Just yesterday I started noticing a problem, or issue at least, with my computer. Twice when I got up and left the computer on for a short time (i.e. 15-20 minutes), with the web browser on, the screen resolution had changed when I got back on the computer. No one else had done anything with the computer.
I have no idea whether this is related to some sort of malware issue or not, but the reason I wonder if malware might be involved is because the day before I got a notification from my anti-virus program, Avast, that I hadn't seen before. It said something to the effect that "a virus or trojan attempted to install on your computer, but was prevented. No further action is required." I didn't think at the time to write it down. After this I updated and ran scans with both Malwarebytes and Spybot. Neither of them found anything. I haven't noticed any other malware symptoms such as pop-ups or hijacking.
I had never had this screen resolution problem before, however, so that made me wonder. I hesitate to enter any important information (i.e. personal or proprietary) in my computer until I am certain that it's not malware-related.
If this is not a result of any malware, is it some sort of operating system issue? This is a fairly new computer. It's running Windows 7, which I have no experience with. I also have Office 2007, which is also new to me. I haven't changed the default screen settings (to my knowledge).
Thank you in advance for your replies. I appreciate the help.
