I had avast antivirus but uninstalled it (had it for approximately 3 - 4 years) because it kept on prompting me to reboot even after just logging on to the internet. Their latest version is 4.8. I got sick of the popup messages so I went looking for another antivirus program which is just as good as avast. I did a search on the internet and I came across Comodo antivirus and it's free. It also has Comodo Internet Security (which is also free) and I also use Comodo Antispam which I would recommend to anybody looking for such a program. I don't have any spyware removal software as yet, so can anybody recommend a good one? I am very security conscious.
I am using Avast and it is good. But as I am not an expert I can't suggest you anything surely. I think you should consult an expert who can suggest you the right thing you need. If you find it difficult you may visit "link removed" (Fraud, scam, phishing site) for help. The staffs out there helped me a lot while my computer was infected with viruses and the hard disc was crashed. They are skilled enough to solve any kind of tricky problem related to computer. I think they will be able to able to guide you properly and help you to install the best antivirus in your pc if you get in touch with them.
