Re: PATCHED Avast Antivirus 4.8.1368 [PC ~ ITA ENG]

By default, all vendors, software applications, and severities will be patched unless you exclude them. The Ignored Patches section displays vendors, applications, and patch severities on the exclusions list, which will not be updated. These settings will override Auto-Approval Rules.
A patch is a utility that can be used to change a few bytes in the original file. It's usually used to bypass license validation or to enable a hidden function. These patches are normally used with the knowledge and agreement of the user. However, another group of patches is actually malware which is used to perform the same functions without the user's knowledge or agreement. In this case, system files are patched to gain backdoor access to a system (i.e. by changing the startup key to run the malware after booting). These files are detected by avast! as Win32:Patched.
The bad guys always target their patch to system files. The system file user32.dll is the most often patched file. By patching just one byte, the intended malware can be run automatically after starting windows.

Avast Business Patch Management replaces your current collection of individual updaters with a single straightforward platform, delivered as an add-on to any of Avast's managed antivirus products (Antivirus, Antivirus Pro, Antivirus Pro Plus).
If you just want to try out Business Patch Management on a system equipped with another antivirus, that's unlikely to be a problem. Avast's installer is smarter than most, and can set itself up to run in a maximum-compatibility 'passive mode' if it detects another antivirus product. We tried installing the product on a Windows 10 system with Kaspersky antivirus already present, and had no problems at all.
Mike is a lead security reviewer at Future, where he stress-tests VPNs, antivirus and more to find out which services are sure to keep you safe, and which are best avoided. Mike began his career as a lead software developer in the engineering world, where his creations were used by big-name companies from Rolls Royce to British Nuclear Fuels and British Aerospace. The early PC viruses caught Mike's attention, and he developed an interest in analyzing malware, and learning the low-level technical details of how Windows and network security work under the hood.
After launching the game, it loaded like normal, i got ingame, alt-tabbed, and the game got shutdown, and got a Avast antivirus warning, the game's exe got moved to avasts virus safe, so now i can't run the game, now what?

The Advanced Local Procedure Call elevation of privilege vulnerability, tracked as CVE-2023-21674, was one of 98 flaws included in January's Patch Tuesday and could allow an attacker to gain system privileges. While Microsoft released a fix, which was first discovered by antivirus vendor Avast, it is listed as "exploitation detected" under the tech giant's vulnerability guide.
"We observed an active exploitation of the vulnerability and also can say that the vulnerability is likely part of a longer infection chain through [a] browser. Because for the CVE-2023-21674 exploit to work, the attackers already had to somehow obtain the ability to run arbitrary native code inside a sandboxed renderer process," Vojtěšek said in an email to TechTarget Editorial. "This is something that is normally not possible against a fully patched browser unless the attackers possess a separate rendered 0-day exploit."
The most recent Windows patch, released April 9, seems to have done something (still to be determined) that's causing problems with anti-malware software. Over the last few days, Microsoft has been adding more and more antivirus scanners to its list of known issues. As of publication time, client-side antivirus software from Sophos, Avira, ArcaBit, Avast, and most recently McAfee are all showing problems with the patch.
Booting into safe mode is unaffected, and the current advice is to use this method to disable the antivirus applications and allow the machines to boot normally. Sophos additionally reports that adding the antivirus software's own directory to the list of excluded locations also serves as a fix, which is a little strange.
Microsoft is currently blocking the update for Sophos, Avira, and ArcaBit users, with McAfee still under investigation. ArcaBit and Avast have published updates that address the problem. Avast recommends leaving systems at the login screen for about 15 minutes and then rebooting; the antivirus software should then update itself automatically in the background.
Avast and McAfee also provide a hint at the root cause: it appears that Microsoft has made a change to CSRSS ("client/server runtime subsystem"), a core component of Windows that coordinates and manages Win32 applications. This is reportedly making the antivirus software deadlock. The antivirus applications are trying to get access to some resource, but they're blocked from doing so because they have already taken exclusive access to the resource.
Given that patches have appeared from antivirus vendors rather than an update from Microsoft, it suggests (though does not guarantee) that whatever change Microsoft made to CSRSS is revealing latent bugs in the antivirus software. On the other hand, it's possible that CSRSS is now doing something that Microsoft previously promised wouldn't happen.
Every time your system boots up, various applications launch at startup. This is a feature used by many apps that you might want to have ready from the moment you gain access to your computer, such as antivirus software. However, many apps are not necessary for your device to load upon startup.
You can view patch deployment status and apply filters to fine-tune the information while a drop-down menu for each patch allows you to force deployment, ignore it or roll it back on a specific endpoint. Avast provides a set of graphical reports so you can check on patch deployments, see systems that have failed tasks or missing patches and check on patched applications.
However, it isn't a smart move tying BPM in with Avast's antivirus products as this could easily double acquisition costs. Businesses that like the look of BPM but already have a preferred AV vendor other than Avast will need to wait until it is available as a standalone product.
Avast Business Antivirus Pro Plus starts at $174.96 for five devices per yea. That price tag wraps the popular consumer desktop antivirus and security engine in a hosted endpoint protection package attractive to small businesses, since it's delivered as an easy to deploy and manage Software as a Service (SaaS) platform. While it's well-featured overall, we were disappointed to discover that just as when we tested it last year, the product still focuses entirely on Windows and Mac desktops, completely avoiding mobile devices. While it has added some nice ancillary capabilities, including a VPN service, a sandbox browser, and data shredder. its lack of mobile support and some weaknesses in reporting keep it behind our Editors' Choice winners, Bitdefender GravityZone Ultra, ESET Endpoint Protection, and Sophos Intercept X.
Avast has a solid, though slightly basic set of management features. For organizational benefit, devices can also be grouped together with settings templates. You can use the default settings templates here or build a custom template by traveling to the Device Settings page. Default template configuration is good for general use partially because it enables Avast's DeepScreen feature, which is how Avast knows how to deal with unknown files. The only opportunity to make the antivirus engine more aggressive is to activate a Hardened Mode. If Avast begins to report false positives for specific file paths or URLs (Uniform Resource Locators). administrators can add these to an exclusion white list. For testing purposes, we used the most aggressive settings.
As mentioned above, the most notable new feature is the ability to check for missing software patches on each endpoint. Patching has long been a struggle for smaller businesses that usually requires a separate tool entirely, especially for security-critical patches like those from Microsoft. While Microsoft, in particular, has gone a long way towards ensuring that its Windows 10 operating system will catch most unpatched systems, some still slip through the cracks. Avast gives admins a nice user interface to review unapplied patches and apply them on the spot, thereby cutting down on potential vulnerabilities.
