On my computer I have only one antivirus program. It is McAfee antivirus plus. I have not renewed the subscription and it currently runs with old updates. With the slow reboot I turned the antivirus off on reboot. It may run in some mode despite what I have done manually by un checking all boxes in msconfig including all those related to Mcafee.
In another thread on this site it was recommend that I check for malware using
malwarebytes
microsoft malicious removal kit
Kapersky
superantispyware
When I viewed superantispyware on www.downloads.com a user wrote that they got a trojan with the download and was not able to remove it with norton. So I did not download this software
I did check for malware with malwarebytes. The nearly 8 hour scan in full mode found no malware
I ran the download for kapersky anvirus and it found no malware
I ran the microsoft malicious software removal an it found no malware
In the past I had regularly used PCpitstop PCmatic which scanned for malware but have not used it recently
So with all of the malware checks at this moment reporting no malware I have some confidence with the multiple scans from different sources that scan with different definitions
With regards to competing software or conflicts I have no idea if this is happening
I would like to download and install the software programs such as the one you recommended and was warned not to download from company web sites and to use a trusted web site that screens downloads. So I have limited my downloads to www.downloads.com. Occassionally I will go to two cows but this software was not listed there. On a google search I found downloads available on other sites such as snapfiles and softpedia but i do not know if they have checked the downloads for malware as is done on downloads.com
What is the next step?
I downloaded the microsoft safety scanner. It indicates that it expires every 10 days. The version that I just used was 1.0.3001.0 and ran it in quick mode. It just completed successfully and no viruses, spyware, and potentially unwanted software were detected
