To search a file, click the Start button, and then click Search".Also a process called ppxcs.exe is using all of cpu performance.I cannot access to other programs due to this process.Could you plz help me solving these problems.

Hi Kishore, thanks for heeding my advice and starting a new thread.
I will be helping you clean your system. Hopefully, this will not take a long time.

Please download Malwarebytes' Anti-Malware 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 MBA-M finishes, Notepad will open with the log. Please save it where you can find it easily. The log can also be opened by going to Start > All Programs > Malwarebytes' Anti-Malware > Logs > log-date.txt.

Please post this log in your next post.

Please download the latest copy of HijackThis from Trend Micro and save it to your desktop.

• Double click on HJTInstall.exe to install it. Click on Install. By default, it will install to C:\Program Files\Trend Micro\HijackThis.
• Read through the License Agreement presented to you on the next screen and click on I Accept.
• Once installed, HijackThis will start automatically. If it doesn't, please go to your desktop and double click on the HijackThis shortcut created there.
• Select Do a system scan and save a logfile.
• Close HijackThis.

Please paste the contents of the logfile here so that I can see what's going on in your system.

i have the same problem hope it work for me

You possibly have a dodgy bit of script calling it, instead of regsvr32.exe. Possibly you should be pleased about that. If MBAM does not find it post a hijackthis log.

hi good day, administrator, i would like to as for your help regarding my start up problem, everytime i start up my laptop an error message appears like this "windows cannot find 'regsvr.exe'. make sure you typed the name correctly, and then try again. To search for a file, click start button, and then click search."
