Can a virus stop network adapters to work? I having a right problem with computers and it just gets stranger, If had 2 problems lately that are probably related seen as its happened on 2 desktop pcs I have. My both machines have had freezes but they haven't froze anymore recently but I've not had it on for too long so the problem maybe still exist. This is now turning into something else. I turned it on last night and it wouldn't connect to the internet after failing to load windows 7, went to a black screen so I powered off and then it repaired intself it said but then no internet. I tried with my old windows xp and no internet on that either, reset netgear router and tried to put in routerlogin.com, but just said cannot find the page, both pcs said this too. So I phoned the ISP this morning and they said all is ok their end and with it not working on both machine it's most probably be a router that is gone, try a mates one. So I tried my mates sky one and nothing but thought that might be because it was a sky specific and then remembered we had an old BT voyager in the loft and try this, it didn't work either when I put in the voyager.home or the ip address to login. So then I tryed the laptop just to see and low and behold it works plugged into this BTVoyager, this is how i'm writing this now. Anyone know why it doesn't connect though to the desktops with ethernet cable. Can a virus of spread, lied dormant in them and now making them freeze and now no internet. I'm just tearing my hair out trying to phathom out why it is not seeing the BT voyager or the netgear, obviously it's not the router afterall but both machines getting a network adapter problem at the same time sounds unlikely doesn't it. Can viruses effect network adapters. Anyone have any suggestions, I've ran both comodo and avira anti-virus and neither found anything the other day. Update: checked the anti-virus on the Windows 7 and it won't let me do a scan, worked ok the other day though as I say. I really don't want to have all to format both machines back to the factory settings as it would take so long to do. Is there a way I can get a upto version of a anti-virus on a disk or external via this laptop thats connected and run some scans. Any advice would be great. Original freezing problem: I really don't know what is happening to my computer, weather its a virus or what. But this is how it happened. 3 weeks ago my psu went wrong in my main Windows 7 computer and I got a new PSU ordered from my PC manufacturer as it was still under warranty. All fair enough, I had a Samsung internal disk drive in my PC with all my storage files on and a Intel SSD for boot. I decided whilst I was waiting my new PSU to arrive I would but my Samsung storage drive in my old Windows XP PC. This is when it happened, I was clearing out and edited some files on my drive when it froze on me just got stuck I couldn't close it with task manager, everything just frooze and you couldn't open anything. I then couldn't see the drive in my disk manager or in windows. So I thought oh well, the drive is dead, so I ordered a new one. I had everything backed up on an external. After that the PC loaded but it took much longer to load and as I say you couldn't see the samsung drive, I took it out and it loaded quick again. Now I got my new PSU and fixed that and all worked fine, great I thought, I figured I'll just try the old Samsung storage drive in my new main windows 7 PC, but this time it shows up fine again and I could few everything again. Oh waste of money buying a new one but great news, then it freezes this PC this time. Oh hell, I take it out and am convinced it's currupt or something. I just run my SSD drive this time and all other drives unplugged so just my ssd boot drive and run my Comodo internet protection anti virus scan, malware bytes and Tune-up but none came up with anything that stops it freezing. But it still crashes my computer, completely randomly, I have to turn off at standby and restart it that way, it maybe hours before it does it again but it will just like have the spinning windows 7 loading circle appear and when I click on anything nothing happens, just freezes. Has anyone heard of this very odd problem, I don't know if its a virus that has spread from the old samsung drive or some hardware fault, or what, I just don't know what to do.
I had something similar, my PC went form perfect to a bag of crap over night. I went to bed it was fine, booted up the following and got BSOD about 5 times as soon as the desktop loaded, everything was failing looked like a totally corrupted OS. The upshot was I had to reinstall. The following day my son had the same thing. The only connection I could find between mine and his set up is that we both use Microsoft security essential and what ever it is that's going round , it doesn't pick it up. I had all the same probs as you including not connecting to the internet. I couldn't even restore as it just threw up a file error every time I tried. tried malware bytes and it wouldn't load , what ever it is it creeps in and borks everything. Edit: I'm wandering if this isn't something to do with Zero day vvirus that gets at you via internet explorer.
No issues here on both my laptop and desktop, mother computer, brother computer (big IE user), my brother, all running Windows 7 64-bit. [edit] I just got a reply from 2 friend (3 computers total), Windows 7 64-bit for 2, and one with the 32-bit version, no issues to report. [/edit]
Hi yeah I don't use Internet Explorer, only firefox and have always had upto date virus protection, well so I thought before this happened. Is there anyway I can put an updated anti-virus program on the desktops. Most anti virus programs don't have an up to date version do they that I could download and install on the desktops. apart from the inernet not being available they seem ok. I have all my data on an external drive but how do I make sure there is no virus on that that will reinfect my PC as soon as I hook it back up if I did have to do a complete reinstall of the OS.
Once you are infected with a virus (like the virus attacks your computer and notjust in a file waiting to be executed), their is absolutely no fix. Once it deletes or modifies Windows files, then it's done. You need to re-install.
I'm still not entirely sure it is a virus, it probably is but its not one Avira finds, I managed last night to get avira re-installed and i now works but no virus found, thats probably though cause it's done the damage. Can a virus be programmed to lie dormant and then strike on a date. When I turned on Christmas night it just went black screen whilst loading and then no internet. I can only think it got passed when I tried the old Samsung storage drive on my windows 7 PC, I wished I'd not done that now, it might only of infected the old one. But the drive didn't have anything from any dodgy sites, various free graphic design tutorials on stuff which is what happened when I opened or tried to open one of these directories is when it started to freeze. Maybe that's what let it out, I dunno. It's all so very annoying.
Run Tdss killer from kaspersky and smitfraudfix, both can be saved to a USB dongle and are free downloads
The way it hit me I think it's once you reboot and the anti virus hasn't loaded thats when it strikes, like I said before, I turned of a perfectly working PC and the following evening when I booted it...Totally Borked. And talking of hiding viruses about 5 years ago there was one that would hide in the router and kill a PC stone dead. Edit: I'm wondering if thats where this Fu*ker was hiding, Non of the PC's in my house that are on wireless have been affected, only the 2 thats are hard wired and I had to mess about the other day and reset the router because it was really acting up. The virus I mentioned from before was easy to kill simply by reseting the router to default factory settings, I hard wired then aswell.
Yeah viruses are one huge pain in the ass, this is the first one I've had in years but it's doing my head in as it takes so long to rectify or know what to do for the best to get rid of it. Cheers for the tips on Tdss killer from kaspersky and smitfraudfix, i'll give the latter a miss though as I've seen no taskbar popups of anything like it mentions. That virus that was dormant for 5 years in the router sounds terrible, I had no idea a virus can be that devious to get into routers. I've purchased now ESET Smart Security which sounds good for a good price to hopefully get rid of this virus. Should I ring my bank and get important passwords changed, or am I being over paranoid.
It hid in the router but not for 5 years, it happened about 5 years ago...lol. At the time I Tried everything ,in the end I worked out it was somewhere in the network, I rang BT who denied any knowledge of it so I told them to disconnect me. a while later some one rang me back who could actually speak English and said it was in the router and said by resetting it , it would sort it out.
a lot of routers have linux based code, so only takes someone with a knowledge of writing linux code, and router backdoors (telnet - default passwords etc) and they can effectively hide a virus in the router. the route of infection would more thank likely be write a virus that runs on windows pc, include code to telnet into router and edit the linux coding in the router to include virus.
well once you get in the habit of keeping known good backups- these types of things are nothing cleaned machines.. it always went back to porn or limewire related, or the guy ran everything put into his mailbox.. knowing how to use the uac is the best defense you don't even need an antivirus if you have a base backup and uac turn all the way up, execute new apps in a vm that has some sort of antivirus installed.. password all shares on the network and have a good firewall.. but it only works if you don't let your nieces and nephews on your rigs xD wireless access should be limited too- if your running wep for example.. expect to have people using your bandwidth like it's their own.. wpa2 aes should be good also if you can't help yourself.. do your porno in a vm- what happens in vegas stays in vegas.. most people don't know where all the caches are anyway, so nuking the vm is easier + keeps your rig clean
