What is RelaySys?

RelaySys is a very questionable application that may seriously disrupt your web browsing activities. It may initiate irritating advertisements, redirect you to suspicious websites and even track your online activities. We have found out that this dubious app is usually introduced to people as a handy tool that may improve their browsing experience by informing them about the latest deals, discounts, and similar things. However, after making a small research on it, our security experts have found out various downsides that RelaySys virus has. First of all, it’s important to mention that it is sponsored by third parties and has one main purpose – to make people visit predetermined websites. Secondly, this dubious browser add-on may invoke tracking software (‘cookies’) and continuously record what websites do you visit, what data do you enter in them, what search terms you type and so on. Of course, RelaySys itself is not targeted at collecting your log-ins, passwords, and other sensitive information. Unfortunately, bearing in mind that it’s closely related to third-parties, you can never be sure that they will not decide to take some pieces of personally identifiable information. By the way, you should be very careful with RelaySys ads, as they can be filled with links to questionable or really suspicious third-party websites. As you probably already know, websites that are monitored by third parties may be filled with suspicious content. Therefore, you should try to prevent RelaySys redirects in advance. For that, we recommend using Reimage or another reputable anti-spyware.

How can RelaySys hijack my computer?

RelaySysis spreads as a browser add-on and can smoothly work on all the most popular web browsers, including Google Chrome, Mozilla Firefox, Internet Explorer and Safari. Unfortunately, people are usually not very happy about smooth work of this program on their web browsers since that ‘smooth work’ means that it may initiate tons of sponsored advertisements, use your computer’s resources, diminish web browser’s performance, initiate unwanted redirects and so on. Even more, all these inconveniences may begin out of nowhere. Usually, people start suspecting that their computers have been affected by a suspicious program when they notice suspicious messages marked as ‘Ads by RelaySys’ or ‘Powered by RelaySys’. Fortunately, it’s quite easy to prevent infiltration of such and similar programs. For that, you just have to take your time and never rush during installation of free programs. By the way, you should remember one important thing. Quick or Basic installation may be set not to disclose ‘additional components’ and install them automatically. Bearing this in mind, you should always opt for Advanced or Custom installation option and look for the list of ‘optional downloads’. As soon as you detect suspicious add-ons, plug-ins, toolbars, or extensions marked by default, make sure that you unmark ticks notifying your agreement to install them. Have you already installed RelaySys virus? Then follow the guide below, but please be more careful in the future.
