Hello, I would appreciate any help with the following problem. Today I tried to open preferences in my personal Kerio firewall to edit some settings, and suddenly it started giving me the following error: === Microsoft Visual C++ Runtime Library Buffer overrun detected! Program C:\Program Files\Utilities\Kerio\Personal Firewall 4\kpf4gui.exe A buffer overrun has been detected which has corrupted the program's internal state. The programcannot safely continue execution and must now be terminated. === I made a clean install of the whole system to my new PC just a few days ago, and there haven't been any problems with Kerio earlier. I've been using this version for almost 1.5 years now, and never had anything like this. If this info helps, I permanently use Kaspersky antivirus (pro-active defense) and Kerio firewall, they are always on; periodically use SpyBot (with latest updates, immunized system) and AdAware. Neither has detected any possible malware. Please advise. I would like to make sure that something is actually wrong with my system, before taking any steps like those advised in your viruses/spyware/malware removal instructions.
