Run a full scan with Malwarebytes Antimalware - no issues found The thing is, I have never activated this option, as the PC is set to go directly onto the desktop, without asking to click on usernames, or typing passwords. Yesterday morning my PC asked me to log in by clicking on my user name. Yesterday another one of my AV shields (Malwarebytes Antiexploit) reported that an exploit code was blocked in Firefox, but without giving more detailsģ. My AV Provider (Bitdefender) sent me a message saying that it is about to stop supporting my OS (Win XP)Ģ. No other issues reported - slow system, unwanted downloads, opening unwanted links, etcĮVENTS HAPPENED RECENTLY THAT MAY BE RELATEDġ. I did not find any particular pattern (ie, websites, time of the day, open apps, amount of time online, etc) - it appears rather random. When it reopens, it goes back to the latest situation prior to the shut down event, ie, it reopens all closed tabs and the closed web links - as if it were a crash.

The shut down is triggered by a click, typically a click to open a link, or open a new tab - that is, it does not shut down by itself.įirefox does not reopen by itself, you must reopen it. It typically happens once, max twice a day and when it happens, it closes all open tabs without giving any warning and without showing any error or crash report. About 1 week ago, Firefox started to randomly and suddenly shut down.

Itunes reopens after closing
