It is possible for certain types of malware (i.e. worms) to spread on a local LAN behind a router and for some types of malware to infect router firmware and change the router settings.

Routers can be compromised if they have a weak or default password which attackers can easily guess or break using a dictionary attack or brute force attack. Malware which can modify routers are rare and may require the router to be a specific make, model and firmware revision. The most common was the DNSChanger Trojan which compromised the router's weak default password using brute-force attacks. The Trojan then changed the router's DNS table to malicious DNS servers...redirecting Domain Name resolutions to unsolicited, illegal and malicious sites the attacker wanted victims to access.
 

...Some DNS changer Trojans can alter routers' DNS settings via brute-force attacks. As a result, all systems connected to the "infected" router also become infected. Some DNS changer Trojans can also be used to set up rogue Dynamic Host Configuration Protocol (DHCP) servers on certain networks, which can have the same effect.

Malware Silently Alters Wireless Router Settings

Some routers have known vulnerabilities which can be exploited to open them up to attacks without needing to know the proper password. There have been various reports of vulnerabilities and attacks against hardware devices such as routers and data storage. For example, Ars Technica reported that ASUS routers and any storage devices attached to them may be exposed to anyone online without the need of login credentials if users have taken advantage of remote access features built into the routers. Linksys routers have been reported to be vulnerable to a simple exploit that could give an attacker remote access to the router.Related ResourcesWiFi Security Risks

browser hijackers are generally related to Potentially Unwanted Programs (PUPs) which are bundled with free software you download and install on a specific machine.
