Download Ccleaner For Windows Server 2012 R2

So CCleaner never connects to the Security server as the image shows. no idea how to fix this. Also, the help link to talk to CCleaner team is just circular and never takes you to the option to email for help (quite frustrating).

There do seem to have been a few server issues for some users this past week. (in the USA? I haven't seen a problem here in the UK)

If/when it's a server at fault then all you can do is keep trying until someone fixes the server.

Normally I'd also suggest that it might be your Antivirus/Firewall settings that could be blocking the required server, but as your screenshot shows that CCleaner is reaching the server for the 'Speed' function then such an AV block is less likely here.

Thank you for your response, been a number of months now, want to say around 3-6 with no connection to Security server. I have tried uninstalling and re-installing and updating to no avail. I will email customer service.

That's just a older, not strictly accurate, message in Software Updater (I should perhaps have warned you about that message). Health Check is more accurate in saying that you cannot reach the server.

It's the same server in both cases.

As it has been going on a fair time for you then that does tend to indicate that it is not a server fault, and so most likely to be at your end.

As you have uninstalled and reinstalled CCleaner then it's unlikely to be a faulty install.

If you do have a AV installed then make CCleaner an Allow/Exception in the AV so that the AV then leaves it alone.

Check again to see if Health Check (or Software Updater) can now connect to the server.

on the other hand, i do tweak some things on my computer and maybe one of my tweaks is responsible for causing the problem, though, again, the software updater-thing worked fine, for me, up until one of the recent ccleaner-updates.

Hi, I have the same problem. I am in the UK, I have CCleaner Professional (Premium) so it is running on 2 desktops and 3 laptops, laptops on Windows 11 and desktops on Windows 10. Everything is up to date, windows, software, drivers etc. All devices have this issue where the Security part of Health Check and Software Updater part of Tools do not work. Security says "Unable to reach server" and Software Updater says "It seems like you're offline". I use Sophos Home anti virus and can not see an option to allow the CCleaner app and all apps should be allowed. If there is a specific file I can exclude it from the scan but I can't see that being the issue.

We are currently running 3 different virtual machines with the Windows Server 2019 OS. Is there any recommendations for a PC cleaning software such as CC Cleaner that we can run on these servers to improve to storage and how the servers run?

It just means that Health Check cannot currently check if some of the other apps installed on your computer have an update available.

It's been reported upwards and hopefully it will be fixed soon if it is a server problem.

When using Health Check Security Box displays "Unable to reach server" thought this issue was fixed. It is still occurring. Security is highly important so please help to urgently fix this issue. would be much appreciated.

The error is though to be caused by incorrect information coming from the server of one of the applications that CCleaner has found has an update available for.

Whilst some have been sorted out in the past, it's always possible that yours is on ethat wasn't caught, or than an application is now giving new incorrect information.

Then- Have you made any changes to your firewall settings, either through Windows or a 3rd party app?

We are aware that some CCleaner users set their firewalls to stop CCleaner 'Phoning home'.

That can stop some of the features from working because they need to 'Phone' various servers to work properly.

PS. For others reading- If you have a similar problem that only started happening this week then it may be related to this fire at a major server centre in Europe:

Talos recently published a technical analysis of a backdoor which was included with version 5.33 of the CCleaner application. During our investigation we were provided an archive containing files that were stored on the C2 server. Initially, we had concerns about the legitimacy of the files. However, we were able to quickly verify that the files were very likely genuine based upon the web server configuration files and the fact that our research activity was reflected in the contents of the MySQL database included in the archived files.

In analyzing the delivery code from the C2 server, what immediately stands out is a list of organizations, including Cisco, that were specifically targeted through delivery of a second-stage loader. Based on a review of the C2 tracking database, which only covers four days in September, we can confirm that at least 20 victim machines were served specialized secondary payloads. Below is a list of domains the attackers were attempting to target. Not all companies identified in the targets .php file were seen communicating with a secondary C2 or had a secondary payload deployed.

The contents of the web directory taken from the C2 server included a series of PHP files responsible for controlling communications with infected systems. The attacker used a symlink to redirect all normal traffic requesting 'index.php' to the 'x.php' file, which contains the malicious PHP script.

In analyzing the contents of the PHP files, we identified that the server implemented a series of checks to determine whether to proceed with standard operations or simply redirect to the legitimate Piriform web site. The contents of the HTTP Host header, the request method type, and the server port are checked to confirm that they match what is expected from beacons sent from infected systems.

There is also functionality responsible for loading and executing the Stage 2 payload on systems that meet the predefined requirements, similar to functionality that we identified would be required in our previous analysis of Stage 1. While there is shellcode associated with both x86 and x64 PE delivery, it appears that only the x86 PE loading functionality is actually utilized by the C2 server.

The C2 MySQL database held two tables: one describing all machines that had reported to the server and one describing all machines that received the second-stage download, both of which had entries were dated between Sept. 12th and Sept. 16th. Over 700,000 machines reported to the C2 server over this time period, and more than 20 machines have received the second-stage payload. It is important to understand that the target list can be and was changed over the period the server was active to target different organizations.

During the compromise, the malware would periodically contact the C2 server and transmit reconnaissance information about infected systems. This information included IP addresses, online time, hostname, domain name, process listings, and more. It's quite likely this information was used by the attackers to determine which machines they should target during the final stages of the campaign.

Based on analysis of the 'Server' database table, it is obvious this infrastructure provides attackers access to a variety of different targets. Given the filtering in place on the C2 server, the attackers could add or remove domains at any given time, based upon the environments or organizations they choose to target. To provide additional perspective regarding the types of systems that the attackers could choose to further compromise, the screenshot below shows the number of total entries that were contained within the database table used to store system profile information:

The purpose of the trojanized binary is to decode and execute this PE in registry. This PE performs queries to additional C2 servers and executes in-memory PE files. This may complicate detection on some systems since the executable files are never stored directly on the file system.

If you opt for Wise Diskcleaner (freeware edition), be sure to stick a firewall rule on the executable ? and take care in checking the options and tickboxes. This is another good option instead of ccleaner.

According to Piriform, PCs with the compromised versions would transmit the computer's name, IP address, a list of installed software, a list of active software, and list of network adapters to a third-party server located in the US. The company describes this as "non-sensitive data" which was used to profile affected PCs.

After collecting the data, the malware downloaded a second stage payload from the third-party server. As the payload was encrypted, Piriform hasn't explained what it's functionality is, however notes that it has not seen this payload being executed and believes its activation is highly unlikely.

Piriform says Avast detected suspicious activity on its download server a day ahead Cisco's notification, but hadn't warned the public until today due to its cooperation with US law enforcement, which involved shutting down the affected server on September 15.

"Working with US law enforcement, we caused this server to be shut down on the 15th of September before any known harm was done. It would have been an impediment to the law enforcement agency's investigation to have gone public with this before the server was disabled and we completed our initial assessment," the company said in a statement.

According to different reports, the malware is capable of collecting specific data from an infected computer system, including IP addresses and information on installed and active software, and sending it to a third-party server located in the United States. ff782bc1db
