The names of the .exe file can be diverse, however, the impacts are almost always the identical. Because coin miners focus on cryptocurrency mining, they use all possible hardware power of your PC to perform this operation.

Presentationfontcache.exe – Extremely high CPU/GPU usage

Besides CPU consumption, some of the coin miners also utilize GPU power for their operations. In that instance, you will probably struggle even to see the mouse cursor moving – GPU is often used on 100%. It is not as critical as processor for system work, so Presentationfontcache.exe coin miner viruses don’t waste time on trifles and use all of it. It sometimes may result in unhappy results.

Shortly about cryptocurrency mining

Crypto mining means the operation of calculating the transaction block hash. That is a integral part of anything based on the blockchain technology. Since this action takes a lot of calculations, a high-end computer is needed. Exactly, the graphic card is better for this task, because they have more cores available. Cryptocurrency mining farms are usually constructed of dozens of GPUs to complete their task efficiently. Such computer systems are not usable for “usual” purposes, like gaming or browsing the Web. Crooks who make profit via this coin miner use someones’ PCs instead, even if they are used for the regular activity.2

All these changes shall be thrown back to the initial state in the process of PC recovery.

    Hardware effects of coin miner activity

    Besides making your PC slow, running at peak power for long times can trigger damage to your machine as well as increase electricity expenses. Hardware components are designed to easily get along with high load, but they are good with it only when they are in a good shape.

    Small and covered processor fan is not very easy to damage. Meanwhile, graphic cards have large and easy-to-access fans, which can be easily cracked if affected while spinning, for example, by the user much before the virus injection. Malfunctioning cooling system, together with the unusually high load caused by Presentationfontcache.exe miner can easily lead to GPU failure3. Video cards are also tend to have fast wearing when used for crypto mining. It is likely a bad situation when your GPU’s performance decreases on 20-30% just after several weeks of being exploited in such a way.

    How did I get Presentationfontcache.exe coin miner virus?

    Coin miners are spread through different ways, but their main sources are malicious banners and programs from dubious sources

    Coin miners are the most prevalent malevolent programs through “major” malware. Adware often functions as a carrier for Presentationfontcache.exe malware injection: it demonstrates you the banners, which have a link to malware downloading. Yes, this abstract “malware” can belong to any kind – an additional adware, spyware, rogue or backdoor. However, the statistics say that approximately 30% of all viruses spread through the malicious banners are coin miners – and Presentationfontcache.exe is right one of them.

    Unwanted banners adware

    The example of malicious banners you can see in the Internet

    An additional way you could get this item on your computer is by downloading it from the dubious website as a part of a program. People who spread hacked versions of popular programs (which do not demand the license key) have small chances to earn money. Hence, there is a very big lure to include malware to the final package of the hacked app and get a coin for each installation. Prior to blaming these people for hacking and also malware distribution, ask yourself – is it OK to avoid purchasing the program in this manner? It is more affordable to pay $20-$30 at once than to pay a much greater figure for antivirus program as well as new parts for your desktop.

    How to remove the Presentationfontcache.exe miner from my PC?

    The best way to get rid of this coin miner virus is to use anti-malware software

    Removing such a virus needs the use of special tool. Effective anti-malware program must have high capability at scanning and also be lightweight – in order to make no problems with usage also on weak systems. Additionally, it is better to have proactive security in your security solution – to stop the virus even before it launches. Microsoft Defender lacks these functions for different factors. That’s why I’d advise you to use a third-party anti-malware program for that purpose. GridinSoft Anti-Malware is a perfect choice that fits each of the specified features.4

    Prior to the virus removal, it is important to boot your system into Safe Mode with Networking. Since Presentationfontcache.exe miner consumes a lot of CPU capacity, it is needed to halt it before launching the security program.

    When your computer is in Safe Mode, all third-party programs, just like the majority of non-crucial operating system components, are not launched with the system start. That allows you to clean the computer without dealing with high processor usage of the coin miner.
