I'm currently using bit defender 9 internet security but the virus scanner is taking forever with an estimated time of over 5 hours. Last night, it got to 18% after an hour, and had scanned over 400,000 files. I didn't finish the scan. I used to use pc cillin and that scanned within an hour and as far as I know was thorough. How do you rate bit defender and should I untick some boxes to speed things up like, the heuristics scan? Alternatively, what is the opinion on the free AVG? Is it thorough and does it keep up to date with the latest definitions? Finally, is it worth using an online scanner? I can't remember if online scanners actually fix viruses or just find them and then want you to buy their product. Thanks in advance.
