Description: ZLOB
Trojan (Mssearchnet.exe, Nvctrl.exe, Mscornet.exe) is an advertising trojan that installs secretly and starts generating pop-ups
on the infected computer. Often, these pop-ups claim that the user's computer
is infected and recommend a rogue product to remove the infection. Lately, ZLOB
Trojan has been promoting several questionable anti-spyware products, among
which are System Doctor, SpywareStrike, SpyAxe, SpyTrooper, Malware Wipe,
Adware Punisher, Spy iBlock and SpyGuard.
ZLOB Trojan also generates warning messages that can look like system messages
(see sample below), and these messages direct users to install the fake
anti-spyware products from this list of
websites. It is highly recommended to remove this trojan as it does transfer back and forth information
from the infected computer which makes it a potential for data theft.
Zlob Trojan hijacks computers to various rogue
anti-spyware websites, many of which look similar to screenshot below:
