'click YES to the popup that appears,click SAVE.then CLİCK ON 'FİX İSSUE'ONE BY ONE.Delete everything.

Then delete everything in 'prefetch'

Reboot into Windows and see if this helped.Please make a note of whatever ESET finds.

PLEASE NOTE:İf none of the above suggestions solve the problem,please post here http://www.bleepingcomputer.com/forums/forum25.html and /or here http://www.bleepingcomputer.com/forums/forum103.html

Good luck.

You're welcome however if you gave details as to what exactly happened AND the full results of the ESET scan,would be helpful to others here.Also running FULL scans with M.Bytes and S.A.Spyware are STİLL desirable.
