How to remove YAC (Virus Removal Guide)


Yet Another Cleaner (YAC virus)

YAC virus (Yet Another Cleaner virus) is a malicious and fraudulent Windows optimization and security program that is detected as a ‘fraud tool’ for stealing a competitors database and scareware by reputable Anti-Malware products. The rogue program is offered as an unregistered (free) and registered (full) Microsoft Windows cleaner and optimizer tool. YAC is essentially considered a non-beneficial Windows Optimizer and Antivirus by reputable security experts. The program is known to perform fraudulent computer scans in order to create customers and collect personal user information.

Once the YAC program is installed it will begin to perform a scan without user authorization. When the scan is over the results will state that there are problems detected that are not safe; However, the results shown are usually fake and completely fabricated by the developers or stolen from another programs database.

The YAC virus also launches internet browser windows at random and will cause unwanted pop-ups to appear inside your browser window and on Windows desktop. The program will also change your homepage and default search engine which will cause your affected internet browsers to constantly start up on and redirect to search.yac.mx when you search the web, open a browser window, or open a new browser tab. In Google Chrome, the YAC virus hijacks your homepage, removes the homepage button, and changes the default search engine to a new one.

Yet Another Cleaner is usually downloaded and installed without user knowledge. It is known to download and install alongside free downloadable content from a variety of locations on the web including freeware, shareware, torrents, email attachments, dubious software updates, and more. To make matters worse, the program might also be advertised by malware, adware, and malicious websites that also advertise third-party threats.

Those who wish to install freeware may be given a “custom installation” option to accept or decline an offer to install Yet Another Cleaner adware and similar products during the installation; However, the user request to decline the unwanted program from installing can be ignored by the program or presented in a confusing manner.
