I have a laptop I bought in 2005 (Windows 7) and I must have picked up an infection back when I was first setting it up. This computer has been in my office, offline since shortly after I got it.
A few months ago I got this computer online at my office on a wi-fi network.
After a virus scan, I found a two infected files a few weeks ago, a Malware Generator. I removed the infected files and did a second scan with Avast, then another with MalwareBytes. No infected files were found.
The other day I did another scan and found more infected files, which I removed. This time it was a program files > fwcsetup.exe. I read a little online about it and this is a target file for malicious attacks. The original location for this file was ProgramFiles - blg_fwupdate.
I found this fwcsetup.exe repair kit but don't know if I should use it at this time:
I've noticed sometimes when I'm turning off my computer a msg about a background program shutting down. It is gone before I can ID it. My knowledge of computers is not deep enough to look through my running processes and note any suspicious programs running.
I'm not sure how to proceed as I am basically uncomfortable messing around with such things unless I have very precise and clear instructions. I do have to transfer data via a flash drive from my other computer. How can I clear up this infection once and for all?
