Yesterday my security program scanned the system and detected a threat. It is called Krab Web. I keep getting a lot of pop-up ads when I start my computer, so I cannot go on my work as usual in the computer. I do not know how this advertising software gets into my compute. Anyway, is there a good way to get rid of Krab Web when the antivirus program is unable to remove it for some reasons?
Krab Web is a useless adware that will weaken the computer performance and help another malware to get into the computer. It can also be seen as a browser hijacker for it is able to take over the browser on the computer so as to show you many pop-up ads. Some malware, spyware and even Trojan viruses will make use of the vulnerabilities caused by the adware to access the target users furtively. Usually, Krab Web enters the computer system through hiding in some free software from unknown sources, suspicious shared files, hacked web sites and spam emails. If it gets the chance to install on the target computer, it has the ability to change Windows host files as well as browser settings so that it can show you unreliable commercial ads at any time. In addition to that, the adware can also track the online activities of the computer user.
If the Krab Web adware stays in the computer for a long time, it will gradually expand infection, because it needs to create a good environment for itself to live safely and then perform the tasks set by its developers. It is capable of analyzing your computer system database. Therefore, your personal information in the infected computer may be disclosed while you know nothing. Your recent online activities and search keywords will be recorded. If you are not able to get rid of the Krab Web adware as soon as possible, you may have to face the risk that an unknown third party steals your private data without letting you know. To remove this Krab Web adware completely, you should take manual removal method instead of running antivirus software because it has the ability to bypass most of antivirus tools.
