The best solution is, you have to download latest MWAV virus scanner (not escan), which installs just instance and scans as emergency basis.
When the menu comes, select All Local Drives and again select Scan All Files in SAFE MODE. After full scan, again select the 1st option then select Program Files and restart the computer in Normal Mode.
Don’t worry, it is totally free and down able. If u getting problem to find MWAV, u r feel free to contact me.
If the problem persists then you have to format or repartition ur system.
Hope this will work for you.
Viruses and other malicious software programs have the ability to hide itself as if it is a legitimate software. If you think that your computer system is really infected with w32.stuxnet virus, you have to scan it using your installed antivirus software. If you don’t have an antivirus software, it would be hard for you to recover your system which has been already infected.
