What is Comcast.net virus?

Comcast.net virus is a term used to describe a malware that lures gullible Comcast Xfinity users into malicious websites. Comcast is an American global telecommunications conglomerate and is the largest broadcasting and cable TV company all over the globe. Comcast’s official website is at Xfinity.com. Recently, there have been reports from the company’s clients regarding Comcast’s search engine which is at xfinity.comcast.net. According to clients, each time they used the search engine, they are redirected to suspicious domains that triggers dozen of ads in their new tabs. Some of the users even claimed that they completely lost control of their PCs and that they had to restart it to temporarily fix the problem.

Before all these fiasco, Comcast.net, which now redirects to Xfinity.com, is a useful website that lets users sign up for different services and allows them to create an email account, sign up for DVR Manager, Home and Security Control, Constant Guard and other services. Aside from that, it also displays information regarding latest happenings, videos, weather forecasts and other interesting things for its users. Security experts deemed this website to be safe and have nothing in common with viruses and whatsoever. However, security experts are also considering including Comcast.net under the list of potentially unwanted programs as it collects information about its users which may even be shared with third parties. Adding up to the reasons is the latest issue wherein Comcast.net redirects users to suspicious domains that causes ads.

Several malware analysts have reported that before, the Xfinity search engine was serving a malicious ad in its search results and when users click on that particular ad, it redirected them to Sattvpro.com review website that also causes many browser redirects which had lead several users to a compromised website hosting Nuclear exploit kit. This exploit kit is a set of malicious scripts used in distributing ransomware infection called CryptoWall. And if you think that’s the worst thing that it could get, you’re wrong – aside from promoting the exploit kit, the malvertising campaign also promoted a phishing website which urges users to call tech support scammers. The deceptive web page tells users that “Comcast’s security plugin has detected some suspicious activity from your IP address” and then it suggests calling a tech support toll free number for further assistance.

In conclusion, Comcast.net is a legitimate website, however, cyber crooks have been using this giant company’s name in malvertising campaigns that cause several problems for many users. Although some of the ads are legitimate, most of them are suspicious and can’t be trusted making it really hard to identify which ones are safe.
