A few months ago I got back home from overseas, and our shared pc had a backdoor.multi.zaccess.gen virus. Not sure how it got here while I was away, but I posted this on the malware part of the forum and did a complete scan and clean up on the infected computer.
See forum post below:
Now the virus is removed and the computer seems to be clean from any other viruses or infections, but as a consequence I cannot access the internet on this computer anymore.
When the LAN cable is connected, it shows the "internet" icon in the taskbar (two pc's + world globe), but browers do not work (i've deleted and reinstalled) and neither do any gaming applications.
Strangely, Steam was able to download updates, but no online games worked. Also some programs that need updates cannot download due to "no internet connection".
Our internet/router doesnt seem to be the issue, because everything works fine if I plug the lan cable into my laptop (which is used for internet now).
Not too keen on doing a fresh install just because of this small issue with internet connectivity.
