This article aims to help users remove Ads by KeyStream Virus from Chrome, Firefox, Internet Explorer and Safari, as well as their respective system.
Ads by KeyStream Virus is a type of rapid spreading malicious software, the kind of which is known as Adware in the anti-virus communities. The name is closely related to the main function of the virus – to create large amounts of advertisements and to display them in your browser without permission. Ads by KeyStream Virus does not have a pause button and cannot be turned off – the only way to stop the annoying Ads is to delete it from your machine and this could be a tricky business. Don’t worry – we’ll help.
What is important to realize is that while Ads by KeyStream Virus is certainly malicious it lacks the capability to hard your computer directly. Instead it works like a backdoor for other viruses and scam software. Thus it is very important NEVER to download anything that Ads by KeyStream Virus may offer you or click on the links that come with the Ads.
Be wary of Ads that appear as system messages
As part of the deception campaign that Ads by KeyStream Virus launches against you it is possible to see a large variety of warning that try to look as if they are generated from your own computer. Examples include messages about missing plug-ins, about required codecs and video players. You could also receive “free online scans” that have detected “many problems” with your computer – usually viruses or maybe errors in the registry. You are then offered to download the missing program or install a utility program that can fix the problem for free.
Do not trust any of this! As explained none of the problems are real and the programs you are offered to download are nothing but viruses or bloatware.
The links of Ads by KeyStream Virus are also not safe. There is a very good chance they will take you to cloned sites of real online shops where your account name and password will be recorded when you try to log in. Afterwards the hackers will access them and use them to log-in to the real site, steal your credit card numbers and make purchases in your name.
