@nukecad: thank you, it's important to know that it's not really a 'virus infection'. I'll try again tomorrow.

Kaspersky detected : Event: Malicious object detected Application: ccupdate606_free.exe User: xxxxx User type: Active user Component: System Watcher Result description: Detected Type: Trojan Name: PDM:Trojan.Win32.Generic Threat level: High Object type: Process Object path: e:\program files\ccleaner\temp_ccupdate Object name: ccupdate606_free.exe Reason: Databases Databases release date: Today, 16/11/2022 10:59:00 The program was totally removed by KIS, I reinstalled the old version 6.05.10110 I did not have that problem on Windows 11, only windows 10, strange .... Please advise. Thank you.

Same things is happening to me !

@Andavari : thanks for the link to the pdf, I saved it; Under application control Piriform is and was under trusted applications. The problem was with system changes and I had to allow CCleaner to make changes, like explained by mta, in order to have cookies etc. cleaned.

All PC's have the same version of CC, KIS and windows. So now I clicked to always allow CC on the PC in question ! Problem solved..... I hope. Thanks.

Thanks for your reply, it makes sense but ...... this is only happening since I updated CCleaner and on one computer only, KIS 2016 is installed on all computers, OS Windows 7 Home Premium 64bit, with System Changes Control enabled.

Hi, Since I updated CCleaner to version 5.10.5273, every time I use the application I get a warning from Kaspersky : "canceled change of google chrome settings by CCleaner" The application was not allowed to change the browser configuration file. I really wonder what it means and what can be done. Do I have to worry about it ? Thanks.

Thank you !

I have the same problem. I suppose (hope) it's a bug, it occurs on all the computers !

Great !

Maybe not, but the virtualized folder is just the thing that makes the computer slow down, and adding it NOT to be removed is probably not a good idea as well. Mind you when the computer is restarted IE is back in "protected mode". For the moment I'll leave it on and surf with Google Chrome which is getting an update tomorrow (11 patches)and use alternatively IE and Chrome, according to the protection I need to have for a particular task, like downloads etc.

Hello, In the meantime, the solution suggested by Blue Medicine works like a charm. Leave UAC on and disable protected mode in IE8, no more virtualized folder. To be safe I surf now with Safe Run from KIS. Thank you all for your kind reactions.

Hello Aethec, Finished the KIS scan and nothing was found. Strange things happen to computers, but this is beyond my comprehension. That C\ folder seems not to reappear (deleted it) but nevertheless I'm sure it will be recreated soon enough. I cannot find it on the laptop either but I don't use this one extensively. Thanks for your reply. In the meantime I submited a HJT log in the forum of Blue Medicine, that will take some time to get a reply there, and .... that virtualized folder came back with a vengeance, almost an exact copy of the thumbnail cache and slowed down Internet Explorer again, deleted it. Drives me nuts. UAC maybe for safety and clicking OK if I want or not open some file or program does not disturb me but filling the memory is.

The thing was : typing "on line" like now, it's like the text "had" a delay in showing up and with UAC disabled I never had that, it seems better now. Maybe you're right about an infection, did a malwarebytes scan already and did not find anything. I had no idea about that virtualized folder until yesterday CCleaner came up with such a huge file that I went looking for details. Surfed around this morning, disabled the 24 hours thing on CCleaner and so far it did not find any of that stuff again..so I suppose it's only generated in connection with a specific action, download or searching, don't know. Also yesterday I tried to install the new version of HJT and got the warning that it could not be installed on a non-existing drive (probably that C file) today it went OK but have to run the app as administrator in order to get it working, did that but it says that HJT is already running, I suppose restarting the computer might solve that. Every day the computer is scanned by mbam and KIS's quick scan and nothing was ever found. I will perform a full scan now with KIS and wait for the result.

@Nergal OK, I did disable it, I will reneable it but .... it slows down the computer so much and even when typing on line the text appears a few seconds after typing. I did enable it due to the MS DLL thing. Is there any way to avoid this, I use Ccleaner many times during the day. My system is Vista Home Premium SP2 and I cannot use the secpol thing to configure UAC, and it's not only the virtualized folder some compatibility folder is some apps is also appearing, some apps have to be opened as administrator or it's impossible to save changes in some 3D progs.
