Sometime today I noticed a blocked outgoing event in my ZoneAlarm Free Firewall log, it was going out from my computer to port 13568. I asked on http://www.pchelpforum.com what it could be & 1 of the tech members suggested it may be malware. Although I've run scans with MSE only to find nothing, in addition to this my computer runs fine. He also suggested that I download & run something called "OTL" via this link http://oldtimer.geekstogo.com/OTL.exe. However, there is 1 bad review by a Norton Safe Web user regarding the site to download OTL from. Should I trust the link & download this anyway to see if there is any malware on my system that MSE can't detect?
