I bought a newer Dell PC with dual core processor and Win 7. The seller recommended Avast AV. I had been using MSSE for the last few years, but I thought I'd try Avast and see how I like it. After I installed Avast I could not send email out, so I called their toll free "support" line and got some man with a foreign accent that got onto my PC and said I have a Trojan and Koobface, and wanted me to pay $99 fee to supposedly clean it up [which I didn't do]. I didn't like talking to the man, he seemed push to get me to pay some money, and I ended up hanging up on him and unchelcked logmein123.com on my firewall. He claimed he works for MS, but I doubt he does. Ths gave me a bad feeling about Avast.
Anyway, how do I remove a Trojan, if I have one?
I ran Malwarebytes but to tell you the truth, in all the years I've had MWB, I have never seen it detect a single tghing from any of my PCs.
I ran SAS and removed 7 tracking cookies but nothing else.
Which free AV is the best? I installed AVG and I now have that running. I've heard that Avira will remove a trojan, is that true?
What should I do to clean up my PC and hopefully not pay someone to do something that can be done at no cost?
I love my new Dell PC. It's Pentium D dual core with 3 GB RAM, 2.8 Ghz, Win 7.
Thanks in advance.
