Acting up is an understatement. It's been running very slow lately, I'm not sure what anti virus to try at one point or another I've tried basically everything. My friend told me to stick with the stock anti virus on windows 7 but it hasn't detected anything. I run CCleaner sometimes to clean up after program uninstalls. Hearing malware bytes is good? I just finished using bitdefender and it kinda sucked it didn't find anything it refused to scan my computer when I wanted it to it would just be on timer quick scans. Used Avast for awhile and it seemed to cause everything to slow down including my internet like it was capping my bandwidth or something once I removed it that fixed. I'm running windows 7 AMD Phenom II 965 black ( Quad 3.4ghz not overclocked. ) GTX 970 G1, 16GB DDR3, with 25mb cable connection. I've only been having this problem for about 2-3 days now. About to try malware bytes but any suggestions on other software would be helpful.
