To say the least, the Web App Extension by lpsafecheck.com is unwanted. This plugin is brought to you by a nasty cyber infection and has nothing but trouble to offer. Hence, you have to locate and then uninstall a parasite. Luckily, the virus is classified as a potentially unwanted program (PUP) or adware. In other words, you’re stuck with a relatively easy to tackle sort of parasite. Your situation could have been a lot worse as the Internet is filled with Trojans and ransomware. Even though there are more destructive types of malware out there, no virus is to be overlooked. Keeping the adware/PUP on your machine would allow the parasite to get out of hand.

It injects your browsers with sponsored pop-ups and causes quite the mess. For starters, the plugin gets added completely behind your back. We assume you wouldn’t appreciate having your favorite settings changed without your permission. Furthermore, all modifications made by the virus put you in danger. Hackers develop cyber intruders for one very simple reason. They are aiming for revenue which means you’re currently a sponsor of crooks. You might be interested to know the ads generated by this pest are all sponsored. And, clicking a sponsored commercial open would certainly not be a smart move. Keep in mind that the PUP/adware covers your PC screen with ads in order to trick you into clicking. We’re talking pop-ups, pop-under ads, banner ads, interstitial ads, video ads. Get yourself prepared to be seeing irritating commercials on a daily basis. As mentioned, the parasite modifies your browser settings and effectively destroys your online experience. What’s even more worrisome is that these sponsored ads don’t necessarily have to be harmless. Quite the opposite. Some of them could turn out to be fake and extremely dangerous. Clicking them would lead you to dubious websites filled with malware. Thus, you could easily compromise your safety further with one single careless click. Make sure no more infections land on your device and avoid the ads. As if flooding your PC screen with commercials wasn’t enough, the virus also jeopardizes your privacy. It spies on your private information such as browsing history, usernames, passwords, email addresses. Your IP addresses get monitored too. Long story short, the adware/PUP must be deleted for good.

How did I get infected with?

The virus was probably bundled with other programs. This seems to be hackers’ favorite method to spread infections online. After all, it is an effective technique which allows the virus to land on board in silence. Unless you keep an eye out for potential intruders, you might accidentally compromise your security. To prevent that, always opt for the Custom or Advanced option in the Setup Wizard. Take your time during the installation process instead of rushing. You might download a whole bunch of viruses via one single freeware or shareware bundle. There is a reason why crooks prefer this tactic over the others. Many PC users skip installation steps and end up downloading malware themselves. To avoid that, make sure you’re aware of the programs you’re giving green light to. Checking out the Terms and Conditions or EULA (End User License Agreement) is another rule of thumb. In addition, stay away from unverified bundles even if they appear to be perfectly harmless. It takes one single moment of distraction to install a vicious infection. Deleting the intruder, on the other hand, would take much more.
