    You need to clean your network from virus. Get your antivirus updated and clean your network. After doing so, reinstall your yahoo messenger software.

You could have been infected with a trojan virus. There are many kinds of trojan variants that runs within autorun.inf to mess up with your hard drives.

Technically it attacks the %System%, which is the C:\Windows\System32.

You can try fixing it manually by removing it on your registry:


and try deleting the suspicious string value of the trojan variant that comes with an extension file name of .exe or .dll.

If you did it and it comes back, my guess is that the trojan virus has already triggered itself with the System32 folder.

The best solution could be turn-off your system restore that could be found on system properties. Next, try to download "QuickSMASH.exe" then run this program.

If you wanted to be sure, try to update your AntiVir, (if ever you got one) then try restarting your computer and boot your system on safemode by pressing F8. Then run a complete scan on all of your local drives. If your done, try restarting your pc and turn on your system restore again.


BTW, you can also try turning-off the autoplay or autorun everytime you insert a flash drive on your pc. This could prevent an autorun.inf trojan virus that trigger itself to run on your system unsuspectedly.

To turn off autoplay, run the RUN Command and then type gpedit.msc ( .msc stands for Microsoft Console). After running it, click the Administrative Templates and then click the System folder on the right pane look for "Turn Off Autoplay" and double-click it. Click the radio-button "enabled" and from the drop-down list click "all drives" and click apply and ok and close the gpeditor.

When i am on ym mobile friends can see what i write to them but it will only come back to my pc even if i am signed out on pc??????????

It's because you can receive only two messeges from your friend in your mobile. Rest will be forwarded to yahoo server as offline messages. When you login again on pc you will get those messeges in pc as offline messages from server.
