My computer became infected recently when my AV (Symantec) recognized a virus. I do not remember the name of that virus, but the AV quarantined it immediately. As I was running an AV scan to look for additional trouble, a window popped up announcing some sort of 'exception' and the 60 second timer and the machine began rebooting, timing out on the timer, and rebooting again in a loop. Safe mode did not stop the timer. I found a DOS command that would stop the timer in safe mode ("cmd" 'enter') then ("shutdown -a" 'enter'). The timer iteration stopped at that point, but will reappear every time I reboot the PC.
I am running XP. I ran an AV scan that turned up nothing. I ran a 'FixBlast' removal tool on the hope that might fix the problem but it found nothing. I installed Malwarebytes and ran a scan and that found nothing. I tried AdwCleaner and that did not locate any known problems. I found some forums and ran the FRST and also the OTL scan tools. Then I read that I should not load additional programs or run tools more than once.
All the infection started on 5/21/14. Since that day, I have not connected to the internet when booting the PC. I have started the PC twice since then and run the scans previously mentioned.
Since I have done both FRST and OTL, I will attach the logs, not knowing which you may be interested in. Will greatly appreciate any assistance.
