Internet explorer affected by malware/virus

If you cant start Internet explorer it might also be a problem that you have malware or a virus/trojan on your PC. To check for malware I have good experience with the (free) program 'Anti-Malware' from Malwarebytes. For virus scans I can recommend the (free) 'avast!' antivirus software.
It is a good idea to scan for malware/viruses every other while, because a functional virus/malware wont let you know it is there. If Internet explorer was broken by a virus, the virus might be incompatible with the IE version so you are lucky in the end :)
