I was infected by USB flash memory while attempting to help another computer... sigh...
At the time of infection I was running Avast 4.8 and thought that I was protected, but I was not!
Now I've tried many antivirus programs including Norton, Avast 5, Trend Micro and Comodo and none of them could detect the virus... even Avast's famous boot time scan failed to detect anything...
I have submitted a few suspected files to Kaspersky via the online file analysis submission tool and Kaspersky seems to be able to detect the virus, so I downloaded PURE, but when I tried to install, the program runs ok until the end when it simply rolled back and informed me that an error had occured and I have to restart my computer to complete the process, but no matter how many times I restarted, nothing happened. I'm very disappointed in all anti-virus programs so far... please help me overcome this problem.
Regards.
