I have 2 computers. They run thru a Lynksys router. Computer No. 1 is wired and No. 2 is wireless. If I am on No.2 surfing the net ,can anything (such as a keylogger) get on No.1?
Hi, Why do you think the type of connection (wired/wireless) has any kind of influence on this? You have to install a Anti virus product on both PC's, and if you want also a firewall (although you're most likely protected against hackers by your Linksys device) and a general antimalware product, such as Malwarebyte's AntiMalware. In theory some viruses and malware can spread through the internal network but with both PC's protected the changes that will happen are very little. Then both PC's are secured evenly. Of course it's important to use a strong wireless key, like WPA or WPA2. WEP isn't enough.
Well I'm not the world expert on this BUT the answer(s) I have read to this type of question from Lynksys and others say "it's possible". Your SW FW's on both PC's should untrust the router in their settings and the router itself needs to have it's user id and psw changed from the factory default settings. The FW on PC # 1 should block all incoming packets from computer 2 as that is the only way "anything" can get passed. The much more likely threat is the same for both PC's you get infected directly from the www. That's my advice.
If the two computers arent really interacting, being behind the same router doesn't make it easier to infect the computer.
Possibly. It depends on the security setup between the two computers. If a worm gets to #2, it is possible to traverse the network to infect #1.
If Computer No2 has no shared files, any worm can infect No1. Sniffing in LAN is possible but You can prevent it on blocking all trafic on LAN in firewall (set Internet Zone for 192.168.x.x). cheers
