Fasst virus – an adware producing numerous pop-ups and slowing your browser in this way

Fasst virus
Fasst is an ad-supported program which provides numerous pop-ups and pop-unders.

Fasst virus is an adware-type program which infiltrates the system for the only aim – getting a chance to take over the web browser and filling it with the sponsored content. This program is considered as a PUP as it can add malicious extensions to victim's browsers without any permission asked, and alter bookmarks or similar settings just to redirect him/her to required sites to earn the money. Fasst virus produces numerous pop-ups and pop-unders which cannot be missed when having this virus on the system. Typically, its ads start popping up whenever you try to browse the web via the infected browser and can be eliminated only by removing the malicious extension related to this virus from the system.

Name Fasst virus
Type Adware
Danger level Medium. Affects web browsers and redirects its victims to sponsored content
Can be recognized by Continuous ads appearing on every browser which is affected by this virus
Browsers affected Chrome, Firefox, IE, Edge, etc.
Elimination process Use Reimage to delete adware from your computer.

You can recognize this adware on your system by looking at the text written in its ads. Typically, its ads are usually marked like this:

  • Ads by Fasst;
  • Brought to you by Fasst;
  • Powered by Fasst.

Once such ads pop-up, you should be worried as it is a clear sign showing that your PC is infected with the adware-type program. It might seem not that harmful at first, but it truly affects your browser in a negative way as it fills it with unwanted content and can easily slow it down or even crash it. As a result, your browsing sessions can become disturbed and may even end up with malware as such programs are typically used to promote highly suspicious domains.

Furthermore, various non-personal details can be gathered while having this PUP on your system. It can be explained quite easily as the developers of such programs typically need to see what kind of sites people like to visit, what ads they like the most, where are they living, what email address are they using, etc. Such information is typically collected to gain more income from personalized ads that rely on the marketing technique called pay-per-click. To outrun such annoying and sometimes even harmful activity, remove Fasst virus from your browser immediately. Try using Reimage anti-malware tool for this process as we cannot provide the exact name of this malware.

Keep in mind that adware-type programs are widespread and can easily infiltrate your system thru its backdoors. If you happen to overcome one of the previously-mentioned ads, you should think what freeware-type app have you recently downloaded to the system. Additionally, check your system with reliable software to take care of Fasst virus removal.

Stay clean from ad-supported software to prevent unwanted activity

It is not a secret that adware is produced with the help of other programs. Such a method is called “bundling”[1]. Adware-type programs come within bundled freeware and easily get into the computer system. Furthermore, dubious sites might also contain redirects to various harmful content. Some adware might even have their original downloading website.

To avoid hazardous actions against your PC, you need to learn some steps:

  1. According to IT professionals[2], it is always necessary to be careful while surfing the Net. People often lack cautiousness and get themselves in trouble while encountering suspicious sites. Stay away from pages you do not know. If you already entered such content – eliminate it immediately and never return.
  2. Download your software only from original downloading sources. Avoid using third-party downloaders as they cannot be trusted. Also, carefully look through all downloading/installing steps when you are doing a download/installation of a certain program.
  3. Install an antivirus. Professional protection is needed due to secure your system fully. This type of program will scan your system regularly if kept up-to-date[3].
