I suspect many of you have this problem since it is discussed on the web.

Recently I was infected with the Trojan horse Crypt3.BZBE at the position C:\WINDOWS\system32\ati2evxx.exe(various numbers within these brackets). It was detected and removed by AVGFree but reappears whenever I reboot my computer - with a different number in the brackets.

Since 26-MAY-15 an additional Crypt3 Trojan.BZBE has also appeared but only intermittently. It's location is at C:\WINDOWS\explorer.exe(various numbers within these brackets).It intermittently reappears whenever I reboot my computer - again with a different number in the brackets.

Has anyone been able to permanently remove these Trojans since they are described as dangerous by AVG. I'm moderately computer literate.

Grateful for any suggestions.
