text: do you know any free full version anti virus software which can clean all the viruses? i want a free full version anti virus software which can clean all the viruses (except avast anti virus because i found a virus named "broken.exe cutable" in a .dll file of avast anti virus) hi there,  the only other "free" security software ather than avast is avg.  however, i would strongly recommend avoiding this as it is currently only protecting against 90% of known viruses (letting one in ten through!) as opposed to the circa 99.3% protected by other paid-for programs.  this also doesn't protect you against spyware, adware, keyloggers, rootkits, etc.  my recommendation would be prevx1.  this is an all-in-one solution that will protect you against every type of malicious file/program and has the strongest protection and removal capabilities of all security programs available today.  download the free trial of prevx1 which will scan your pc and remove this and any other infections free of charge: http://www.prevx.com
