Hi guys, I need help ASAP!
A friend of mine wanted to copy some files from me, so I plugged in his USB and copied the files over. Later that day, my PC started to run significantly slower, and I’m pretty sure it’s because my friend’s hardrive, it must have contained a virus that copied itself to my PC.
For those who don’t know, 25% of viruses are spread through USBs, if you don’t disable the autorun on a removable media, then viruses can exploit the autorun.inf file, i.e they can use that file to automatically load and run the virus executables, and can of course copy themselves to your hardrive if they’re programmed to do that.
Unfortunately, I never took the autorun thing seriously, I had it enabled so the viruses must’ve copied it to my PC without a doubt.
So right now my problem is this, is it possible for a virus to copy itself and spread on a WIFI home network? There’re 4 members in my house including me, and we all have one computer each, so 4 computers in my home. We all use the same router to connect to the internet through WIFI, we don’t use file sharing, drive mapping or any of the sort.
None of us are connected to the router through LAN, there’re absolutely no connections between each computer at all. We just use our WIFI to surf the web, that’s all. But i’m paranoid about this, is it possible for a virus to somehow attack the router and then use the router to spread the virus to all those computers connected to it?? My router is pretty new btw, I got it only 3 months ago and it was provided free by my ISP (Vodafone), the router is EchoLife HG556a.
Anyway, I know a simple reformat will solve the problem, but i’m worried whether the viruses can spread through my home network through WIFI or my router somehow, I’m always connected to the internet so if this is possible, then my PC would’ve spread it to all the other computers in my house…
I’m paranoid about this because my PC was infected by a keylogger not too long ago, it stole my bank account information and some of the other stuff such as my Gmail account etc. It wasn’t too serious, but ever since then it has seriously changed the way I deal with viruses or keyloggers.
I have Comodo Internet Security installed and I’m planning to upgrade to the PRO version. But anyway I really need an answer on this, it seriously is bothering me so much that I haven’t touched my PC since a few days ago until I can get it solved.
■■■■ sorry it’s a bit long, I’ve tried to compress it but that’s the best I could do. I forgot to add in an important info. I think I have a keylogger and not a virus because CIS doesn’t detect anything after a deep/full scan, I used Microsoft Security Essentials, Super AntiSpyware, Emsisoft Anti-Malware, MalwareBytes Anti-Malware, Spybot Search & Destroy & Ad-Aware to scan my PC and all of them came out as clean and didn’t find a single thing. So the only possible reaosn is that I’ve gotten a keylogger, because as far as I know keyloggers are very hard to be detected, they’re not really viruses after all since they just record your keystrokes or what you see on the screen, but they don’t ■■■■■ up your system like most viruses do. Anyway i’m pretty ■■■■ sure my PC is infected coz it got a lot slower all of a sudden, and it NEVER gotten slower, only that after I connected my friend’s hardrive and it suddenly bogged it down. Also, after i finished copying files for him, my PC froze afterwards.
What’s more IMPORTANT is that I only reformatted my PC a few days ago so it couldn’t have gotten any viruses, everything was clean and running super fast, until my friend came over that day. I have a gaming PC and custom build it myself so everything is top notch, I know 100% it’s not lagging due to the hardwares, hell I could run Crysis, Starcraft 2 and DOTA all at once without any lag, can alt-tab between them fine as well so it can’t be due to hardware issues.
I’m running Windows 7 btw.
