infection. A 2010 study by America Online and the National Cyber-Security Alliance found that 82% of users’ PCs were infected by some form of spyware—
twice as many computers as were infected by viruses. Trojan:W32/DNSChanger is a pesky Trojan that will change the infected system’s Domain Name Server (DNS) settings, in order to divert traffic to unsolicited, and potentially illegal sites. If you tried to use anti-virus programs to scan your computer fully, then after a while during the scanning, the virus damage your internal network. Lately we got a few samples of this Trojan that were named ‘PayPal-2.5.200-MSWin32-x86-2005.exe’. This Trojan was programmed to change the DNS server name of a victim’s computer to 193.227.227.218 address. It seemed to be fine when you did a system restore to a point, but then infections will come back soon. That is crazy. The virus is hidden in the code of legitimate software programs—programs that have been infected, that is. When the host program is launched, the code for the virus is executed and the virus loads itself. Luckily, you can safely and absolutely get rid of Trojan:W32/DNSChanger here.
