Today I had to reboot my pc three times already because something strange is happening. And, although not 100% sure, I think it may have to do with Nod32. First, that little green icon in the taskbar does not stop turning, like it normally does. The balloon says that a startup scan is in progress. I can't remember that this would normally take more than a minute or so, but today it has been over 100 minutes now, and it is still busy. However, everything is working as usual. About two hours after startup, I can't surf the net anymore, the browser will stop to respond. Tried it with both Firefox and Opera. I can ping the router (192.168.1.1) but can't access it through the browser. There seems to be nothing wrong with the internet connection because Newsleecher is still downloading files with the same speed it allways does. Outlook does not respond anymore also. When I close Outlook and restart it, a message appears: "Outlook experience a serious problem with the eset outlook plugin add-in. If you have seen this message multiple time, you should disable this add-in and see if an update is available". I didn't open any attachments, however I do have a preview pane in Outlook open. This morning I received a junk mail from a sort of escrow company with which I had some problems in the past (I paid for a software license, didn't receive anything, they didn't respond to emails, and finally PayPal gave me the money back). I do receive spam from this company on a regular basis, delete it, and that was that. Can I be infected without actually opening anything, and with NOD32 monitoring the mail? The taskmanager shows that the process ekrn.exe*32 is using about 47% of the cpu, the rest is more or less idle. This was with version 4.2.40 of NOD32 (64 bit). The only thing I recently have changed in NOD32 was adding a weekly scan, but to run on sunday, not wednesday. I couldn't find an option to restore NOD32 to default settings so I decided to uninstall it manually (according to the instructions on the ESET site) and install the latest version 220.127.116.11 (64 bit). This didn't solve the problem, but the process ekrn.exe*32 takes now 25% rather than 47% with the previous version. I take monthly images from my C-drive, so I'm not in a panic and can allways go back to a previous state. A few files may have been altered or lost, so I like to hear if there are other options which I can try before that. Thanks. CPU Intel Q9400, 8 Gb RAM, OS=Microsoft Windows 7 Ultimate 64 bit with all the latest updates. Besides NOD32 18.104.22.168, Superantispyware is installed with realtime monitoring enabled.
