What is Vigua.A virus
Vigua.A virus refers to a generic detection name used by Windows Defender to detect potentially unwanted programs (PUPs). When Windows Defender is active on the computer, if a PUP it detects is installed on your computer, you will see a notification that PUA:Win32/Vigua.A has been detected. PUPs are not serious infection and you should not be too alarmed. They’re more like legitimate programs that have questionable features which anti-virus programs pick up on.
There are many different PUPs out there, from questionable system optimizers to outright adware. They usually share one common characteristic, installation via software bundling. We will explain in more detail later on, but those programs can install without needing explicit permission and without even noticing. Even if the program is legitimate, anti-virus programs may classify it as a PUP if it uses this questionable installation method.
PUPs are usually not dangerous, though they are very annoying. Depending on the PUP’s type, one may make unwanted browser’s setting changes, another may redirect to questionable websites and show more ads. One could also pretend to be a useful programs, such as a system optimizer. Some PUPs are not recommended to keep, while others may actually be somewhat useful to users. Check which program is detected exactly and research it if you don’t recognize it. You can choose to allow Windows Defender to delete Vigua.A virus.
How does a PUP install
If you have a potentially unwanted program installed on your computer, you are likely not aware that free programs come with additional offers. The PUP was probably attached to a free program you installed as an extra offer, and you did notice. The extra offers are set to install alongside freeware automatically, unless they’re manually deselected by users during installation. But because the offers are hidden, many users simply do not notice them when installing free programs.
To be able to prevent added offers from installing alongside freeware, you need to pay attention to how you install those programs. Most importantly, you need to opt for Advanced (Custom) settings instead of Default. Advanced will make all added offers visible, and you will be given the option of deselecting them. Simply unchecking the boxes is enough to prevent their installation.
It’s also possible you installed the PUP yourself intentionally. There are many potentially unwanted programs advertised as useful ones, and users often do not research programs before installing them. You should always look into programs before installing them, even if it’s a simple search with Google. This, and paying attention to how you install programs will help keep the computer free of junk.
Is Vigua.A virus dangerous
There are many different types of PUPs, some may hijack your browser, while others pretend to be useful programs. Browser hijackers and adware are one of the more common infections of this kind. Browser hijackers take over browsers and change their settings in order to be able to redirect users to sponsored content. They also modify search results and force users to use questionable search engines. Adware generates pop-ups and causes redirects, in addition to showing regular ads.
PUPs are also often disguised as useful programs, such as anti-virus or system optimizers. The programs are made to seem useful so users install/keep them, but actually have other motives. They either expose users to many ads, try to convince users to buy the full programs, or spy on them. Rogue anti-virus and system optimizers falsely claim that there is something wrong with the computer and then offer to fix the issue if users buy the full version of the program.
PUP are generally harmless by themselves. Though it’s difficult to tell which PUP is inhabiting your computer as PUA:Win32/Vigua.A is a very generic detection name. You need to check the details of the alert to see what exactly is the issue. You can then decide whether you will remove Vigua.A virus or allow it to stay.
