welcome to the forum GaryTuz

i suggest you do a boot scan and send anything avast finds to the chest from there.

i would also suggest you do a scan with malwarebytes antimalware for a second opion.

http://www.filehippo.com/download_malwarebytes_anti_malware/ link to malwarebytes

for the malwarebytes download, install, update and do a scan and don’t forget to remove what it finds. Reboot of the system might be necessary.

good luck and let us know on the progress or, if you need more support.
