How Did I Install DNSAdlocker?
One way to get affected by this bad chunk of code is by clicking on online advertisements that may initiate a download of such software that is being advertised as a useful tool of some sort. Another way to get affected by it is by downloading programs like torrent engines, media players, file converters and others from free software providing sites. This can happen if the site providing the free software decides to include PUPs, like DNSAdlocker as free ‘extras’ in the installer program. It is otherwise known as bundling, and it is a very effective method of massive software distribution over the web. It is also a profitable marketing service, and this is why many third-party services prefer it.
DNSAdlocker in Detail
Similar to DNS Unlocker, DNS Unblocker and DNS Keeper, once installed on your computer, this malicious program may run as an active .exe application on your computer and slow it down. Some affected users also believe that they have experienced internet connection problems with their computers, mainly related to their DNS settings. More to it than that, this software may employ tracking technologies on your computer, such as:
- Browsing cookies.
- Session cookies.
- Web beacons.
- Flash Cookies (Or Local Shared Objects).
Those technologies could track the user’s online clicks, website visits, and bookmarks with the one and only purpose of implementing behavioral advertising. This means that they may display targeted ads based on the user’s searches. Usually, the advertisements displayed are two types:
- Some may display ads, based on what the user searches most in general on the internet from the beginning of time.
- Some may display advertisements based on the moment i.e. if a user searches for something or visits something the ads may pop-up instantly on that subject.
More to it than that, the sole generating and the displaying of advertisements by DNSAdlocker may in some cases cause PC slowdowns. This is because it generally consumes a lot of random access memory(RAM) and processing power (CPU).
The main reason these ads are dangerous, however, is the detail that they often redirect the user to third-party websites. Since most adware developers do not mind as to what it is they advertise, they often promote suspicious sites. And some shady sites may conceal different dangers from the user:
- Malicious drive-by downloads that may infect the user’s computer with Malware (Viruses, Worms, Trojans, Scareware, etc.)
- Fake customer support toll-free scams that scare the user with different messages and make him conduct expensive phone calls.
- Subscribing of users to an expensive SMS service that drains money from their SIM cards.
- Scam users into filling out fake registration forms with their personal and financial information as a part of a fake prize claims or participation in surveys with a reward of some sort.
These are most likely not even half of the threats that are connected with online cyber-crime. They are constantly evolving, and this is why it is important to keep up to date with them all time.
