Google has been on a silent crusade since August 2014 against websites contain unsolicited software or malware (or, as some AV vendors call them, potentially unwanted applications), as defined in this Google policy. Most unwanted software comfoulage their software into posing as a helpful download but ultimately these kind of softwares make changes to the users’ browser and its settings. Such changes that are profitable to the software’s creators but are a nuisance users. In fact, they could ultimately harm the user. These unwanted software than hire ad agencies to push for the downloads through advertising on websites. The ad agencies more often than not do not vet these softwares thus putting users at grave risk. Google has been making changes to its Safe Browsing web service, which serves to warn Chrome, but also Safari and Firefox users, about unsafe websites. The service uses a continually updated blacklist of unsafe sites, against which each requested site is checked before being loaded by the browsers. Moheeb Abu Rajab and Stephan Somogy, from the Google Safe Browsing Team, have announced that in the coming weeks, the Safe Browsing service will start showing more warnings about unwanted software than usual. So next time you see a warning in your Google Chrome, you know Google Safe Browsing is doing its work very efficiently.
