Are you running Ad Aware? if so completely remove it from your system, and then try reinstalling AVG. if this works you can always reinstall Ad Aware later
Yes I was running Adaware, but I did unistall Adaware and Malwarebytes and tried reinstalling Trend Micro (came with computer) & AVG and still have the same problem.
I realized after reading the forum guidelines, that I may have cause the problem myself. I was searching around the internet for answers to my problems and following suggestions from other users
to try different programs (adaware, malware, spydoctor combofix & a few others I cant remeber that I tried then unistalled). I think that I may have deleted an important file/s that I needed, rather than sending to quarantine. I also ran ComboFix before I stumbled on to this site. After reading the Combofix guidlines on this site, I probably shouldn't have run it until I was instructed to do so.
So now that I have read the posting guidlines for the formus, I realized that I may not be posting this in the right place. I have followed the steps and I will start a new topic with hijack logs in the " HijackThis Logs forums".
I apologize for duplicate postings. Please post any new replies under my new topic (same heading: unable to install any anti-virus programs) in the "HijackThis Logs and Virus/Trojan/Spyware/Malware Removal"
