This article contains instructions on locating your Avast order number (sometimes called an Order ID or a reference ID number) if requested by Avast Support for troubleshooting or identification purposes.
You can find your Avast order number in the order confirmation email that you received after completing the purchase. Avast has partnered with established eCommerce providers that manage online sales and distribution in certain regions. The exact location of the order number varies according to the distributor.
There are no known Viruses in the wild that self replicate and affect macOS. There are Malware and Adware that does affect macOS and are often times downloaded as part of an Application from Third Party UnTrusted Site and get installed along with the Application. And for that instance - Suggest downloading from a Trusted Developer and Respected ASC Contributor the application Malwarebytes for Mac. It is free or paid for added features. Run the Application and it should remove the malware / adware. Once done, restart computer and test.
You can check to see if you've removed all of the supporting files by downloading and running the shareware app Find Any File to search for any files with the application's or the developer's name in the file name. For Avast software you'd do the following search(es):
You really should remove Avast completely. Try re-downloading Avast and running the installer, in the past they had an option in the installer to uninstall it. It's been a while since I encountered Avast. But you could also try re-installing it and then following the support document to uninstall it.
Falling that, Suggest downloading the Application Etrecheck directly from a Trusted Developer and well Respected ASC Contributor. The application is free or paid from added features. Run the application with Full Disc Access ( Security & Privacy - Full Disc Access ). It will take a Snap Shot - both the hardware and software. The Report will Not Reveal Any Personal Information. Post back the Full Report - copy and paste - using the Additional Text Icon ( 3rd Icon to last )
@p.phillips thank you. I downloaded (and paid for) Find Any File and completely eliminated any file with "avast" in it. Although I am carefukl to always use AppDelete to get rid of apps, for some reason the Avast app was not onmy machine, but thousands of support files were (now past tense). Thanks for the tip. James
Avast keeps going off and popping up saying C:\...\Update.exe has been blocked but doesn't give me any more information. How do I find out what file is being detected and what connection is being blocked? Under the "antivirus" there isn't even a section for logs and under "firewall" I go to logs but there aren't any log entries for today.
Main problem with the updaters : They can download files in your computer and install automatically without your permission if you have left the Update automatically option during the installation of the software. If a Trojan program is installed in your system, then it is no longer called "your system" in the security circle.
It is important to pay attention to this issue or else your web browser might get affected. Then there will be a lot of stuff will happen to your browser (like unknown add-ons, tool bars, unwanted ads,etc.,) and your AV will detect even the normal websites you visit as harmful once your browser is infected.
Now all you have to do is just to confirm whether the detected Updater.exe is harmful and carry on with the removal process(I found Remove URL:Mal and Removal Mal articles that gives a walk through on the removal of URL:Mal infectors). If you are not sure about the existence of such malwares in your system there are plenty of ways to sweep them off using a good anti-malware with an updated anti-virus software.
I've encountered a similar problem with other antivirus software. It's aggravating when antivirus software reports a problem with a file but displays "..." or something similar as part of the directory path and lacks an easy way to see the full directory path, especially when there may be many files with the name noted on the system. The developers of such antivirus software often seem to assume that the users of their product are technically unsophisticated and so just want to click on a "remove" button. Such alerts should at least be logged in a file by an entry containing the full path and file name with the log file easily viewed by a user.
To resolve the problem you could install additional anti-malware software and scan the system with it. I've found Malwarebytes Anti-Malware works well with antivirus software from other vendors. You can download the free version and scan the system with it. It may also flag a updater.exe file. Alternatively, you could search the system for every updater.exe file and upload them one by one to VirusTotal, a site now owned by Google that will scan files you upload with many antivirus programs and display a report letting you know how many of them detected a file as malware and the name assigned by each to the malware, if they identify the file as being associated with malware. Other sites that will also scan an uploaded file with multiple antivirus programs:
Avast Software s.r.o. is a Czech multinational cybersecurity software company headquartered in Prague, Czech Republic, that researches and develops computer security software, machine learning, and artificial intelligence. Avast has more than 435 million monthly active users[2] and the second largest market share among anti-malware application vendors worldwide as of April 2020.[3] The company has approximately 1,700 employees across its 25 offices worldwide.[2] In July 2021, NortonLifeLock, an American cybersecurity company, announced that it was in talks to merge with Avast Software. In August 2021, Avast's board of directors agreed to an offer of US$8 billion.[4][5]
Avast was founded by Pavel Baudiš and Eduard Kučera in 1988 as a cooperative. It had been a private company since 2010 and had its IPO in May 2018. In July 2016, Avast acquired competitor AVG Technologies for $1.3 billion. At the time, AVG was the third-ranked antivirus product.[6] It was dual-listed on the Prague Stock Exchange and on the London Stock Exchange and was a constituent of the FTSE 100 Index until it was acquired by NortonLifeLock in September 2022.[7]
Avast was founded by Eduard Kučera and Pavel Baudiš in 1988.[8] The founders met each other at the Research Institute for Mathematical Machines in Czechoslovakia.[8] They studied math and computer science, because the Communist Party of Czechoslovakia would require them to join the communist party to study physics.[8] At the institute, Pavel Baudiš discovered the Vienna virus on a floppy disk and developed the first program to remove it.[8][9][10] Afterwards, he asked Eduard Kučera to join him in cofounding Avast as a cooperative.[9] The cooperative was originally called Alwil and only the software was named Avast.[11]
The cooperative was changed to a joint partnership in 1991, two years after the velvet revolution[12] caused a regime change in Czechoslovakia. The new regime severed ties with the Soviet Union and reverted the country's economic system to a market economy.[9][11] In 1995, Avast employee Ondřej Vlček [cs] wrote the first antivirus program for the Windows 95 operating system.[9] In the 1990s, security researchers at the Virus Bulletin, an IT security testing organization, gave the Avast software an award in every category tested, increasing the popularity of the software.[9] However, by the late 1990s, the company was struggling financially.[8] Alwil rebuffed acquisition offers by McAfee, who was licensing the Avast antivirus engine.[8]
By 2001, Alwil was experiencing financial difficulties, when it converted to a freemium model, offering a base Avast software product at no cost.[9] As a result of the freemium model, the number of users of the software grew to one million by 2004[9] and 20 million by 2006.[11] Former Symantec executive Vince Steckler was appointed CEO of Avast in 2009.[13] In 2010, Alwil changed its name to Avast, adopting the name of the software,[11] and raised $100 million in venture capital investments.[14] The following December, Avast filed for an initial public offering, but withdrew its application the following July, citing changes in market conditions.[15] In 2012, Avast fired its outsourced tech support service iYogi, after it was discovered that iYogi was using misleading sales tactics to persuade customers to buy unnecessary services.[16] By 2013, Avast had 200 million users in 38 countries and had been translated into 43 languages.[8] At the time, the company had 350 employees.[17]
In 2014, CVC Capital bought an interest in Avast for an undisclosed sum. The purchase valued Avast at $1 billion.[18][19] Later that year, Avast acquired mobile app developer Inmite in order to build Avast's mobile apps.[20] Additionally, Avast's online support forum was compromised in 2014, exposing 400,000 names, passwords and email addresses.[21][22] By 2015, Avast had the largest share of the market for antivirus software.[15] In July 2016, Avast reached an agreement to buy AVG for $1.3 billion.[23] AVG was a large IT security company that sold software for desktops and mobile devices.[24] In July 2017, Avast acquired UK-based Piriform for an undisclosed sum. Piriform was the developer of CCleaner.[25] Shortly afterwards it was disclosed that someone may have created a malicious version of CCleaner with a backdoor for hackers.[26] Avast had its IPO on the London Stock Exchange in May 2018, which valued it at 2.4bn and was one of the UK's biggest technology listings.[27]
Ondřej Vlček [cs] assumed the role of CEO and co-owner of Avast Plc in July 2019.[28] A day later, he changed his annual pay to $1 and pledged his board director's compensation of $100,000 to charity.[28] In October 2019, Jaya Baloo joined Avast as their Chief Information Security Officer.[29]
