I am new to this forum and this is my first post. I found out about bleepingcomputer.com while googling for a solution for malware infection. Really hoping that u guys can give me some good advice since I have no clue what's going on.. I will try to be as detailed as possible:
I am running 64 bit, windows 10 Home edition. For a few days I have noticed that, at times, my internet speed gets quite low for some of my activities. I have seen considerable reduction in speed while browsing the internet as well as during streaming videos. Sometimes, during browsing, I would get messages like webpage not available, only to to refresh it and find that im able to access the webpage.
I recently changed my router to Belkin 600 DB N+ Router. Previously I had been using a TP-Link TL-WR841N router. While setting up the new Belkin router, I accidentally kept the guest connection open (should have paid more attention). And couple of days later i started having internet connection issues.
Upon realizing that i kept the guest account open, I quickly added password to it and also changed the password on the other network connections as well (3 in total). I even changed the password for the the belkin web interface. But even then the problems persisted .. Every now and then, either I get disconnected from the network or even if I am connected, i get the "No Internet" indication on windows 10 wifi. On occasions I have noticed that random numbers were appended to the name of my network.
But the most terrible thing happened today. I kept getting very low speeds (~1.5 Mbps). I called the ISP and they informed me that everything seemed ok on their end. I downloaded Malwarebytes, disconnected from the internet and ran a "Threat Scan". MWB was able to detect 24 PUPs and 1 Malware. Deleted them all and restarted my PC. I then connected to my network normally and still found that i was getting quite low speeds. After about 10 mins or so, my router light turned red and there was no net connection!
So i disconnected the router and connected my old router (TP-Link) back. And I am getting good speeds again. So I am thinking my Belkin router might have been affected by the malware? I have read that malwares can creep back into PCs even after they are removed. In that case, I am afraid that my TP-Link router might also get infected? I am really not sure what to do. I have read that ComboFix maybe a last resort, butthat it should not be used unless its really required to.
I am really not sure what to do and how to disinfect my pc (and router). I am really hoping someone can point me in the right direction and give me a step by step process that I can follow to get my pc and router back to pre-infection state.
I even read that hackers can hack into PCs and router and can use the hacked PCs/routers as "bots". In case my PC/router has been compromised, is there any way I can get my system back?
Any help would be much appreciated! TIA! -Archie
