No.
Avast is still detecting it but when I scan with AdwCleaner nothing is found and after running AdwCleaner the log shows nothing either.
Could you now run an OTL scan please and attach a screenshot of the Avast alert

[*]Click the Run Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.
[*]When the scan completes, it will open two notepad windows. OTL.Txt and Extras.Txt. These are saved in the same location as OTL.
[*]Post both logs
No Avast alert - its just detected when I scan.
“Error: The system cannot find the file specified (2)” appeared after I clicked Apply (Move to Chest).
Uninstall Optimiser pro, that is the root of the problem
When I open programs and features to uninstall, Optimiser pro is not on the list, is there any other way I can remove it?
Thanks
What was the full location reported by Avast then we can use OTL to kill it
C:\Windows\Temp\RegistryOptimizer.exe|>{app}\OptimizerPro.exe
OK that is in the temp folder and just needs emptying
Clear Cache/Temp Files
Download TFC by OldTimer to your desktop
[*] Please double-click TFC.exe to run it. (Note: If you are running on Vista, right-click on the file and choose Run As Administrator).
[*]It will close all programs when run, so make sure you have saved all your work before you begin.
[*]Click the Start button to begin the process. Depending on how often you clean temp files, execution time should be anywhere from a few seconds to a minute or two. Let it run uninterrupted to completion.
[*]Once it’s finished it should reboot your machine. If it does not, please manually reboot the machine yourself to ensure a complete clean.
Thanks again.
OptimizerPro is gone now, but my laptop is still extremely slow: “no virus found” when I scan (boot-time scan).
Any suggestions welcome.

It might be worth reducing your startup programmes to only Avast
Hi, I seem to be having the same problem though it’s not on a flash drive but on my system. I downloaded a free program that was supposed to help me extract mulitple files at once and the installer also added some adware and I believe that could be the problem but of course, I’m not an expert. I’ve run avast twice, once in the boot-time scan and it found Win32:Installer-U [PUP], but I didn’t let it finish…oops. I ran a full system scan and it found Win32:Dropper-gen [Drp]. Looking at it now, it looks like it also found Malware from one of the “offers” that was installed with the program.
Here are the file locations:
Uninstall.exe - C:\ProgramFiles\Uninstaller\Uninstall.exe - Win32:Installer-U [PUP]
Custom.dll - C:\ProgramData\InstallMate{99853496-E169-4392-A179-A94B42661660}\Custom.dll - Win32:Dropper-gen [Drp]
ExtensionUpdaterService.exe - C:\ProgramFiles\V-bates - FileRepMetagen [Malware]
I moved the Win32:Installer-U and Win32:Dropper-gen to the chest.
I scanned with OTL but it only left an OTL.txt log file. It is attached.
