removal by Jake Doevan - - | Type: Adware

Description of Sec-slihf.com virus

If you haven’t heard this yet, nowadays fake tech support scammers spread dubious adware programs to advertise their phone numbers. Typically, these adware programs deliver pop-up alerts in new browser tabs or open new windows. Sec-slihf.com adware displays misleading messages that claim user’s computer is infected with spyware or malware, and the only way to save the computer is to call the toll-free helpline. This potentially dangerous program (PUP) inserts user’s OS version and the browser type in the message to make it look more trustworthy.

The message opens up in the browser and urges the victim to call a number provided, and if the user clicks “OK” or “Close,” the adware pops up a new alert message, and when the user attempts to close the new one, too, Sec-slihf.com malware displays yet another pop-up message. It goes on and on, making it hard to quit Sec-slihf.com website. However, you can quit Sec-slihf.com by continuously clicking “Close” or just by shutting down your web browser via Windows Task Manager (PC) or Force Quit Applications window (Mac).

Questions about Sec-slihf.com ads

  2. Fake tech support scammers attempt to get victim’s trust. They pretend to be professional computer technicians, and they try to confuse the victim by talking in technical jargon, or asking to complete meaningless tasks.
  3. Once they convince the victim that he/she is not skillful enough to cope with the non-existing problem, they dare to ask the victim to give them access to the computer. They might ask you to let them check your computer via Teamviewer or similar remote control software.
  4. If the victim gives the scammer access to the computer, the scammer might install malicious programs like ransomware (a virus that encrypts files and asks to pay a ransom later on) or change computer systems to make it vulnerable to computer threats. They might also install keyloggers on your PC in order to steal your banking information and other personal information.
