Could my computer get a virus?

Question

Alright, so say their are two computers in the house. One I bought and it runs off Wifi through a wireless router, which connects to my sisters home computer. We're both in separate rooms. Now if my computer or her computer gets a virus, would it be able to affect the others computer as well?

Answer 1

If you have a half-decent firewall, then no ... you cant get a virus from WiFi. Without a firewall, yes its easily possible. Try Zone Alarm:

It specifically asks you if you would allow other computers to share files with you from other computers, or if you want it to be strictly internet.

Answer 2

Yes, the entire Home Network computers. Much worst than a virus will be a botnet infection rifling/hi-jacking the computers into a botnet (zombie network). It is imperative to have at least WPA2 encryption enabled in Home Networks - the router and all computers connecting.



Some baddies that ocurr to an unprotected Home Network without the Router hardwall enabled - without personal firewalls and up to date real time protection antivirus and antispyware installed on each of the computers connecting.....



Nearly half of all home Wi-Fi networks could be hacked within five seconds, says CPP.

TIPS.... Hook up router with primary desktop and access the Router control panel through the manufacturer URL (address bar top) something like http: // 192 .167 .1.1

SEE your router manufacturer website for plain instructions as these with the correct address to access your router.... Enable the hardware firewall in the Router (effects nothing - blocks worst offenders from hijacks of your ISP connection). Enable WPA2 security encryption and set any password (good one) that is now the "security key" anyone getting onto your now protected Home Network must type once and save to get access to your Home Network (wi-fi connection).

Answer 3

Virus spreads when the computers are connected to the network. Whether connection is wired or wireless it doesn’t matter. If your computers are having web security then they will not get infected but if they don’t then your computer may get infected. I suggest you to have any good anti virus installed. Also if you want your computer to be secure from other web threats, then go for web security system.

Answer 4

yes, a computer connected to a network, can infect all other computers on the network it is connected to. The best solution is to purchase a top end anti virus such as kaspersky, preferably one that has a feature like Avast's sandbox browser. If you don't want to fork out money for a good anti-virus, you could go the cheapo route and get Avast free version, and google chrome.
