[Solved] Internet - Download Error - Cannot download anything from the Internet

Hello.
I have such a problem ... the point is that I can't download anything from the Internet ... the problem is probably windows defender which I have somehow turned off and now it cannot be turned on again. When downloading, no matter what file, the message "Failed - anti-virus scan failed" pops up. Is there any way to activate this antivirus through the registry or some other way? If I downloaded another antivirus, would it work and I would be able to download files?

The mystery is what operating system you have. On another computer, download https://pl.malwarebytes.com/ and https://pl.malwarebytes.com/adwcleaner/ and scan yours.

Windows 10
I did a scan:

Zeskanowane, niestety problem jest dalej.

Include in the attachment scan logs from FRST (Frst.txt and Addition.txt):
http://www.bleepingcomputer.com/download/farbar-recovery-scan-tool/

Scan from this program

One more addition!

Addition please

Next to frst.exe, create a Fixlist.txt file with the contents:
HKLM \ SOFTWARE \ Policies \ Microsoft \ Windows Defender: Restrictions

I do not know if I did everything correctly, but I made the file, entered it all, the program repaired ... but unfortunately I still can't download anything because there is a failure at the very end (scanning ...)

This message is displayed in all browsers IE, Firefox, Chrome? Or only Chrome?

If only in Chrome, download the bookmarks, uninstall Chrome and delete the profile directory from C: \ Users \ artur \ AppData \ Local \ Google \ Chrome \ User Data \ Default, reinstall Chrome after it is done.

Ie. this message was from this program, and unfortunately I have a problem with downloading on every browser.

Run regedit, go to HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Policies \ Attachments and change "ScanWithAntiVirus" (REG_DWORD type) from 3 to 1

Thanks, it finally works and I can download files.

Added after 50 [seconds]:

All methods are fast and at the end a change in the register, as my colleague suggested.
