unable to download and save files.

[john carey]

A few days ago I ran CCleaner registry cleaner. Now I can't download and save files from the internet. I get a message of:  "___ contained a virus and was deleted." please help! 

[nukecad]

Firstly - are you absolutely sure that the file you are attempting to download does not contain a virus/malware?

That message is typical of AV/AM applications blocking the down load of a malicious file.
Some browsers will also detect malicious files and block their download.

Of course it may be that you have deleted a registry entry that was needed by your AV/AM application.

Which version of Windows are you using, which AV/AM?

A screenshot of the error message may also help pinpoint where the problem is.

You should not use a registry cleaner with Windows 10, it changes too often for reg. cleaning software to keep up.
In fact Microsoft recommend that you don't use a registry cleaner at all:

I'm running windows 10. I've tried downloading several programs and mp3's.  I have AVAST installed but I disable it to rule it out.  What does AV/AM stand for?  I also took my computer in to BESTBUY.  They think it is the registry. My browser is MS EDGE. See the attachments.

AV - Anti Virus. AM - Anti Malware.

I does look you may have deleted something from the registry that you shouldn't have.

What I would try myself, in order:

You could try restoring from a restore point made before you ran the reg cleaner to see if that puts it back.

Try updating/refreshing Edge.

Try a Windows 'Search for Updates'

If nothing else works then get to the Windows repair menu (there's a few ways to do that, see Google for step-by-steps) and troubleshoot, repair, or even reinstall Windows 10 from there.

That Plain Edit program is deemed as being clean by both Jotti and VirusTotal (of course you can re-scan them yourself):

Does anyone know if there is someone I can speak with at Piriform CCleaner?  I tried looking for a Registry Backup File on my computer, but could not find one.  I know the problem that I am having was caused by the Registry Cleaner that I ran.  I have to wait until I hear from someone at CCleaner before I can use a registry fix program or before I can take my computer in to be repaired.  if I don't hear from someone that's okay as long as its fixed. Thanks for help.  John

Look in your Documents folder.

When you cleaned the registry, and CCleaner asked you to make a backup of it, did you say yes ?

[Andavari]

That's all assuming the .REG backup file would actually fix the problem, although it's worth a try.

If you have a relatively recent Restore Point that will allow Windows to fully restore the registry to a point before using CCleaner's registry cleaner.

[john carey]

I am not sure if I answered yes or no when I think back. maybe I thought there was no reason to keep it. I looked around my hard drive for anything with a .REG extension. See my attachment.  The most recent is dated 4-12-2018. Could one of those files correct my registry?.  Also, I purchased iolo System Mechanic Premium. Could this correct the problem?.

Please do not use System Mechanic. You should never use any Optimizer on your system. They cause more system damage than a lot of Malware and soon will be listed as such by Windows Defender. Having such a program installing on your system will just bloat it down and you have more chances to have issues. These types of software are advertised as a program that can solve all your issues, speed up your computer performance with a stupid figure. There is not a single program that can do that. You may be already in this mess because of simply clicking fix. The usefulness of cleaning the registry is highly overrated and can be dangerous. In most cases, using a cleaner to remove obsolete, invalid, and erroneous entries does not affect system performance but it can result in "unpredictable results".

One suggestion is you may be infected with "Zero access rootkit" which in turn if you are messing with the registry can hamper malware disinfection and make the removal process more difficult if your computer is infected. For example, removing malware related registry entries before the infection is properly identified can contribute to system instability and even make the malware undetectable to removal tools.

I am not allowed to ask for logs here so if you please follow Geekstogo which is the school I trained at.

You may not be infected. But without running a system analyst scan It's guessing in the dark.

Hey guys, a few things.  One this needs to move back to ccleaner, we're not an open software site, we're a user support forum for ccleaner. As far as I can see the software you're discussing is directly competitive to ccleaner.

Second, nicon, as stated by him, is getting close to rule 10 (see forum rules at the bottom of thread index).  We users cannot provide Antimalware advice and users are directed to seek professional help at a known antimalware site (such as bleepingcomputer or the geekstogo in his post).

[john carey]

I have not used,  iolo System Mechanic Premium. When I did not get any help from Piriform CCleaner,  I turned to a utility software. I wasn't going to use it. It was going to be my last resort. But, now I'm thinking I need a Registry fix program.  I'm going to return that utility software. 

[nukecad]

You don't need a registry fix programme. (It was using CCleaners registry fix that got you into trouble in the first place).

Using another programme is just likely to make your problem worse.

Have you tried the steps that I gave above?

Re-thinking the order than as your problem seems to be only with Edge the I would repair/reset Edge as a first try at a cure, see this article for how to do that:
https://www.winhelponline.com/blog/reset-microsoft-edge-browser-defaults/#repair_edge

In case you were not sure what I meant, or how to use a restore point then this article takes you through using system restore.
You won't need to create a restore point, you'll need to restore one that was made before you broke the registry.
https://www.windowscentral.com/how-use-system-restore-windows-10

If that doesn't work then you can try to troubleshoot, repair, or even reinstall using the Windows 10 'Advanced Startup' options.
This article explains those processes:
https://pureinfotech.com/access-advanced-startup-options-windows-10-troubleshoot-fix-pc/

If you are not comfortable doing any of the above (and it seems you may not be) then I suggest it's time to take your PC to a local technician who will be confortable with them and should get it sorted fairly quickly.
