How to Uninstall Avast Free Antivirus?

Issue: Hello, all. After upgrading my PC to Windows 10 OS, Avast just stopped working. I tried reinstalling it, but that did not help so I gave up uninstalling it. The problem is that I can’t uninstall it via Apps & Features as it tells me that the “Avastip.dll not found.” Could you please help me to sort this out?

Solved Answer

Avast Free Antivirus is a security utility developed by the security giant Avast. The company holds the biggest share of the world market for anti-virus apps and supplies a wide range of security-related products for both consumers and corporations (Android, Microsoft Windows, iOS and macOS).

Based on the statistics conducted in 2016, Avast had 400 million users and held 40 percent of security software market outside China. In 2017, the company acquired Piriform,[1] the company which developed and managed CCleaner tool. The latter became infamous after hackers compromised CCleaner[2] 5.33.6162 and CCleaner Cloud 1.07.3191 versions in September, 2017 and pushed millions of its users into a risk of getting Floxif malware.

Naturally, device users who tried Avast share various opinions regarding the tool. Nevertheless, based on independent testing at third-party laboratories, it features a high ability to block, detect and remove viruses. It adds a network security scanner, provides a password manager, offers to secure web browser and its toolbar (Google Chrome) and other useful features.

It is able to detect and block adware and keyloggers in particular. The analysts at AV-Comparatives[3] performed a security test and provided two Advanced+ and two Advanced ratings, meaning that the product is much higher than a Standard rating tools.

However, Avast often fells down in the performance category and can negatively influence device’s performance when scanning for malware. Some people disapprove of this security tool because it doesn’t include parental control.

In a nutshell, Avast is a great tool for protecting your PC, but not the best. Usually, it can be removed via Programs and Features or Apps & Features on Windows, but after the release of Windows 10 Fall Creators Update many people reported that Avast stopped working and can neither be re-installed nor removed.

According to users, the removal process fails with an error indicating a missing Avast files (e.g. Avastip.dll, avast.messaging.dll) as the culprit. If you opt for Avast removal due to one or another reason but the removal fails, we will explain what steps have to be taken to eliminate the tool successfully.
