I want to upgrade to Windows 10 (I have 7) and then probably do a clean install as well. I'm not sure because I'm really confused now. I don't know what to believe anymore. It's very important to know if I'm infected because I decided to do the clean install to get rid of whatever malware I caught and now I'm asking myself how to backup some files on my USB without infecting the new Windows afterwards.
So,I suspected I have a virus but I'm kind of a maniac so I posted my problem on a forum but not at any virus/malware section.
I was asked to post some logs about my system and HDD; everything was fine with the HDD but I think they found something suspicious on my system logs because they said to move on another section for infected computers.
Nobody particularly said that I have malware,but they told me to go ask there.
I worked with anti-malware programs before and I know what to run so I didn't ask anymore. Instead, I did my own research.
Now,about my problems,there is nothing really bothering. It was just a BSoD (9f code) during hibernation/sleep (I am not sure because I let the laptop plugged and didn't pay attention to it for more than 1 hour),but it happened only once 1 week ago. Also,it got stuck during logging off and shutting down; I had to hold the power button to shut it. This happened twice. Only once I thought it was stuck but it did shut down by itself eventually. I also noticed my laptop is slow at startup (but not much more slower than usual). I have Skype that automatically opens so I kind of suspected that might be the problem. I got an error once saying Windows has stopped working because I always insist on running some tasks when it just opened and it's not ready to use. Now I wait patiently until it's ready.
These things don't bother me. I do my work without problem. Aside from startup my laptop is as fast as usual and it doesn't freeze.
These problems could also come because I have lots of updates I try to install but I can't. Windows 10 automatically installs before the updates and I did everything to make it stop but it just continues. I'll get rid of this anyway when I upgrade.
I also updated Avast. I don't usually scan regularly with it but it didn't bother me with pop-up messages about viruses and trojan.
I scanned with Malwarebytes anti-malware yesterday. Nothing was found. I tried Malwarebytes anti-rootkit and Kaspersky TDSSkiller. The last one didn't find anything. Malwarebytes anti-rootkit did something strange and I also emailed them to make sure the program might have bugs. I extracted it and then a message appeared (before scanning!) saying "probable rootkit activity". I scanned with it and it found nothing. I closed and reopened it. I had to extract it again and the message popped up again.
I don't know what to try anymore and I can't decide if I have or not a malware problem. I tend to think I don't have any malware issue because I really hate malware and viruses and as a result I am very careful on websites and I have anti-anything bad programs. But I also know from my experience that nasty viruses don't show their faces immediately.
