Trojan horse Downloader.Zlob.CU
Hello everyone 
This morning, like every morning, AVG udpated itself then proceeded to execute it's daily virus-scan. To my complete surprise :wow: it actually detected and healed the following Trojan horse :
Downloader.Zlob.CU
Not being totally convinced
that this little problem had been dealt with efficiently, I downloaded and ran the latest updated version of CWShredder. This came up spotless.
After rebooting, I then updated and ran SpyBot - Search & Destroy, and Ad-Aware SE Personal. Both of these, like every morning, came up clean.
Still not totally convinced that the parasite had been totally eradicated, I downloaded the latest version of HijackThis and scanned my PC. The following log was created :

I can't see anything suspicious in this log myself. However, just to be on the safe side, I would be extremely grateful if one of you lovely people
could sift through it and see if you can spot something I may have overlooked.
Many Thanks
