Ciao, aspettando i nostri esperti di sicurezza ti posso iniziare a suggerire di disinstallare sia avg antivirus che avg antispyware e di sostiturli Active virus shield e a2-squared e farli girare e vedere cosa ti combinano...
Poi per quanto riguarda il log di hijackthis mi dà come sospetti questi:


F:\sys.exe
O3 - Toolbar: &Barradell'Accessibilità - {11352A67-0178-46B1-8855-D50B2F81C054} - C:\Programmi\WAT_IT\Accessibility_Toolbar.dll
O4 - HKLM\..\Run: [Explorer] C:\WINDOWS\system32\expIorer.exe
O17 - HKLM\System\CCS\Services\Tcpip\..\{122DE63B-6FFD-4E88-A441-19B284D8E508}: NameServer = 83.224.66.134 83.224.65.134
O17 - HKLM\System\CS1\Services\Tcpip\..\{122DE63B-6FFD-4E88-A441-19B284D8E508}: NameServer = 83.224.66.134 83.224.65.134

Aspetta però il consiglio di crazycat o qualche altro esperto prima di fixarli.

Per la sostituzione degli antivirus/antipyware procedi pure

Alcuni di questi nomi sono regolari, però non dovrebbero essere in esecuzione, fai analizzare questi file sul sito www.virustotal.com e vedi quanti virus saltano fuori.
