Hello all. I'm not sure if this is a problem or not. To start out, I am running windows Vista home premium, with Norton 360. So I clicked on a link, and it took me to a website that had a really long, seemingly random set of characters in the address bar. Right after this, my Norton resource monitor gave me a pop-up saying that the "Microsoft Search Indexer had high disk write activity(209 MB total for this process)". Thinking my computer had been infected with something, I ran a virus scan with Norton-all ok. I then ran CCleaner, to remove any cookies/flash cookies etc that may have been stored on my computer. During the process, I got a popup from Norton download manager saying that the file was too new and couldn't be verified as safe. The files listed were ZZZZZZZZ-ZZZ and $RPYWURJ.exe. I don't know what these files relate to, but I know that a .exe file is some sort of executable. Now the panic set in, and I started trying different products that I already had installed, to see if they picked up anything. I tried Superantispyware, and Malwarebytes. Outside of a few tracking cookies, they came out clean. I tried Norton Power eraser-OK, and All above scans in Safe mode. All were clean. I also got aother pop-up from Norton dowload manager saying the file $RGPY19Q.exe, is too new and couldn't be verified as safe. Thinking that something may be hiding in the system restore files, I turned that off, restarted my computer and rescanned with Norton and Malwarebytes-all showed clean. I have no idea what any of these files do, or if the .exe is running something that may compromise my security. I am very nervous about doing anything important on this computer, until I know if it's infected or not. Help.
