Hi guys I was wondering if anyone here know what to do. So my computer has been working crappy for a month, its old so I kinda get why. One of my Steam friends told me he could fix it and had me download Zoho Remote Support software to scan for viruses and malware and remove it because I never bought any anti virus software. My PC is pretty old, its a Dell Window 7 so he said he can speed it up.

He helped me get Zoho Anti Virus running and it removed a lot of junk from my computer but now its even slower and theres all weird pop ups. He said it might be that the viruses that he was removing are "cluster malware" so when u remove one, it installs several more. I dunno what to do to get my computer back to normal speed. I mean, I know I need a new desktop but I just dont have money for it right now.
