I got my computer back from ResNet today. They cleaned it. I confused on a few things though. When I got my computer, they said my computer had 200+ sources of malware on it. When they did the first scans on my computer using CCleaner, Malwarebytes, and Microsoft Security Essentials, they only picked up a few pieces of malicious data. It was only when they took the hard drive out of my computer and scanned it on another computer was when they picked up 200+ pieces of malicious data, which doesn't make a lot of sense. Like I said, I'm using 2-year subscription to Webroot SecureAnywhere on it. I've done HUNDREDS of scans (quick scans, full scans, custom scans), and NOTHING has popped up as malicious. I've even used Malwarebytes, CCleaner, and Microsoft Security Essentials in the past. Nothing was tracked as malicious. I checked my computer and none of the files I downloaded in the past, nor have any of the files I downloaded since I got on campus on 9/2 have been deleted. The last scan I did was before I went back to school in late August, and nothing was tracked as malicious or posed any threat to my computer or personal files. So I'm wondering if all this malware was caused when I connected to my friends router. I DID download files through my friend's router. I didn't stay with him long because we had VERY different personalities and I'm trying to really focus on school. I'm rooming in a single. When I tried to connect to the internet using an ethernet cord connecting to the wall, I had to install a program by my school to connect. The person at ResNet told me my firewall was temporarly down. I'm wondering if I could've caught the malware through this process. I have downloaded files on my computer in my single, but just youtube videos and stuff. Nothing dangerous (at least I think). The person at ResNet thinks this is related to my Webroot SecureAnywhere. So here are my new questions:
1) Is it possible to catch malware through connecting to an person's router and downloading files through that router?
2) Does Webroot SecureAnywhere (or ANY anti-virus software) shut down your firewall?
3) How do I turn-on my firewall since it's off now?
4) What should I do about all these other programs on my computer that ResNet installed on it (Open Fit, Windows Firewall with Advanced Security, Microsoft Security Essentials, CCleaner, and Malwarebytes Anti-Malware). I was told running more than 1 anti-virus on your computer is dangerous.
5) Could it be through connecting to my school's network through downloading and installing this program the reason all this malware was found on my computer?
6) If there was malicious data on my computer before this happened, could that put my external hard drives at risk? I backed up a LOT of data on 3 seperate external hard drives + flash drives. Again, NONE of the files that were detected as malicious were the personal files that I backed up on my hard drives + flash drives. I'm just worried that if there WAS malicious files on my computer at the time when I back my files up, they could be put at risk.
