antivirus action virus

So, basically last night my laptop got infected with the antivirus action virus, and i wasn’t able to access webpages or even the task manager on my computer.
After searching for a solution, I found most were too complex for my understanding, so I went to bestbuy to get it fixed… unfortunately, they wanted $200CAD for the job, so I declined.
My boyfriend then guided me through an alternate system restore, which allowed me to access the internet and download the avast free anti-virus protection.
I wanted to make sure my laptop was free of the virus, so I did a full system scan, some viruses came up and I deleted the ones I could delete. Two of the ones that were indicators of the antivirus action virus, got an error saying… error: the system cannot find the file specified (2). i cleared my system restores, and did another scan.
Now what’s coming up is that some files cannot be scanned and furthermore an error comes up beside it saying … error: the system cannot find the path specified (3), beside the same suspicious file that keeps coming up due to the virus i had (have?).
I was wondering what exactly this means, and if I do have to go to a professional to get this problem fixed…

also i have attached a screenshot of the scan.
