Also, it can be downloaded from multiple official sources, such as Google Play or Microsoft Store. Additionally, UC Browser is widely used in Asia and is the third most-used mobile web browser. Nevertheless, some users and security expressed concerns about the privacy issues that are related to the app, as it uses weak encryption to store data and also might be transferring personal information to third-parties.

The search tool is promoted as the engine which meets even the pickiest users’ demands: fast and secure and an ad-free experience. The search tool operates in Chrome, Internet Explorer, and Opera browser.

However, there have been multiple complaints about this browser which led users call this browser a Chinese UC Browser virus. Let us look through the cases thoroughly and discuss ways how to remove UC browser virus.

The browser was launched in April 2004. However, though quite a while has passed, complaints have not ceased. In 2016, the very browser was flagged as a trojan.Agent.lwrp[4]. Security specialists have considered it as a false positive.

Additionally, a thorough analysis by Citizen Lab disclosed that the browser is not save and uses weak encryption:[5]

Our analysis finds that all versions of the browser examined, both Windows and Android, transmit personal user data with easily decryptable encryption. In addition, the Windows version of the application does not properly secure its software update process, leaving it vulnerable to arbitrary code execution.

Furthermore, the Ministry of Electronics and Information Technology (MEITY) in India was investigating the breach that allegedly sent private information of Indian users to Chinese servers, as well as left devices with altered DNS settings after UC Browser removal.

Promoted in the phishing site

Now, neither UC browser official site nor the installer is labeled as malicious[6]. Nonetheless, reports about this browser being a virus are still quite new. Bothersome ads have been redirecting users to the phishing site which attempts to deceive users that their device is infected with malware.

This scam was mainly spotted in Opera Mini browser designed for mobile devices. The message says that “your Opera Mini is heavily damaged by (5) viruses.” The message urges victims to switch to UC Browser to prevent further damage on the SIM card[7]. However, such reports are simply scareware.

In response to these claims, the representative of International UC Browser company stated dishonest marketing publishers were at fault for using such techniques to direct traffic to UCWeb products. He also added that the company will tackle the issue.

On the other hand, such statement does not provide necessary answers to the questions. What is be the point of directing the traffic to UC Browsers without gaining profit? It is very unlikely that the marketers receive the profit from other than the main distributor.

Dubious privacy policy provisions

The very privacy policy of UC browser only fortifies the assumptions about dubious promotion techniques. It mentions that no private data is shared without users’ consent. On the other hand, they mention that:

We may share your personal information, which may include your name and contact information (including email address) with third parties that perform certain services on our behalf. These services may include providing support, performing data analysis, and providing and supporting Site functionality and features.

Though the UC browser developers claim that these providers are obliged not to use the acquired information other than for service providing purposes, the above-discussed sample of the phishing site suggests that the developers failed at surveying them properly.

Further paragraphs mention that the collected non-personal information which includes browsing history, search entries, IP address and other related data, might be shared with the service providers. As a result, more personalized ads might distract you during browsing sessions and if such phenomenon bothers you, you might start thinking how to remove Chinese UC browser.
