So I believe my computer may be compromised. It started with Firefox browser becoming stubborn, sluggish and force closing/crashing. But didnt give it a second thought. Recently its Got to the stage that it would actually freeze my computer and I would have to power off with main switch in order to restart. Uninstalled firefox. Resorted to chrome. Issue resolved. So I thought. Few days ago Mcaffee reported unwanted programme. It was located in downloads and was bizarrely a Utorrent.exe. It claimed it was infected with Artemis! (insert random numbers and letters here) A quick google suggested it wasn't a major threat. Weird. SO I removed it. Yesterday logged on to my computer and Mcaffee said new unidentified connection to my network. I couldn't really work out what the new connection was ( about 20 laptops/computers/android tablets/ phones/ chrome casts in my house) and it gave no more information. Also I regularly use ccleaner (daily) and have noticed that every time it prompts me to now close Microsoft edge and explorer. It has never prompted this in previous cleans and I most certainly never open edge. BUT today the thing i find most concerning is that on turning on my computer on first reflection of the desktop I immediately noticed that "show hidden files"' had been activated. Im very concerned. Also worth noting that when im playing games I get random minimize to task bar as if something has happened in background. Now i use Mcaffee total protection which is in its last month of subscription and have recently installed spybot search and destroy and malware bytes, of which both return 0 positives. Suggestions and ideas welcome.
